extra characters when using `ls *.*` in loops

[MCube78]

Hi, I am doing a script in tcsh (yes I know, I know..) and I have suddenly bumped into a problem I'm pretty sure I hadn't experienced up to now..

For various reasons I find the following type of loop very useful for my purposes:

foreach m (`ls folder/*.*`)
echo $m
something based on $m
something else based on $m
end

now, if I echo the variable to a file (i.e., echo $m >> test.txt) I can see that it's adding plenty extra characters plus a new line. Needless to say it jumbles up the "something based on $m" commands.

To give you an example, I have a folder (ROIs) with the following files in it

ROIs/csf_segm2func.nii.gz
ROIs/csf_segm.nii.gz
ROIs/gm_segm2func.nii.gz
ROIs/gm_segm.nii.gz
ROIs/wm_segm2func.nii.gz
ROIs/wm_segm.nii.gz

if I run the above loop echoing the $m variable to a file, and then `less` the file, here is what I get:

ESC[0mESC[01;31mROIs/csf_segm2func.nii.gzESC[0m
ESC[01;31mROIs/csf_segm.nii.gzESC[0m
ESC[01;31mROIs/gm_segm2func.nii.gzESC[0m
ESC[01;31mROIs/gm_segm.nii.gzESC[0m
ESC[01;31mROIs/wm_segm2func.nii.gzESC[0m
ESC[01;31mROIs/wm_segm.nii.gzESC[0m
ESC[m
test.txt (END)

In fairness, I use this sort of syntax real often and it's the first time it gives me this problem.

Any clues??

thank you

I suspect you have an alias for ls to turn on color display. You may want to unalias it before using.
Also, why not just do
foreach m (folder/*) ...
not sure why your using ls.
