9 | /* [date unknown. Perhaps before year 2000] |
10 | * To achieve a small memory footprint, this version of 'ls' doesn't do any |
11 | * file sorting, and only has the most essential command line switches |
12 | * (i.e., the ones I couldn't live without :-) All features which involve |
13 | * linking in substantial chunks of libc can be disabled. |
14 | * |
15 | * Although I don't really want to add new features to this program to |
16 | * keep it small, I *am* interested to receive bug fixes and ways to make |
17 | * it more portable. |
18 | * |
19 | * KNOWN BUGS: |
20 | * 1. hidden files can make column width too large |
21 | * |
22 | * NON-OPTIMAL BEHAVIOUR: |
23 | * 1. autowidth reads directories twice |
24 | * 2. if you do a short directory listing without filetype characters |
25 | * appended, there's no need to stat each one |
26 | * PORTABILITY: |
27 | * 1. requires lstat (BSD) - how do you do it without? |
28 | * |
29 | * [2009-03] |
30 | * ls sorts listing now, and supports almost all options. |
