Hello misc!
I'm in trouble with sed!
I need to insert tab in some places, but no luck :(
in linux it works:
[kasak@kasakoff ~]$ echo 'one two three' | sed s/two/\\ttwo/
one two three
in OpenBSD it just add t:
kasak@OpenBSD:~$ echo 'one two three' | sed s/two/\\ttwo/
one ttwo three
\t in the replacement string is not portable, it's an extension in GNU
sed (https://www.gnu.org/software/sed/manual/html_node/Escapes.html).
alternatives:
echo 'one two three' | sed -e "s/two/`printf '\t'`two/"
echo 'one two three' | perl -p -e s/two/\\ttwo/
or you can use a literal tab character, typed in many shells with ^V tab:
echo 'one two three' | sed 's/two/ two/'
Oh, thanks! I didn't know about that ctrl+v tab feature!
