| 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 |
Eric Andersen | 77d9268 | 2001-05-23 20:32:09 +0000 | [diff] [blame] | 12 | * (i.e., the ones I couldn't live without :-) All features which involve |
Eric Andersen | cc8ed39 | 1999-10-05 16:24:54 +0000 | [diff] [blame] | 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: |
Erik Andersen | 9ffdaa6 | 2000-02-11 21:55:04 +0000 | [diff] [blame] | 20 | * 1. ls -l of a directory doesn't give "total <blocks>" header |
| 21 | * 2. ls of a symlink to a directory doesn't list directory contents |
| 22 | * 3. hidden files can make column width too large |
| 23 | * |
Eric Andersen | cc8ed39 | 1999-10-05 16:24:54 +0000 | [diff] [blame] | 24 | * NON-OPTIMAL BEHAVIOUR: |
| 25 | * 1. autowidth reads directories twice |
| 26 | * 2. if you do a short directory listing without filetype characters |
| 27 | * appended, there's no need to stat each one |
| 28 | * PORTABILITY: |
| 29 | * 1. requires lstat (BSD) - how do you do it without? |
