Hello, l'm a college student currently studying Linux. l'm messing up with the Coreutils scripts that you guys made. I figured how to run a BASH script separately using this syntax `./tests/cp/cp-HL.sh` after l call this command `export built_programs=cp` and use `echo $?` to check the exit code of the script. Now, I'd like to do the same thing with Perl script. However, when I execute it like l would with BASH script, like this `perl tests/misc/sort.pl` it shows some errors about `subroutine` not found or something. I notice the test Perl script depends on Coreutils.pm in the `/test` directory, but I do not know how to modify the test Perl script or the command syntax. I know to run any test separately, there is this command: `make check TEST='/test/misc/sort.pl' SUBDIR=. VERBOSE=yes` But that is not what I'm looking for.
I've been looking at the source code of Makefile, however, no progress. Thanks in advance, John Nguyen
