Search a folder hierarchy for filename s that meet a desired criteria: Name, Size, File Type - see examples. GNU find searches the directory tree rooted at each given file name by evaluating the given expression from left to right, according to the rules of precedence see Operators , until the outcome is known the left hand side is false for AND operations, true for OR , at which point find moves on to the next file name. The -H, -L and -P options control the treatment of symbolic links. That argument and any following arguments are taken to be the expression describing what is to be searched for.

Search a folder hierarchy for filename s that meet a desired criteria: Name, Size, File Type - see examples. GNU find searches the directory tree rooted at each given file name by evaluating the given expression from left to right, according to the rules of precedence see Operators , until the outcome is known the left hand side is false for AND operations, true for OR , at which point find moves on to the next file name.

The -H, -L and -P options control the treatment of symbolic links. That argument and any following arguments are taken to be the expression describing what is to be searched for. If no paths are given, the current directory is used.

If no expression is given, the expression '-print' is used but you should probably consider using '-print0' instead, anyway. This manual page talks about 'options' within the expression list.

These options control the behaviour of find but are specified immediately after the last path name. The three 'real' options -H, -L and -P must appear before the first path name, if at all. Never follow symbolic links. This is the default behaviour. When find examines or prints information a file, and the file is a symbolic link, the information used shall be taken from the properties of the symbolic link itself. Follow symbolic links. When find examines or prints information about files, the information used shall be taken from the properties of the file to which the link points, not from the link itself unless it is a broken symbolic link or find is unable to examine the file to which the link points.

Use of this option implies -noleaf. If you later use the -P option, -noleaf will still be in effect. If -L is in effect and finddiscovers a symbolic link to a subdirectory during its search, the subdirectory pointed to by the symbolic link will be searched.

When the -L option is in effect, the -type predicate will always match against the type of the file that a symbolic link points to rather than the link itself unless the symbolic link is broken. Using -L causes the -lname and -ilname predicates always to return false. Do not follow symbolic links, except while processing the command line arguments. When find examines or prints information about files, the information used shall be taken from the properties of the symbolic link itself.

The only exception to this behaviour is when a file specified on the command line is a symbolic link, and the link can be resolved. For that situation, the information used is taken from whatever the link points to that is, the link is followed. The information about the link itself is used as a fallback if the file pointed to by the symbolic link cannot be examined. If -H is in effect and one of the paths specified on the command line is a symbolic link to a directory, the contents of that directory will be examined though of course -maxdepth 0 would prevent this.

If more than one of -H, -L and -P is specified, each overrides the others; the last one appearing on the command line takes effect. Since it is the default, the -P option should be considered to be in effect unless either -H or -L is specified. GNU find frequently stats files during the processing of the command line itself, before any searching has begun. These options also affect how those arguments are processed.

Specifically, there are a number of tests that compare files listed on the command line against a file we are currently considering. In each case, the file specified on the command line will have been examined and some of its properties will have been saved.

If the named file is in fact a symbolic link, and the -P option is in effect or if neither -H nor -L were specified , the information used for the comparison will be taken from the properties of the symbolic link.

Otherwise, it will be taken from the properties of the file the link points to. If find cannot follow the link for example because it has insufficient privileges or the link points to a nonexistent file the properties of the link itself will be used. When the -H or -L options are in effect, any symbolic links listed as the argument of -newer will be dereferenced, and the timestamp will be taken from the file to which the symbolic link points.

The same consideration applies to -anewer and -cnewer. The -follow option has a similar effect to -L, though it takes effect at the point where it appears that is, if -L is not used but -follow is, any symbolic links appearing after -follow on the command line will be dereferenced, and those before it will not. The expression is made up of options which affect overall operation rather than the processing of a specific file, and always return true , tests which return a true or false value , and actions which have side effects and return a true or false value , all separated by operators.

If the expression contains no actions other than -prune, -print is performed on all files for which the expression is true. All options always return true. Except for -follow and -daystart, they always take effect, rather than being processed only when their place in the expression is reached.

Therefore, for clarity, it is best to place them at the beginning of the expression. A warning is issued if you don't do this. This option only affects tests which appear later on the command line. Dereference symbolic links. Implies -noleaf. The -follow option affects only those tests which appear after it on the command line. Unless the -H or -L option has been specified, the position of the -follow option changes the behaviour of the -newer predicate; any files listed as the argument of -newer will be dereferenced if they are symbolic links.

