Loops in scripts

Here is an example of a simple loop in a script. I use it to send out my biweekly junkmail messages.[+]


    #!/bin/sh
    for i in `cat $HOME/jm/list`
    do
    mail -s 'Junkmail message number '$1 $i < jm.$1
    done

The script takes one line at a time from the file $HOME/jm/list and executes the command


    mail -s 'Junkmail message number '$1 $i < jm.$1

where $1 the first argument on the command line calling the script and $i is the line from the file $HOME/jm/list.
