Hi Greg I'm not sure what you lookin for but simpliest way is jsut to have the command after the if verb: if true then ... or if ls * then # true if there are any files You can also ask the $? after command execution /path/to/command if test $? -q 1 then .... or use case to handle differrent values /path/to/command case $? in 0) # success ... ;; 1) ?# minor failure ... ... esac HTH -- mr.
