I want to change how the line number is displayed
~$ echo a | cat -n
1 a
For example, I want it to be shown as
1:a
Although this can be easily done in anything other scripting language,
I'm wondering if there is an even easier way to get it done with cat.
$ echo a | nl -s: -w1
1:a
Option -s specifies which character to use to separate number and line.
Option -w specifies the width of the line number.
See the info page for nl for additional (formatting) options.
