bashrc alias issue

noir911 · 08-22-2006, 03:34 AM

I have this alias in my .bashrc

alias burncd='cdrecord -v -pad dev=/dev/sdb $1'

it takes $1 as the file name to be burned. I was wondering how I could write it such that if someone forgets to give the name of the file, it will display "Error: please give the file name"

something like this -

$ burncd
Error: please give the file name to be burned.

You can use a function instead of an anlias:

Code:

function burncd {
    if [ ! -r "$1" ]
    then
      echo "Error: please give the file name"
      return 1
    fi
    cdrecord -v -pad dev=/dev/sdb "$1"
}
