How to replace spaces with commas?

[philthygeezer]

awk '{gsub(/,/," ");print}'

This will replace commas with spaces, but

awk '{gsub(/ /,",");print}'

Doesn't appear to do the reverse.

What do I do?

 

[PHV]

Perhaps this ?
awk '{gsub(/[ \t]/,",");print}'

or this ?
nawk '{gsub(/[ \t]/,",");print}'

Hope This Helps, PH.

Seems to work for me, what OS and version of awk?

$ echo "test is, allegedly, a test" | awk '{gsub(/,/," ");print}'
test is  allegedly  a test
$ echo "test is, allegedly, a test" | awk '{gsub(/ /,",");print}'
test,is,,allegedly,,a,test
$
