I'd like to use sed to remove tabs from otherwise blank lines. For example a line containing only \t\n
should change to \n
. What's the syntax for this?
sed
does not know about escape sequences like \t
. So you will have to literally type a tab
on your console:
sed 's/^ *$//g' <filename>
If you are on bash, then you can't type tab
on the console. You will have to do ^V
and then press tab
. (Ctrl-V
and then tab
) to print a literal tab.
