Dumb Bash Script question

Am 25. May, 2011 schwätzte Dazed_75 so:

As Kevin already pointed out, use command substitution.

numlines=$( mount | grep tftpboot | wc | cut -c 5-8 )

In this particular case, you can shorten the pipeline.

numlines=$( mount | grep -c tftpboot )

You might even be able to just get the data directly from proc.

numlines=$( grep -c tftpboot /proc/mounts )
