The *very least* you could do is to state what you want the command to actually do. – Sven Apr 29 '13 at 12:16

Use brackets.
GID="gmod01"
PID=$(screen -list | grep $GID | cut -f1 -d'.' | sed 's/\W//g')
echo $PID

Dosent works... /restart: line 2: syntax error near unexpected token `|' ./restart: line 2: `PID=(screen -list | grep $GID | cut -f1 -d'.' | sed 's/\W//g')' – user2277716 Apr 29 '13 at 12:58
