Let us now see how to identify different file types in Linux.

One way to identify a file type is by making use of the file command.

$ file /home/michael
$ flle bash-script.sh
$ file insync1000.sock
$ file /home/michael/bash-script

Another way to identify a file type is by making use of the ls -ld command

ls -ld /home/michael
ls -l basg-script.sh
