Something along the lines of:

[tt]for f in `grep -l ERROR logdir/*`
do
mailx -s &quot;ERROR found in $f&quot; address@domain < $f
done[/tt]

Annihilannic,

Can you try to explain what this script does ?

I dont really get the &quot;for f in .... &quot;

Thanks!

It's a 'for' loop that loops through the strings after 'in', setting the loop variable 'f' to that value.

For example, if you had:

[tt]for myvariable in one two three
do
echo $myvariable
done[/tt]

The output would be:

[tt]one
two
three[/tt]

In the script in my previous posting the backquotes ` around the grep command mean that the output of that command is put on one line and inserted into the command line at that position, so the for loop is looping through the list of filenames produced by grep -l.

In Korn shell you can use $(command) instead of `command` which works exactly the same but is a little clearer.

I hope that's clearer! Annihilannic.
