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. Br, Erik
