Re: Calling system function in cgi

Instead of:

system("test.exe");
[download]

you can try using backtics:

my $results = `test.exe`;
[download]

The screen output of running test.exe will be captured in $results.

Although you're not doing it in your example, but if you pass any input from your CGI to the command line, make sure you untaint it first.

instead of using the backtics, i prefer qx Edit - after vek slapped me :-) Well, i prefer qx over backtics because it is more readable. my $result = `test.exe`; looks too similar to `my $result = 'test.exe';`. Using a qx instead signals that something special is happening here.	[reply] [d/l] [select]

While I'm sure you have your reasons for preferring `qx/STRING/` over `STRING`, perhaps it would help the OP if you'd expand on your reply a little and explain why. What benefits would the OP get from using one over the other? -- vek --	[reply] [d/l] [select]
