Oh.... don't I luv bashisms ... I slightly rewrote the program and will explain why
#!/bin/bash # -C just gives you a list of the processes called what are you doing which is more efficient than running multiple greps # In this case wc -l should always return at least one line since ps -C displays a header even when no processes exist cntr=$(/bin/ps -C whatareyoudoing | wc -l) #make sure cntr is not empty if [ "x$cntr" != "x" -a $cntr -gt 1 ]; then zenity --info --text "Call Logger Is Already Running" exit 1 fi while true do sleep 15m NOW=`date +"%Y|%m|%d|%H|%M|%S"` echo $NOW "|" `zenity --text "Attivita' :$NOW" --entry --title "X'Qed Tagħmel Man?" --width 1000 --height 5` >> $HOME/CALLOG & done exit 0 Did that help ?
