UNIX Command Line

This is a small script to show how we can print the last command line argument passed to a script. Also printing the previous to last argument.


$ cat lcoml.sh
#!/bin/sh

eval last_arg=\$$#
echo Last Command Line Arg: $last_arg

((b4_pos=$#-1)); eval b4_last=\$$b4_pos
echo Previous to last arg: $b4_last


Executing:

$ ./lcoml.sh A 2 B 3.4 D
Last Command Line Arg: D
Previous to last arg: 3.4
