>Release: FreeBSD 2.2.7-STABLE i386
>Environment:
colorls from the ports collection (both 2.2.5 and 2.2.7).
>Description:
I have ls aliased to colorls -FG in my shell settings. This works well most of
the time but if I type, say ls | more I get the ANSI colour codes showing up,
ie I get ^[[31mcolorls*^[[m rather than colorls* in red. I assume more must fail
to print the escape character so the terminal dosn't interpret the code. I don't
know if that is a bug or a feature of more but I thought it would be nice to
have an option to colorls that only displayed colours if it was listing to a
terminal.
I used -K as -g was taken and it was close to -G. If anyone has a better letter
to use feel free to change it.
>How-To-Repeat:
colorls -G | more
>Fix:
The colorls port comes with one big patch file that patches everything in
one go but I did mine on a file by file basis so to incorporate them, either the
big patch will need to be split up into a patch for each file and my patches
used to replace the appropriate files or my patches will need to be copied and
pasted in with the others.
The patches were made in relation to the original ls source so they incorporate
asami@FreeBSD.ORG's original changes.
