coreutils: The cut command

 
 The ‘cut’ Command
 =================
 
 The next program we’ll look at is the ‘cut’ command.  This program cuts
 out columns or fields of input data.  For example, we can tell it to
 print just the login name and full name from the ‘/etc/passwd’ file.
 The ‘/etc/passwd’ file has seven fields, separated by colons:
 
      arnold:xyzzy:2076:10:Arnold D. Robbins:/home/arnold:/bin/bash
 
    To get the first and fifth fields, we would use ‘cut’ like this:
 
      $ cut -d: -f1,5 /etc/passwd
      ⊣ root:Operator
      ...
      ⊣ arnold:Arnold D. Robbins
      ⊣ miriam:Miriam A. Robbins
      ...
 
    With the ‘-c’ option, ‘cut’ will cut out specific characters (i.e.,
 columns) in the input lines.  This is useful for input data that has
 fixed width fields, and does not have a field separator.  For example,
 list the Monday dates for the current month:
 
      $ cal | cut -c 3-5
      ⊣Mo
      ⊣
      ⊣  6
      ⊣ 13
      ⊣ 20
      ⊣ 27
