Anything after this word is a "comment" for the file. so if you said ~/.bin/ls -al foobar and the file .comment existed, containing: foobar this is a comment the output would be: foobar this is a comment -rw--- 1 iain users 4668 2006-01-03 17:32 foobar You could then alias it, so instead of type ~/.bin/ls you could just type ls. -- Iain Buchanan A friend in need is a pest indeed. -- gentoo-user@gentoo.org mailing list

just for fun, I wrote this leedle script with my trusty glass hammer,
left handed screw driver, and can of 3mm holes. Call it "ls" and put it
in ~/.bin or something similar. It's not ideal but its a nice start if
you want to go further...
#!/usr/bin/perl -w
use strict;
my %files;
for my $i (0 .. $#ARGV) {
# print "$ARGV[$i] ";
if ($ARGV[$i] !~ /^-/) {
$files{$ARGV[$i]} = '';
}
}
# for my $i (sort keys %files) {
# print "'$i': '" . $files{$i} . "'\n";
# }
for my $i (sort keys %files) {
$files{$i} = [ `dirname $i`, `basename $i`];
chomp $files{$i}->[0];
chomp $files{$i}->[1];
# print 'file is ' . $files{$i}->[0] . ' ' . $files{$i}->[1] . "\n";
my $command = 'cat ' . $files{$i}->[0] . '/.comment 2>/dev/null | egrep "^'
. $files{$i}->[1] . ' "';
# print "$command\n";
print `$command`;
}
print `/usr/bin/ls @ARGV\n`;

Especially when other > programs are looking for the file names in a series. The simplest way I can see to do it, would be to: - make a bash script called "ls" - put it in your ~/bin directory (not in /bin) - make an alias to _your_ ls, which first checks for a descript.ion file or maybe even .comments file in the current directory, and then passes the rest to ls. A bit of fiddling, but that's what linux is about - if it doesn't work the way you want it: make it work the way you want it!!

Somehow, I still miss that feature. Additional comments would help me, for example, when I have a series of source code files with similar file names, and need to make comments to distinguish them.

While all of that is certainly true, it doesn't help you at all, if you wish to put a descriptive comment on a file. For example, it's a rather bad idea to rename /etc/passwd just to have a comment in the filename :) Yes, symlinks exist, but that's still not the same. No, I don't have an idea. Anything I can think of would require patching "ls". And I don't think that this would be a clever idea...
