UNIX Special Characters
Any time I do :
Code:
ls *.txt > mytext.txt

I get something like this in the output file:
Code:
^[[0;32mCGRI0007.txt^[[0m*
^[[0;32mCGRI0008.txt^[[0m*
^[[0;32mCGRI0009.txt^[[0m*
^[[0;32mCGRI000.txt^[[0m*
^[[0;32mCGRI00.txt^[[0m*
^[[0;32mCGRI002.txt^[[0m*
^[[0;32mCGRI003.txt^[[0m*
^[[0;32mCGRI004.txt^[[0m*
^[[0;32mCGRI005.txt^[[0m*
^[[0;32mCGRI006.txt^[[0m*
^[[0;32mCGRI007.txt^[[0m*
^[[0;32mCGRI008.txt^[[0m*
^[[0;32mCGRI009.txt^[[0m*
^[[0;32mCGRI0020.txt^[[0m*

Code:
Tue Jan 22 16:19:19 EST 2013 x86_64 x86_64 x86_64 GNU/Linux
t1Fam_BrOv :~>alias | grep ls
alias l.='ls -d .* --color=tty'
alias lR='ls -R'
alias la='ls -Al'
alias lc='ls -ltcr'
alias ldd='ls -ltr | tail -10'
alias lk='ls -lSr'
alias ll='ls -l --group-directories-first'
alias lm='ls -al |more'
alias lr='ls -lR'
alias ls='ls -hF --color'
alias lt='ls -ltr '
alias lu='ls -ltur'
alias lx='ls -lXB'

Two questions:
1) Why do I get this.. what is.. contributing to this behavior.
2) how to get rid of this?

Can switch off color and try:
Code:
ls --color=never

Looks like your ls is emitting ansi terminal escape sequences even when not writing to a terminal. Your ls may be configured with --color or --color=always.

Yoda gave you directions on how to turn off color for a particular invocation of ls (assuming that you're using a Linux system).

To turn it off permanently for future invocations of ls, we need to know what OS you're using, whetter or not you have an alias in place for ls, whether the following variables are set in your shell's execution environment (LS_COLOR, CLICOLOR, CLICOLOR_FORCE, and LSCOLORS) and if they are set what values they have.

If the suggestions given so far don't help you correct the problem, please show us the output from the following three commands:
Code:
uname -a
alias | grep ls
set | grep COLOR

Maybe you have a setting for the PS1 variable (color prompt) that give this output.
Id did mess with my PS1 and did get lot of strange output.

I added the aliases, and yes, I do have COLOR.
