I run your script via browser :
#!/bin/bash
# Make sure errors get shown in web browser. DO THIS FIRST!
exec 2>&1
# Make sure web browser shows everything raw
echo "Content-Type: text/plain"
echo
echo "Text output test"
echo "Error output test" >&2
echo
echo "Query is: ${QUERY_STRING}"
IFS="&=" ; set -- ${QUERY_STRING}
while [ "$#" -gt 0 ]
do
echo "Got variable $1=$2"
case "$1" in
val_x) XX="$2" ; shift ;;
val_y) YY="$2" ; shift ;;
val_z) ZZ="$2" ; shift ;;
*) ;; # Ignore unknown option
esac
shift
done
echo "got XX=$XX YY=$YY ZZ=$ZZ"
grep "$XX" /var/www/html/* > /tmp/a.txt
echo "grep returned $?"
sed 's/INFO.*;|//g' /tmp/a.txt > /tmp/b.txt
echo "sed returned $?"
The result is :
Text output test
Error output test
Query is:
got XX= YY= ZZ=
grep returned 0
sed returned 0
