In the above example, you can generate a list of the machine names
(/path/clientlist.txt) on the fly with the following sed script.
The script is all one line even though the mailer will wrap it.

smbstatus | sed -e
"1,4d"  -e"s/^[^ ][^ ]*[ ][ ]*[^ ][^ ]*[ ][ ]*[^ ][^ ]*[ ][ ]*[^ ][^ ]*[ ][ 
]*\([^ ][^ ]*\).*/\1/"   -e '/^$/,$d'

By the way, the sed script reads,
1.  Delete the first 4 lines
2.  Throw away everything but the 5th word from each line.
3.  Delete all the lines after you hit a blank line (not counting the first
4
    which were already thrown away.
