I tried it via browser, but desn't:

UserName: name
FileName not_cleaned: juta_not_clean
FileName cleaned: juta

Text output test Error output test Query is: val_x=name&val_y=juta_notclean&val_z=juta Got variable val_x=name Got variable val_y=juta_notclean Got variable val_z=juta got XX=name YY=juta_notclean ZZ=juta

It's create file /tmp/juta_notclean.txt but don't create /tmp/juta.txt !!


My script.sh is like:

Code:
#!/bin/sh -f
echo "Content-type: text/html"
echo ""
echo '<html>'
echo '<head>'
echo '<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">'
echo '<title>Instance LOG's</title>'

#Step 1
echo "<form method=GET action=\"${SCRIPT}\">"\
     '<table nowrap>'\
         '<tr><td>UserName</TD><TD><input type="text" name="val_x" size=12></td></tr>'\
         '</tr></table>'
#Step 2
echo "<form method=GET action=\"${SCRIPT}\">"\
        '<table nowrap>'\
                '<tr><td>FileName not_cleaned</TD><TD><input type="text" name="val_y" size=12></td></tr>'\
                '</tr></table>'
#Step 3
echo "<form method=GET action=\"${SCRIPT}\">"\
        '<table nowrap>'\
                 '<tr><td>FileName cleaned</TD><TD><input type="text" name="val_z" size=12></td></tr>'\
                '</tr></table>'

echo '<br><input type="submit" value="Search">'\
       '<input type="reset" value="Reset"></form>'

# Make sure errors get shown in web browser.  DO THIS FIRST!
exec 2>&1

# Make sure web browser shows everything raw

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 -r "$XX" /opt/SUNWappserver/nodeagents/ins1/logs/ > /tmp/$YY.txt
echo "grep returned $YY.txt"
sed 's/INFO.*;|//g' /tmp/$YY.txt > /tmp/$ZZ.txt
echo "sed returned $ZZ.txt"

     echo '<br>'

echo '</body>'
echo '</html>'
exit 0

You have followed none of my suggestions. I suggest you follow them and tell me what happens then.

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
