How to remove '^[[00m' in bash file?
Hi,

This should be a simple one: I run the following commands in bash and ksh respectively but got differenant results:
Code:
# ls -l /var/log > /tmp/a
# vi /tmp/a

In bash shell, I got:
Code:
^[[00mtotal 827364
-rw-r----- 1 root root            189 Aug  9 00:00 ^[[00macpid^[[00m
-rw-r----- 1 root root            132 Aug  9 00:00 ^[[00;31macpid.1.gz^[[00m
-rw-r----- 1 root root            224 Jul 10 00:00 ^[[00macpid.2^[[00m

In ksh, I got:
Code:
total 828552
-rw-r----- 1 root root            189 Aug  9 00:00 acpid
-rw-r----- 1 root root            132 Aug  9 00:00 acpid.1.gz
-rw-r----- 1 root root            224 Jul 10 00:00 acpid.2

How can I remove those "^[[00m" got in bash?

Thank you!

Better to just not make them in the first place. ls --color=never

ls ought to be intelligent enough to tell when it's not writing to a terminal and avoid escape sequences, unless someone forced it always-on through an option or environment var.

I don't think BASH had anything to do with it incidentally, except in that it would load a different profile than ksh does. Perhaps something in that profile forced color always-on.

Ok. I am going to check out the bash profiles. Thank you again!

it should be in .bashrc, and it should be alias ls='ls --color=auto', which should avoid printing out color codes to non-terminals.

It may also be in the LS_COLORS environment variable.
