Hello everyone! For some strange reason, the variable outnow is ALWAYS empty! Even though the output of the gcc command outputed the output of its execution successfully on standard output...why is $outnow empty??
Code:outnow=`gcc -ansi -pedantic -Wall /home/psycho/Programming/Library/alphalib/etl.c $input -lm -lsfl` echo "This is output: $outnow" exit
Probably because error messages are written to stderr, not stdout.
Do you see the messages appear, despite your attempt to capture them?
This works for me
Code:a=`gcc prog.c 2>&1`
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
Yes! But it worked great, thank you Salem :]..... I so knew the 2>&1 technique!! Grrraaahh!! Think corey think!!Originally Posted by Salem