Similarly, the -type predicate will always match against the type of the file that a symbolic link points to rather than the link itself. Using -follow causes the -lname and -ilname predicates always to return false.

If you give this option and a file is deleted between the time findreads the name of the file from the directory and the time it tries to stat the file, no error message will be issued.

This also applies to files or directories whose names are given on the command line. This option takes effect at the time the command line is read, which means that you cannot search one part of the filesystem with this option on and part of it with this option off if you need to do that, you will need to issue two find commands instead, one with the option and one without it. An alternate name for -xdev, for compatibility with some other versions of find. Each directory on a normal Unix filesystem has at least 2 hard links: its name and its '.

Additionally, its subdirectories if any each have a '.. When find is examining a directory, after it has statted 2 fewer subdirectories than the directory's link count, it knows that the rest of the entries in the directory are non-directories 'leaf' files in the directory tree. If only the files' names need to be examined, there is no need to stat them; this gives a significant increase in search speed. Currently-implemented types are emacs this is the default , posix-awk, posix-basic, posix-egrep and posix-extended.

These warnings apply only to the command line usage, not to any conditions that find might encounter when it searches directories. The default behaviour corresponds to -warn if standard input is a tty, and to -nowarn otherwise. If file is a symbolic link and the -H option or the -L option is in effect, the access time of the file it points to is always used.

When find figures out how many hour periods ago the file was last accessed, any fractional part is ignored:. A file To match a date range you can specify more than one test. If file is a symbolic link and the -H option or the -L option is in effect, the status-change time of the file it points to is always used. See the comments for -atime to understand how rounding affects the interpretation of file status change times.

The valid filesystem types vary among different versions of Unix; an incomplete list of filesystem types that are accepted on some version of Unix or another is: ufs, 4.

If the -L option or the -follow option is in effect, this test returns false unless the symbolic link is broken. In these patterns, unlike filename expansion by the shell, an initial '. Please note that you should quotepatterns as a matter of course, otherwise the shell will expand any wildcard characters in them. It is normally easier to use the - samefile test instead. This option is deprecated, so please do not use it. See the comments for -atime to understand how rounding affects the interpretation of file modification times.

To ignore a directory and the files under it, use -prune; see an example in the description of -wholename. Braces are not recognised as being special, despite the fact that some shells including Bash imbue braces with a special meaning in shell patterns.

The filename matching is performed with the use of the fnmatch 3 library function. Don't forget to enclose the pattern in quotes in order to protect it from expansion by the shell. If file is a symbolic link and the -H option or the -L option is in effect, the modification time of the file it points to is always used. The predicate -path is also supported by HP-UX find. Since an exact match is required, if you want to use this form for symbolic modes, you might have to specify a rather complex mode string.

Symbolic modes are accepted in this form, and this is usually the way in which would want to use them. You must specify 'u', 'g' or 'o' if you use a symbolic mode. Symbolic modes are accepted in this form. If no permission bits in mode are set, this test currently matches no files. However, it will soon be changed to match any file the idea is to be more consistent with the behaviour of perm This is a match on the whole path, not a search.

For example, to match a file named '. The regular expressions understood by find are by default Emacs Regular Expressions, but this can be changed with the -regextype option. When -L is in effect, this can include symbolic links.

The following suffixes can be used:. The 'b' suffix always denotes byte blocks and never 1 Kilobyte blocks, which is different to the behaviour of -ls. If you want to search for symbolic links when -L is in effect, use -xtype. To ignore a whole directory tree, use -prune rather than checking every file in the tree. For symbolic links: if the -H or -P option was specified, true if the file is a link to a file of type c; if the -L option has been given, true if c is 'l'.

In other words, for symbolic links, -xtype checks the type of the file that -type does not check. Use operators to separate multiple actions. If the operator is omitted, - and is assumed. The default action is to -print all files for which the expression is true.

The find command in UNIX is a command line utility for walking a file hierarchy. It can be used to find files and directories and perform subsequent operations on them. It supports searching by file, folder, name, creation date, modification date, owner and permissions. It will search for sample. Output :.

The Linux find command is very powerful. It can search the entire filesystem to find files and directories according to the search criteria you specify. Besides using the find command to locate files, you can also use it to execute other Linux commands grep , mv , rm , etc.

If you are not sure about the command name and want to search for a string here ps , type:. Each time a new package is installed, the associated man pages are added but the index database is not directly updated. If you want to update this index database used by the whatis and apropos commands without waiting for the cron update, type:. Also, some commands here ipc offer additional documentation that you can get as follows:.

