Erik Andersen | 9ffdaa6 | 2000-02-11 21:55:04 +0000 | [diff] [blame] | 32 | * 1. ls -l of a directory doesn't give "total <blocks>" header |
| 33 | * 2. ls of a symlink to a directory doesn't list directory contents |
| 34 | * 3. hidden files can make column width too large |
| 35 | * |
Eric Andersen | cc8ed39 | 1999-10-05 16:24:54 +0000 | [diff] [blame] | 36 | * NON-OPTIMAL BEHAVIOUR: |
| 37 | * 1. autowidth reads directories twice |
| 38 | * 2. if you do a short directory listing without filetype characters |
| 39 | * appended, there's no need to stat each one |
| 40 | * PORTABILITY: |
| 41 | * 1. requires lstat (BSD) - how do you do it without? |
