Reduce the number of key strokes to execute this command tar-t-v-f devfd0?

Answer 1

You could even shrink it more by doing:

tar -tf

the -v specifies verbose information. 99% of the time you don't care about that info.

And incase you don't know, -t doesn't really do anything, just displays the contents of the file specified with the -f.

if you want to extract it, you'll need to do -x

tar-tvf $devfd0

Q) tar -t -v -f /dev/fd0

A) tar -tvf $/dev/fd0