Whether you're a Windows system administrator looking to expand your skills into Linux, a fresh convert to Linux, or someone who's looking to find a job in IT, this introduction to some common Linux commands is for you. These 10 commands are the ones that Linux system administrators use frequently—in fact, they use at least eight of them on a daily basis. And no matter how long you use Linux, you'll always use these commands. Some of you MS-DOS users will recognize a few of these and, not surprisingly, they have the same function in both operating systems. A large number of files over appear on your screen.

The Linux Find Command is one of the most important and frequently used command command-line utility in Unix-like operating systems. Find command is used to search and locate the list of files and directories based on conditions you specify for files that match the arguments. Find can be used in a variety of conditions like you can find files by permissions , users , groups , file type , date , size , and other possible criteria. Through this article, we are sharing our day-to-day Linux find command experience and its usage in the form of examples. In this article, we will show you the most used 35 Find Commands examples in Linux.

Затем Сьюзан сунула ноги в туфли и последовала за коммандером. - Какого черта ему здесь надо? - спросил Стратмор, как только они с Сьюзан оказались за дверью Третьего узла.

- Стратмор пожал плечами.  - Фонд электронных границ замучил неприкосновенностью частной жизни и переписки. Сьюзан хмыкнула. Этот фонд, всемирная коалиция пользователей компьютеров, развернул мощное движение в защиту гражданских свобод, прежде всего свободы слова в Интернете, разъясняя людям реальности и опасности жизни в электронном мире.

Отсюда выглядит просто отлично. - Да ну тебя, Чед, - засмеялась.  - Я гожусь тебе в матери.

Что, черт возьми, делает Фонтейн? - Смяв в кулаке бумажный стаканчик, она с силой швырнула его в бачок для мусора.  - В шифровалке творится нечто непонятное. Я чувствую. Она знала, что есть только один способ доказать свою правоту - выяснить все самой, а если понадобится, то с помощью Джаббы. Мидж развернулась и направилась к двери.

Стратмор требовал запретить всяческий доступ, но Фонтейн настоял на. - В шифровалке нет камер слежения? - удивился Бринкерхофф. - А что, - спросила она, не отрываясь от монитора, - нам с Кармен нужно укромное местечко. Бринкерхофф выдавил из себя нечто невразумительное. Мидж нажала несколько клавиш.

- Я просматриваю регистратор лифта Стратмора.  - Мидж посмотрела в монитор и постучала костяшками пальцев по столу.  - Он здесь, - сказала она как о чем-то само собой разумеющемся.

Это был уже не тот раздавленный отчаянием человек, каким она видела его десять минут. Коммандер Тревор Стратмор снова стал самим собой - человеком железной логики и самообладания, делающим то, что полагалось делать.

Последние слова предсмертной записки Хейла крутились у нее в голове, не повинуясь никаким приказам.

Однако тот не подавал никаких признаков жизни. Сьюзан перевела взгляд на помост перед кабинетом Стратмора и ведущую к нему лестницу. - Коммандер.

Хотя, быть может, подумал Халохот, Беккер не видел, как он вошел в башню. Это означало, что на его, Халохота, стороне фактор внезапности, хотя вряд ли он в этом так уж нуждается, у него и так все козыри на руках. Ему на руку была даже конструкция башни: лестница выходила на видовую площадку с юго-западной стороны, и Халохот мог стрелять напрямую с любой точки, не оставляя Беккеру возможности оказаться у него за спиной, В довершение всего Халохот двигался от темноты к свету.

Сьюзан окаменела.

Сьюзан спустилась по лестнице на несколько ступенек. Горячий воздух снизу задувал под юбку. Ступеньки оказались очень скользкими, влажными из-за конденсации пара.

Она присела на решетчатой площадке. - Коммандер.

А метод грубой силы? - предложил Бринкерхофф.  - Можно ли с его помощью найти ключ. Джабба всплеснул руками. - Ради всего святого. Шифры-убийцы похожи на любые другие - они так же произвольны. Угадать ключи к ним невозможно.

Беккер лихорадочно осмотрел его в поисках укрытия, но задняя стена ангара, громадный щит из гофрированного металла, не имела ни дверей, ни окон. Такси было уже совсем рядом, и, бросив взгляд влево, Беккер увидел, что Халохот снова поднимает револьвер.

Повинуясь инстинкту, он резко нажал на тормоза, но мотоцикл не остановился на скользком от машинного масла полу. Веспу понесло .
