Man find ignore directory

While trying to remember where I put it I realized I was going to have to do some case-insensitive file searching. I was happy to learn that both of my favorite Unix and Linux file-finding utilities support case-insensitive file searching. Both the find command and the locate command have command-line options that provide this support. It's easy to perform a case-insensitive file search with the Linux locate command: just add the -i flag. To search my entire filesystem for files and directories that contain the string typeahead , just use this command:. If for some reason you can't find your files with the Linux locate command, or your system doesn't have the locate command installed, you can also try searching with the traditional Unix find command.

mindepth and maxdepth in Linux find() command for limiting search to a specific directory.

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. For more details on the find command, check out our online version of the find man page. By Alvin Alexander. 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. Find and delete Be very careful with these next two commands.

Exclude a directory or multiple directories while using find command

This merges the file listing in the directory cache index with the actual working directory list, and shows different combinations of the two. Show only ignored files in the output. When showing files in the index, print only those matched by an exclude pattern.

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.

On Unix-like operating systems, the find command searches for files and directories in a file system. Within each directory tree specified by the given path s, it evaluates the given expression from left to right, according to the rules of precedence see " Operators ", below until the outcome is known. At that point find moves on to the next path until all path s have been searched. It can be used on its own to locate files, or in conjunction with other programs to perform operations on those files. The -H , -L and -P options control the treatment of symbolic links.

How to limit search a specified directory in Linux? It searches the directory tree rooted at each given starting-point by evaluating the given expression from left to right, according to the rules of precedence, 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 find command by default travels down the entire directory tree recursively, which is time and resource consuming. However the depth of directory traversal can be specified which are mindepth and maxdepth. Given below some examples to illustrate how depth of the directory traversal can be specified using mindepth and maxdepth. Reference : Linux manual page.

    Just that is necessary. Together we can come to a right answer. I am assured.
