getting Output of ls command in a file
Hi

I am trying to get the output of ls into a file with names seaparated with comma and no spaces.
Here is the content of my dir:

Code:
ls
file1        file2        file3        file4

this is what I tried:

Code:
ls -m > list.txt

the file 'list.txt' looks like:
Code:
file1, file2, file3, file4, list.txt

I want to get rid of the spaces, and also 'list.txt' should not be included.
The 'list.txt' I want should look like:

Code:
file1,file2,file3,file4

Thanks

Could you please explain me what the below code does?
Code:
's/,[^,]+$//'

"[^,]" matches characters that are not ",", so ",[^,]+$" matches last word (or any string of characters) in line, separated from others using ",".

Code:
ls -m | awk '$1=$1' FS=", " OFS="," > list.txt
