Hi --
Is there a way of detecting the exit code while calling system or pipe?
Yes, see the help page (you are ignoring the return value).
print(system("perl -e 'print \"foo\\\n\";exit(-1);'"))
foo
[1] 65280
(= 256*255)
eg (on Unix)
system("perl -e 'print \"foo\\\n\";exit(-1);'")
foo
Any help appreciated,
Ranjan
