How to change the bg color of chmod 777 directories in tcsh

colorcommand-line-interfaceshellslackware

On my MacBook Pro, I have iTerm and use the (black background) Pastel color set. World writable directories show up with a yellow background behind grey text. This I can live with, since the grey is dark enough to still be visible when surrounded by the muted yellow color.

But when I connect to my company's Slackware servers (via ssh and tcsh as my shell on the remote side), 777 directories show up as solid blocks of light green, as both bg and text color are identical (or close enough to make the text impossible to read).

How do I change the color used for the backgrounds of world-readable (777) directories?

Thanks!

I take it that this is output from ls, rather than tab-completion of shells? (I know at least one shell which can colourise shell tab-completions but you don't say, so I'll assume ls).

Use $LS_COLORS, often initialised via the dircolors(1) command. dircolors -p to see the defaults, take the output from the two systems and diff.

Drop the desired config into ~/.dircolors and then:

set d=$HOME/.dircolors
if ( -r $d ) eval `dircolors -c $d`

[modified from the info docs for dircolors invocation, in the coreutils package]

Linux – How to find the UUID of a filesystem

Another command that might be available and also works quite well for this is 'blkid'. It's part of the e2fsprogs package. Examples of it's usage:

Look up data on /dev/sda1:

topher@crucible:~$ sudo blkid /dev/sda1
/dev/sda1: UUID="727cac18-044b-4504-87f1-a5aefa774bda" TYPE="ext3"

Show UUID data for all partitions:

topher@crucible:~$ sudo blkid
/dev/sda1: UUID="727cac18-044b-4504-87f1-a5aefa774bda" TYPE="ext3"
/dev/sdb: UUID="467c4aa9-963d-4467-8cd0-d58caaacaff4" TYPE="ext3"

Show UUID data for all partitions in easier to read format: (Note: in newer releases, blkid -L has a different meaning, and blkid -o list should be used instead)

topher@crucible:~$ sudo blkid -L
device     fs_type label    mount point    UUID
-------------------------------------------------------------------------------
/dev/sda1 ext3             /              727cac18-044b-4504-87f1-a5aefa774bda
/dev/sdc  ext3             /home          467c4aa9-963d-4467-8cd0-d58caaacaff4

Show just the UUID for /dev/sda1 and nothing else:

topher@crucible:~$ sudo blkid -s UUID -o value /dev/sda1
727cac18-044b-4504-87f1-a5aefa774bda

Windows – On the fly text color change in Windows command prompt

On Windows XP this should do the trick. Download Tweak UI from Microsoft, then:

Start Tweak UI.
Click the "Command Prompt" link.
Check "Enable selection coloring".
Close Tweak UI.

This enables selection coloring on every command-line prompt. You should be able to highlight text, pressing CONTROL-0, CONTROL-1 (or any combination through CONTROL-9) to change the background color of the selected text. For changing the foreground color of the selected text, press ALT-0, ALT-1 (or any combination through ALT-9).
