|
---|
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. 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 | *
|
---|
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?
