Using
suggest changeYou can use the !$
to reduce repetition when using the command line:
$ echo ping
ping
$ echo !$
ping
You can also build upon the repetition
$ echo !$ pong
ping pong
$ echo !$, a great game
pong, a great game
Notice that in the last example we did not get ping pong, a great game
because the last argument passed to the previous command was pong
, we can avoid issue like this by adding quotes. Continuing with the example, our last argument was game
:
$ echo "it is !$ time"
it is game time
$ echo "hooray, !$!"
hooray, it is game time!
