Commands to find a file in Linux

The find command

The find command is used to find all the files that are present in the current directory.

For example :

If you want to find all the files present in the desktop directory then you just need to navigate to the desktop and fire the command find and this will show you all the files present in desktop.

~cd Desktop/

~/Desktop$ find .

The dot indicates the current directory.

If you know the approximate name of the file then The find command is also very useful. Because this command along with  -name argument is used to find the file related to specific characters.

You just need to navigate to the directory where you want to search a file then write the find command along with the approximate name and this command will show you all the files related to that approximate name.

The locate command

You can update the database when you want you just need to fire up the command sudo updatedb.

The locate command will give you all the files on the system that contains your search criteria fully matchable or partially matchable.

For example :

$ locate program

The locate command shows all the folder or the file that contains programs.

The which command

The which command is suitable for creating the shortcut of the program on the desktop.

Because this command will return the absolute path of executable.

~$which chrome


This command will only display the one matching executable. If you want to display all the executable then you need to add -an option with the command.

The  Whereis command

The whereis command is mainly used for finding where the binary, pages, and source files are located.

For example :

~$ whereis firefox

~$/user/bin/firefox/  etc/firefox  /user/share/man/man1/firefox.1.gz

If you don’t want the path of source and man pages and you only want the path of executable then you need to use the -b along with whereis.

For example :

~$ whereis -b firefox


If you only want the source then you need to add -s instead of -b and this will give you source pages.

If you want to locate only the man pages then you need to replace -b with -m.

For example:

~$whereis -m firefox

Basic Difference between which and whereis command:

  1. The which command is only able to show you the location of the binary for a given command while whereis command can show you the location of the binary, source, and the man pages for a command.
  2. The whereis command display all the things that it finds. While the which command only shows the first executable that it finds.

Determining the file type in Linux

The file command is used to determine the file type in Linux.

~$ file example.txt

~$ ASCII text

~$ file example.tar

~$ POSIX tar archive(GNU)

~$ file pictures/

~$ directory

~$ sudo du -sh /pictures

Result :

80GB     /pictures
