2/8/2024 0 Comments Find file location linuxHere, we have applied the -P option to show the physical location instead of the symbolic link.įinally, we use the basename command to print the file name without a directory. Next, we print the current working directory using the pwdcommand. Then we change the directory using the cd command. Let’s create a simple shell script for the same: $ cat get_full_path.shĮcho "$(cd "$(dirname "$1")" & pwd -P)/$(basename "$1")"įirstly, we use the dirname command to find the directory in which a file is located. We can use the combination of these two commands to find the full path of a file. $ dirname /tmp/dir1/dir2/dir3/dir4/file4.txt Similarly, we can use the dirname command to strip the last component from the file name: $ basename /tmp/dir1/dir2/dir3/dir4/file4.txt Visit POWER TOOLS:A Very Valuable Find, by Jerry Peek, for creative ways to use find and important tips about constructing the command's options.The basename command is useful when we want to strip the directory and suffix from filenames. The ordering of find's options are important for getting the expected results as well as for performance reason. If the file is found it will be output to the screen and if the word "DOG" is found, within one of the found files, the line that "DOG" occurs in will also be output to the screen. It sends the files it finds to the grep command via the -exec option and grep searches the file found for any occurrences of the word "DOG". This sequence uses find to look in /users/home/directory/documents for a file ( -type f) with a name ending in. $ find ~/documents -type f -name '*.txt' \ One such combination would be using find and grep together. Without implementing a linker or using ldd, how can I find the full path to a libraryIs there a standard library available for that on Linux (POSIX maybe) Using ldd and grep on a file that is knowingly using libGL.so.1, it looks like: ldd /usr/bin/glxinfo grep libGL libGL.so.1 > /usr/lib/libGL.so. The power of findįind becomes extremely useful when combined with other commands. The "!" allows you to exclude results that contain the phrases following it. name '*foo*' ! -name '*.bar' -type d -print Several types of files can be searched for:ĭ door (Solaris) Search for directories that contain the phrase "foo" but do not end in ".bar" Similar criteria are -uid to search for a user by their numerical id, -group to search by a group name, and -gid to search by a group id number. The files output will belong to the user "joebob". $ find /some/directory -user joebob -print Search for files that are owned by the user "joebob" Search directories "./dir1" and "./dir2" for a file "foo.bar" bar, within the current directory and only search 2 directories deep You will now have a file ( confsearch) that contains all of the results from the find command issued. The 2>/dev/null option sends these messages to /dev/null so that the found files are easily viewed. For this, we’ll use the same example as above and pipe the results into a file called confsearch. When find tries to search a directory or file that you do not have permission to read the message "Permission Denied" will be output to the screen. $ find / -name foo.bar -print 2>/dev/null Find a file without showing "Permission Denied" messages "-mount" does the same thing as "-xdev" for compatibility with other versions of find. This can increase search speed greatly if the mounted filesystem is large or over a slow network. The find command does not need flags to search the files recursively in the current directory. This is useful if you have mounted network drives or filesystems that you do not want searched. Find a file without searching network or mounted filesystems Without specifications find searches recursively through all directories. On most platforms the -print is optional, however, on some Unix systems nothing will be output without it. If the file is found the path to the file will be printed as output. Examples Find a file "foo.bar" that exists somewhere in the filesystem The find command is a powerful *nix utility that allows the user to find files located in the file system via criteria such as the file name, when file was last accessed, when the file status was last changed, the file's permissions, owner, group, size, or even number of inodes.
