Run shell using web
Hi,
I create shell script that can run using web browser.
The problem is when I put
echo "<pre> $(df -h) </pre>" I can see output in browser

But when I issue
echo "<pre> $(su - postgres -c 'SELECT * FROM .....') </pre>"
I can't see anything????

It seems the output from the postgre database is in tabular format which requires some formatting.
Try to put the following code snippet in your script
Code:
echo "Content-type: text/html"

I see, It seems that you have to loop through the output that came from postgre database table and and rebuild that table to be in html formatted table.

The answer as follows
1- Mainly it depneds on shell and html scripting skills , As I'm no scrpting expert
2- On your database table layout

I'll try to post when I find something that might suits your needs or just let us wait for someone to share his expertise with us.
