Attachments:	Patch to implement -Q and -g adjust column width for multi-column ls -Q output

Description Andre Klapper 2009-01-15 11:19:32 UTC

Forwarding upstream from https://bugs.maemo.org/show_bug.cgi?id=3957 .

VERSION:
1.10.3

STEPS TO REPRODUCE:
In Busybox, enter
  ls -Q

EXPECTED OUTCOME:
quoted list of files. 
GNU "ls -Q" encloses filenames in double quotes.

ACTUAL OUTCOME:
  ls: invalid option -- Q
and the list of valid options

REPRODUCIBILITY:
always

OTHER COMMENTS:
-Q is not a posix standard option, but is quite popular and useful.
Many debian pre/post inst/rm scripts use this for things in /etc/init.d.

adjust column width for multi-column ls -Q output

A minor (I assume most consumers of ls -Q would be running it in single-column mode) issue is that in multi-column mode the column width isn't adjusted to include the quotes.  The attached patch is against 1.16.0.

Comment 4 Denys Vlasenko 2010-03-21 18:07:17 UTC

I don't see why it is needed. Without patch it already looks correct:

# ./busybox ls
AUTHORS                 busybox_ldscript        libbb
Config.in               busybox_ldscript_nobss  libpwdgrp
...
busybox                 init                    util-linux
# ./busybox ls -Q
"AUTHORS"                 "busybox_ldscript"        "libbb"
"Config.in"               "busybox_ldscript_nobss"  "libpwdgrp"
...

With -Q, columns become 2 chars wider. Right?
