Playing around with arguments

-

While writing shell scripts, we often need to use different arguments passed along with the command. Here is a simple tip to display the argument of the last command.

Use ‘!!:n’ to select the nth argument of the last command, and ‘!$’ for the last argument.

dev@home$ echo a b c d

abcd

dev@home$ echo !$

echo d

d

dev@home$ echo a b c d

abcd

dev@home$ echo !!:3 echo c c
