Linux / Unix which Command Examples To Find Out A Program File

The which command is a utility that displays the location of a command or utility on a Unix or Linux system.

To use the which command, you can type which followed by the name of the command or utility that you want to find.

For example, to find the location of the ls command, you can use the following command:

which ls

This will display the location of the ls command executable on the system.

For example:

/bin/ls

The which command only searches for executables in the directories listed in the PATH environment variable. It does not search for man pages or other types of files.

If the command or utility is not found, the which command will display an error message.

The which command does not have any options, and simply displays the location of the specified command or utility.

For more information about the which command and its usage, you can consult the documentation for your specific Unix or Linux system.
