sed : remove whitespace

b.hamilton · #1 (**permalink**) 11-06-2007

I'm trying to remove the whitespace at the end of each line of a text file in ksh.

Im using

sed s/ $//g' file1.txt > file2.txt

It's not working. Any clues?

Code:

sed 's/ $//'  file1.txt > file2.txt # Remove the last space at eol
sed 's/ $//g' file1.txt > file2.txt # Remove all spaces at eol

I don't think that will work. You need

Code:

sed 's/ *$//' file1.txt > file2.txt

Oups!

Code:

sed 's/ $//'  file1.txt > file2.txt # Remove the last space at eol
sed 's/ *$//' file1.txt > file2.txt # Remove all spaces at eol
