| Hi group, i need to create a shell script. The base of it is an excisting script. However I have very little knowledge about this. Can some please explain to me what this means: SENDER_ID=`echo $@ | awk '{print $12}'` SENDER_ID="SENDER_ID="$SENDER_ID eval $SENDER_ID AND if [ ! -r $SQL_EXT_PROG ] ($SQL_EXT_PROG = the call to a variable) So what does ! -r mean? Where can I find what parameters i can use, what's a good internet site? All help is greatly appreciated!! Regards, Visualsander |
