Need help with sed, the stream text editor

[BarryK]

Guys, does anyone know how to do this:

Code: Select all

echo "textA      textB" | sed -e 's///g'

The above line is incomplete.
What I want to do is detect "textA", one or more spaces, then "textB", and replace it with something else.
The something else, doesn't matter.
The problem is, how do I detect an arbitrary number of spaces?

Code: Select all

echo "textA      textB" | sed -e 's/textASOMETHINGHERE textB/replacement/g'

It's a regular expression thing probably, which I am weak at.

Code: Select all

echo "textA      textB" | sed -e 's/textA\W\+textB/REPLACEMENT/g'

\W =Whitespace (Spaces and Tabs)
\+ = one time or more
