|
---|
[821] | 9 | * To achieve a small memory footprint, this version of 'ls' doesn't do any
|
---|
| 10 | * file sorting, and only has the most essential command line switches
|
---|
| 11 | * (i.e., the ones I couldn't live without :-) All features which involve
|
---|
| 12 | * linking in substantial chunks of libc can be disabled.
|
---|
| 13 | *
|
---|
| 14 | * Although I don't really want to add new features to this program to
|
---|
| 15 | * keep it small, I *am* interested to receive bug fixes and ways to make
|
---|
| 16 | * it more portable.
|
---|
| 17 | *
|
---|
| 18 | * KNOWN BUGS:
|
---|
[2725] | 19 | * 1. hidden files can make column width too large
|
---|
[821] | 20 | *
|
---|
| 21 | * NON-OPTIMAL BEHAVIOUR:
|
---|
| 22 | * 1. autowidth reads directories twice
|
---|
| 23 | * 2. if you do a short directory listing without filetype characters
|
---|
| 24 | * appended, there's no need to stat each one
|
---|
| 25 | * PORTABILITY:
|
---|
| 26 | * 1. requires lstat (BSD) - how do you do it without?
|
---|
[2725] | 27 | *
|
---|
| 28 | * [2009-03]
|
---|
| 29 | * ls sorts listing now, and supports almost all options.
