TR: Improvement for ls

[LAFARGE Jonathan (Cetelem)]

Hello,

 

I firsly wrote to   <mailto:address@hidden> address@hidden and Mr. Brett Smith
told me to write to  address@hidden <mailto:address@hidden> .

I have a suggestion : 

 

For ls, there could be an interesting option that would display the size of
each folder in ls -l mode.

For instance, instead of this :

 

% ls -l
total 152
drwxrwxr-x   25 user1    group1       8192 Mar 11 16:58 CETELEM

We could have this (with -s doing what I want) :

% ls -sl

total 27178816

It displays "???" when it can't go through directories to count size
(permission problems).

 

I created a shell script that do that, using du, but it's pretty slow (see
in attachment). I'm not competent enough to program it in the ls C code. So
I'm just sending you this idea, hoping that someone will develop it !

 

Hope I've been useful,

Regards,

Jonathan.
