Re: [PLUG] Need some script advice

[Frank Szczerba <frank@szczerba.net>]

You could just wild card it like you do with the copy:

if [ -f *.zip ]
then
    echo 'Adding to archive'
    cp *.zip /Archive
    mailx -s "All good!" ...
else
    echo 'File not found!'
    mailx -s "Problem making archive! Come look" .....
fi

will work just fine if there's never more than one zip file present. If there might be more than one, you can do:

for zip in *.zip
do
    if [ -f $zip ]
    then
        echo 'Adding to archive'
        cp $zip /Archive
        mailx -s "All good!" ...
    else
        echo 'File not found!'
        mailx -s "Problem making archive! Come look" .....
    fi
done

This would be a bit more robust.
