Was wondering if you could help me figure this out.. I have a bunch of directories named d* and I'm trying to match them with a regex but for some reason it doesn't work..

Code:
$ ls
afile
bfile
donedir
dtwodir
ffile


Code:
for i in $(ls --color=none | egrep \md --colour=never)
do
cd $i
dosomething
done


Before I added the --color switch to ls, it did match fine but then the cd command didn't work, I presume because of the color output. So I added that and now it won't even match.

Try
Code:
ls --color=none | egrep ^d --colour=never

Code:
for i in d* ; do

Oh lifesaver, thanks a lot! I tried with ^ in the past but with the colors on it didn't work at the time, have been playing around with this for an hour now.

Gracias!
