I was running a bash command similar to this:
perl /var/www/scott/perl/test/scott.pl --size 10 --file /tmp/output.txt
and afterwards I wanted to make a small change to that script. Rather than typing out the full path you can use some Bash history expansion and do this instead:
If you use
!: followed by a number, Bash will replace that with the Xth (starting at zero) parameter from the previous command.
