tricky echo and return 1

[simanek]

I have some data that I need processed and in order to process it, it has to run through 3 scripts. These scripts are all modular enough where you just pipe the output from one to the next. So now, I want to get the result of this system("echo \"$var1, $var2\"" | script1.pl |script2.pl |script3.pl&quot statement and return it as html. Problem being is that 'system' returns error codes. Any ideas as to how to get this done? Thanks.

If you want to get the results of a system command passed back to your program, you should use backticks (

@results = `command`

) or open the command as a pipe and read it. I think the reason your system command is giving an error is because you've got a quote in the wrong place. You've got an extra quote after the echo statement that is closing the string to the system command, and another hanging quote at the end of the whole thing. If you've got quotes in a string it's much easier to use the qq generic quoting mechanism:

system(qq[echo "$var1, $var2" | script1.pl |script2.pl |script3.pl]);
