    9) cat command- The 'cat' command is actually a concatenator but can be used to view the contents of a file.

    daemon:x:1:1:daemon:/usr/sbin:/bin/sh
    bin:x:2:2:bin:/bin:/bin/sh

    This command counts lines, words and letters of the input given to it.
    $ wc /etc/passwd
    35 57 1698 /etc/passwd
    12) grep command- The ‘grep’ command searches for a pattern in a file (or standard input). It supports regular expressions. It returns a line if it matches the pattern in that line. So, if we wish to find the lines containing the word ‘nologin’, we use ‘grep’ as follows:
    $ grep nologin /etc/passwd
    sshd:x:113:65534::/var/run/sshd:/usr/sbin/nologin
