nl without additional leading tab/space I notice that there is additional leading tab/space whenever `nl` is used. wolf@linux:~$ echo ABC ABC wolf@linux:~$ wolf@linux:~$ echo ABC | nl 1 ABC wolf@linux:~$ Is there any option to disable this? Desired Output wolf@linux:~$ echo ABC | nl 1 ABC wolf@linux:~$

Use `-w` option as following:


nl -w 1


to define custom separator:


nl -s '. ' -w 1


read `man nl` for explanation of the switches.
