How to convert my /bin/sh script with cgi and html to run it on browser!??
Hello,

I want to run this script on my CentOS 6 via browser :
________________________________________________________________________________________________

Code:
#!/bin/sh
echo Username?
read MY_NAME
echo Provisional file name?
read MY_FILE
echo File NAME you want to save?
read MY_FILE2
cat /opt/SUNWappserver/nodeagents/ins1/logs/* | grep $MY_NAME > $MY_FILE.txt
sed 's/INFO.*;|//g' $MY_FILE.txt > $MY_FILE2.txt

________________________________________________________________________________________________


For that I have created 2 files : /var/www/html/test.html and /var/www/cgi-bin/script.sh:

1. I have created one file test.html
________________________________________________________________________________________________

Code:
<HTML>
<TITLE>LOGS</TITLE>
<BODY>
<b>LOGs Instacne</b><p>
<form action="cgi-bin/script.sh" method="post">
<br>
<input type="submit" value="LOG Button">
</form>
</BODY>
</HTML>

2. And /var/ww/cgi-bin/script.sh
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>Inscance LOGs</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>File Name 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>File NAME cleaned</TD><TD><input type="text" name="val_a" size=12></td></tr>'\
                '</tr></table>'

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

  if [ -z "$QUERY_STRING" ]; then
        exit 0
  else
     XX=`echo "$QUERY_STRING" | sed -n 's/^.*val_x=\([^&]*\).*$/\1/p' | sed "s/%20/ /g"`
     YY=`echo "$QUERY_STRING" | sed -n 's/^.*val_y=\([^&]*\).*$/\1/p' | sed "s/%20/ /g"`
     AA=`echo "$QUERY_STRING" | sed -n 's/^.*val_a=\([^&]*\).*$/\1/p' | sed "s/%20/ /g"`
     echo "UserName: " $XX
     echo '<br>'

     echo "File Not_Cleaned: " $YY
     echo '<br>'

     echo "File Cleaned: " $AA
     echo '<br>'


echo "cat /opt/SUNWappserver/nodeagents/ins1/logs/*" | grep $XX > $YY.txt

          browser="`echo $XX | cut -d\  -f1`"
          echo '<br>'
          echo "Browser: " $browser

BB="`echo $browser | sed 's/INFO.*;|//g' $YY.txt > $AA.txt`"
     echo '<br>'
     echo '<br>'
     echo "Result: " $BB
     echo '<br>'
fi
echo '</body>'
echo '</html>'
exit 0

________________________________________________________________________________________________


When I open in browser: localhost/test.html click on button "LOG Button" it redirects me on localhost/cgi-bin/script.sh.
I fill in the required fields and click on the search button to show the data, but the cat dhe sed command is not executed (echo "cat /opt/SUNWappserver/nodeagents/ins1/logs/*" | grep $XX > $YY.txt) and (sed 's/INFO.*;|//g' $YY.txt > $AA.txt).


Can you give me any suggestions to execute the script shell above in the browser and if i have chosen the wrong way how can i execute this script?

Regards,
Juta2020
