Hi, Thanks for explaining the problem...I tried what you suggested. But still the system error is not displayed in html I tried to execute the script without cgi.

unless (`mkdir -p "/xyz/abc/test"`)
{
 die  "myerror $!";
}
[download]

Here is the output

mkdir: cannot access directory /xyz/abc/test.
/xyz/abc/test: Permission denied
myerror:  at ./testerror line 8

The part after myerror is the line number .
