Confusing system call

mndoci has asked for the wisdom of the Perl Monks concerning the following question:

I am not quite sure if this is a Perl issue or a shell issue, but I have a script from an external source which works fine on Linux but not on AIX. I apologize if it is not a Perl issue. The error seems to be in the following system call

system("time $RUNHOME/$jobfile >& $RUNHOME/gcp_${FilName}_${total}.gs.
+out &");

Thanks
mndoci

That looks like csh syntax (the ">&" part). Change it to `system("time $RUNHOME/$jobfile > $RUNHOME/gcp_${FilName}_${total}.gs.out 2>&1 &");` ...but that shouldn't have worked anywhere as system command are not supposed to be run via csh. Oh well. - tye (but my friends call me "Tye")	[reply] [d/l]

Well on Linux I am on a t-shell, not a regular C-shell. On AIX I was on a C-shell. I am still having some shell-based trouble, but that is nto for this group.

>& redirects both stdout and stderr on some shells. time prints its output to stderr (this is useful because it allows you to redirect the program's stdout and just see the time info, but that's besides the point). You could try: `system("time $RUNHOME/$jobfile > $RUNHOME/gcp_${FilName}_${total}.gs.out 2>&1 &")` which should redirect both stdout and stderr to the $RUNHOME/gcp_${FilName}_${total}.gs.out file. Update Wow, must be smoking too much crack, I suggested the exact same thing that tye did and didn't even realize it.	[reply] [d/l]
