sed special

Hi!

I have seen good documentation on internet for sed but nothing for this special issue

How to match a word in a sentence like this
Can you use sed for this?
Hello how are you
(2 spaces between words)

to

Hello how are you
(1 space between words)

Observe the spaces should be only between words not between characters!

Hi,

Can you explain your last sentence (only between words not between characters)?

Is this what you really want (by your last rule):

Code:

How  do  I  use  sed

becomes

How do  I  use sed

If all multiple spaces should be changes to 1 space (ignoring your last 'rule'):

sed 's/ [ ]*/ /g' infile

Hope this helps.

Code:

# more file
Hello  how     are     you
# awk '$1=$1' file
Hello how are you
