What is wrong here with sed?

Already spent a lot of time with the sed and gsed, by just trying to match a stupid string, but it still doesn't work!

neither:

echo "123adv123" | sed -En 's/\([a-z]+\)/#/g'

nor:

echo "123adv123" | sed -En 's/([a-z]*)/#/g'

nor:

echo "123adv123" | sed -En 's/([a-z]+)/#/g'

nor:

echo "123adv123" | gsed -rn 's/\([a-z]+\)/#/g'

nor:

echo "123adv123" | gsed -rn 's/([a-z]+)/#/g'

I'm trying it on the OSX. I know the question looks really strange, but I stucked and just want to get the glue what is wrong here?

The output should be 123#123

You need to remove -n otherwise it will suppress output.

This works on OSX:

echo "123adv123" | sed 's/\([a-z][a-z]*\)/#/g'

So is this:

echo "123adv123" | gsed -r 's/([a-z]+)/#/g'

Or this:

echo "123adv123" | sed -E 's/([a-z]+)/#/g'

Or to print only substituted lines use:

sed -nE 's/([a-z]+)/#/pg' file
