can't exucute a file in /tmp directory

[weiyuan-jiang]

Some users got issues when executing a file in the temporary directory.

GEOSgcm_App/gcm_setup

Lines 2606 to 2610 in 4ceccc3

	echo cat $LOCDIR/$FILE.tmp \| awk \'\{if \( \$1 \~ \"${string}\" \) \
	\{sub \( \/${string}\/ ,\"\#${string}\" \)\;print\} else print\}\' \> $LOCDIR/$FILE > $TMPCMD
	chmod +x $TMPCMD
	$TMPCMD
	/bin/rm -f $TMPCMD

I suggest to execute the command directly without writing to a file

echo cat $LOCDIR/$FILE.tmp | awk '{if ( $1 ~ "${string}" ) {sub ( /${string}/ ,"#${string}" );print} else print}' > $LOCDIR/$FILE

@weiyuan-jiang There might be a simple "fix" for discover (e.g., not NAS or local machines).

It turns out both LOCAL_TMPDIR and TSE_TMPDIR exist on login nodes! So, what we might just do is near the top of gcm_setup say "If discover, setenv TMPDIR=$LOCAL_TMPDIR".

Then, mktemp will use that and that does not have the noexec bit that /tmp has set.

For NAS, we'd need to think but then again, we've never really had this issues at NAS. But if we did, I can sort of think of ways to work around that even there.
