Description Flags
Optimize noninteractive shell case, reduce amount of stat calls none

Description Ville Skyttä 2008-02-17 05:26:26 EST
Attached is a patch containing two optimizations for colorls.sh:

1) Don't do anything but set the "ll" and "l." aliases for noninteractive shells.
2) Avoid a bunch of stat calls whose results would just be thrown away.

The csh variant could seemingly use similar optimizations, but I'm not a csh
hacker so I'll leave it to someone else.

Thanks for optimizations. I used your patch with one change - aliases for
non-colored ls are kept inside the [ -z "$LS_COLORS" ] - doesn't make sense to
set them to non-colored and immediately to colored when LS_COLORS are set before
colorls.sh run. Will keep .csh script as it is, as is used much less than .sh
script. Built as coreutils-6.10-8.fc9 , closing RAWHIDE.

Yep, your change looks good.  When making the patch, in some of my intermediate
versions of it there was a chance that the "ll" and "l." aliases wouldn't be set
at all which is why I moved them to the top level, but that's clearly no longer
needed.  Thanks!
