putting an output from a terminal command to a file

fromvt · 10-11-2019, 11:14 AM

Hi,
I am trying to save error messages when compiling file "a.f" on my MAC using
gfortran as a FORTRAN compiler.

The terminal command
gfortran -c a.f > log

puts compiler errors on the screen rather than into the file "log". I have tried
both with existing and non-existing file "log"

There is no complaint about using the redirect sign ">". It simply ignores it.
Thank you in advance

Did you try with &> log ?

Your question is a duplicate of this thread.

Another option is to precede your activity with the script command, which mirrors all screen activity to a file until you terminate the script command with Ctrl-C.

Dear kermitdafrog8

Thank you very much. Your suggestion using "&>" for redirect worked

if you want to read some background info, look for stdin/stdout/stderr. You will find pages like this:
