Sed - Substitution in a single line

Question

file.txt has only one single line :

110 ./blabla/log.txt

I would like to delete all data after 110. I tried

sed -e 's/\.\/b.*$//g' ./file.txt

It didn't work, why ?

Thanks.

it works fine to me. However, why not just `sed 's/ .*//' file` to remove everything from the space? — fedorqui, Oct 23 '15 at 14:26
Just pass `-i` to edit in-place (be careful with this option). — whoan, Oct 23 '15 at 14:26

There isn't a problem with the expression, but to do it inplace, you need:

sed -ie 's/\.\/b.*$//g' sed.txt

You could also simply by

sed -ie 's/ .*//g' sed.txt

However I suspect your example is actually not the real line in your file, perhaps you need to share this, there could be characters that your regex is missing.

there is no need for `$`. `.*` will match up to the end. – fedorqui Oct 23 '15 at 14:28
