Below csh script gives error: Undefined variable:confused:
#!/bin/csh
$QUERY="netscape";
COUNT_NETSCAPE=${ps | grep -c $QUERY};
echo $COUNT_NETSCAPE;
when run gives error
adroit:/home/seo/hitendra 64 ] ./unix_6.sh
QUERY: Undefined variable.
What is the root cause of the above problem ?
Remove $ from second line.
QUERY="netscape";
On removing $ it again gives error as below
adori:/home/seo/hitendra 70 ] ./unix_6.sh
QUERY=netscape: Command not found.
Variable syntax.
#!/bin/csh
set QUERY='netscape'
set COUNT_NETSCAPE=`ps | grep -c $QUERY`
echo $COUNT_NETSCAPE
