The 'newgrp' command spawns a new child shell. After that child shell exits the new group evaporates. The rest of the script continues with the previous id. This is a common misunderstanding of how newgrp works. People often think it changes the current shell. It does not. It stacks a child shell. Basically, newgrp does not do what you thought it did. It can't be used in this way. You might try having the newgrp shell read commands from a secondary file. newgrp group1 < other-script-file Or you might consider using 'sudo' or 'su' for that purpose too. Bob
