How do i delete any sequence of trailing spaces & tabs at the end of the line in sed?
-
Man page for sed: https://www.lightnetics.com/post/3334
The sample file is:
cat -A nonprintchars This is my tab^I$ This is my space $ This is my$ ^M$ $ $ $
Use this, $ signs just denote the end of the line, they are not in the output normally, we only did tabs and spaces not newline character that's why you still see ^M
$ sed 's/[ ][^ ]*$//' nonprintchars|cat -A This is my$ This is my space$ This is$ ^M$ $ $ $
To delete the ^M as well do this:
sed -e 's/[ ][^ ]*$//' -e '/^M/d' nonprintchars|cat -A
