Combine Linux find and grep with exec

Site Logo

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 just want to see some examples and skip the reading, here are a little more than thirty find command examples to get you started. Almost every command is followed by a short description to explain the command; others are described more fully at the URLs shown:.

If you know of any more good find commands to share, please leave a note in the Comments section below. If it finds the file, it prints the location to the screen. On Linux systems and modern Unix system you no longer need the -print option at the end of the find command, so you can issue it like this:.

The -type f option here tells the find command to return only files. If you don't care about that, just leave the -type f option off your command. To search in the current directory — and all subdirectories — just use the.

The filename can end with any other combination of characters. It will match filenames such as Chapter , Chapter1 , Chapter1. These file locations are then printed to the screen:. Every option you just saw for finding files can also be used on directories.

Just replace the -f option with a -d option. For instance, to find all directories named build under the current directory, use this command:.

To find all files that don't match a filename pattern, use the -not argument of the find command, like this:. This next command shows how to find all files beneath the current directory that end with the extension. The -l argument to the grep command tells it to just print the name of the file where a match is found, instead of printing all the matches themselves:. Those last few characters are required any time you want to exec a command on the files that are found. I find it helpful to think of them as a placeholder for each file that is found.

This next example is similar, but here I use the -i argument to the grep command, telling it to ignore the case of the characters string , so it will find files that contain string , String , STRING , etc.

When these files are found, their permission is changed to mode rw-r--r This find command searches through the htdocs and cgi-bin directories for files that end with the extension.

When these files are found, their permission is changed to mode rwxr-xr-x. This example shows that the find command can easily search through multiple sub-directories htdocs , cgi-bin at one time:.

From time to time I run the find command with the ls command so I can get detailed information about files the find command locates. That's nice, but what if I want to see the last modification time of these files, or their filesize? No problem, I just add the ls -ld command to my find command, like this:.

The "-l" flag of the ls command tells ls to give me a "long listing" of each file, while the -d flag is extremely useful in this case; it tells ls to give me the same output for a directory. Normally if you use the ls command on a directory, ls will list the contents of the directory, but if you use the -d option, you'll get one line of information, as shown above. Be very careful with these next two commands. If you type them in wrong, or make the wrong assumptions about what you're searching for, you can delete a lot of files very fast.

Make sure you have backups and all that, you have been warned. Here's how to find all files beneath the current directory that begin with the letters 'Foo' and delete them. This one is even more dangerous. It finds all directories named CVS, and deletes them and their contents.

Just like the previous command, be very careful with this command, it is dangerous! For example, if you want to search for all files and directories named foo , FOO , or any other combination of uppercase and lowercase characters beneath the current directory, use this command:.

To find all files and directories that have been modified in the last seven days, use this find command:. The locate command keeps filenames in a database, and can find them very fast.

Last updated: October 18, The remaining sections on this page describe more fully the commands just shown. For instance, to find all directories named build under the current directory, use this command: find.

The -l argument to the grep command tells it to just print the name of the file where a match is found, instead of printing all the matches themselves: find. No problem, I just add the ls -ld command to my find command, like this: find.

10 find exec multiple commands examples in Linux/Unix

Prev Contents Next. Find is capable to perform several actions on the files or directories that are found with options -exec and - execdir the latter is "GNU find only" feature. At the same time it is a perfect tool to destroy your filesystem as option -exec blindly and very quickly executes commands you specified for the set of files provided by find.

If you want to search files by a pattern and then apply something to the results you have at least two choices. You can use find.

This is due in part to a complex syntax perhaps the most complex of all the standard Unix commands that aren't actually programming languages like awk ; and in part to poorly written man pages. The GNU version's man page didn't even have examples until late ! The very first thing you should do before you proceed any further is actually read your system's man page for the find command. You don't have to memorize it, or understand every part, but you should at least have looked at all the different parts of it once, so you have a general idea what's going on. Then, you might want to look at the OpenBSD man page for comparison.

UNIX for Dummies Questions & Answers

For years I always used variations of the following Linux find and grep commands to recursively search subdirectories for files that match a grep pattern:. However, I was just reminded that a much easier way to perform the same recursive search is with the -r flag of the grep command:. As you can see, this is a much shorter command, and it performs the same recursive search as the longer command. This next example shows how to recursively search two unrelated directories for the case-insensitive string "alvin":.

Linux find command provides a lot of features to search and filter files in file system. One of the most popular and useful feature of find command is exec option.

In Unix-like and some other operating systems , find is a command-line utility that locates files based on some user -specified criteria and then applies some requested action on each matched object. It initiates a search from a desired starting location and then recursively traversing the nodes directories of a hierarchical structure typically a tree. The possible search criteria include a pattern to match against the filename or a time range to match against the modification time or access time of the file. By default, find returns a list of all files below the current working directory , although users can limit the search to any desired maximum number of levels under the starting directory.

Use find to search for a file or directory on your file system. Using the -exec flag, files can be found and immediately processed within the same command. Use find from the command line to locate a specific file by name or extension. This command enables the maximum optimization level -O3 and allows find to follow symbolic links -L. The default configuration for find will ignore symbolic links shortcut files.

One of the really terrific things about the Linux find command is that you can combine it with the regular Linux grep facility. This lets you search for text strings and regular expressions in many directories at one time. The Linux grep command lets you search multiple files, so if you're looking for the proverbial needle in a haystack, you could issue a grep command like this:. This searches every file in the current directory for the pattern 'needle'. But if you want to search files in many different directories, that's where you need to combine the find and grep commands. First, if you want to perform a case-insensitive search, just add the "-i" flad to the grep command, like this:.

Jan 6, - of the following Linux find and grep commands to recursively search subdirectories for files that match a grep pattern: find. -type f -exec grep.

ГЛАВА 45 Дэвид Беккер бесцельно брел по авенида дель Сид, тщетно пытаясь собраться с мыслями. На брусчатке под ногами мелькали смутные тени, водка еще не выветрилась из головы. Все происходящее напомнило ему нечеткую фотографию. Мысли его то и дело возвращались к Сьюзан: он надеялся, что она уже прослушала его голос на автоответчике. Чуть впереди, у остановки, притормозил городской автобус.

Косые лучи утреннего солнца падали в башню сквозь прорези в стенах. Беккер посмотрел. Человек в очках в тонкой металлической оправе стоял внизу, спиной к Беккеру, и смотрел в направлении площади. Беккер прижал лицо к прорези, чтобы лучше видеть. Иди на площадь, взмолился он мысленно. Тень Гиральды падала на площадь, как срубленная гигантская секвойя.

Тайные операции. Джабба покачал головой и бросил взгляд на Сьюзан, которая по-прежнему была где-то далеко, потом посмотрел в глаза директору. - Сэр, как вы знаете, всякий, кто хочет проникнуть в банк данных извне, должен пройти несколько уровней защиты. Фонтейн кивнул.
