> sed '/^[ \t]*$/d' does not work
Sorry guys, I just found out that
1. I probably missed the space inside the square brackets, and
2. I did not know I need to type a Ctrl-v before typing a real tab in
order for the shell to recognize the tab character
Now it works.
Further, sed 's/[ ]*$//'
where there is a space and a tab character between the [ and the ]
removes trailing spaces from each line.
How can I combine these two sed commands so that both empty lines and
trailing spaces (and tabs) are removed? Thanks.
