Include thousand separator in linux terminal

[Binary-Synapse]

Hello.

How can I include the thousand separator when I'm listing directory contents?
I would also like that setting to be system-wide.

So instead of this:

ls Documents -l
-rwxrwxrwx user user 123456789 Files.txt

I would like to obtain this:

ls Documents -l
-rwxrwxrwx user user 123.456.789 Files.txt

Thank you

At least, you can

$ ls -hl Documents
-rwxrwxrwx 1 user user 117M ... Files.txt

Hello,

Yes the 'h' switch is nice when you want to read it in 'human-format'.

But the purpose would be to include the thousand separator, to make it more easy to read the exact size of a specific file.

Then try

ls -log --time-style=+|sed -r 's/^[^ ]* *[^ ]* *//;s/ +/\t/;:l;s/(.*[0-9])([0-9]{3}[,\t])/\1,\2/;tl'

or, if your login shell is bash (would also work with ksh93, pdksh, or with any shell if using /usr/bin/printf from GNU coreutils)

ls -log --time-style=+|while read -r p l s n;do printf "%'15d %s\n" $s "$n";done

Hello.

It works.
Huge commands though...

Thank you schragge

Well, the first one may be shortened a bit if you don't mind all the other data you'll get with ls -l:

ls -l|sed -r 's/ +/\t/5;:l;s/(.*[0-9])([0-9]{3}[,\t])/\1,\2/;tl'

For the second, the following also should work, but it makes the command only marginally shorter

ls -log|while read -r p l s r;do printf "%'15d %s\n" $s "$r";done

FYI, the GNU coreutils 8.21 sport a new command numfmt, hopefully to be included in Ubuntu after raring.

Hi schragge

That really is a nice feature, to include in a near future.

I have always had trouble reading exact file sizes from Linux terminals.

Thanks for sharing.
