How to replace two or more spaces with one comma?
I'm using sh on hp-ux. I've got a file that looks like this.

Code:
-5.65   175
-16.17  160
-13.57  270
-51.72  260
-8.30   360
-42.71  460
-.38    375
-.20    375
-4.15   170
-21.53  560
-18.84  360

I'd like to replace all the whitespace between the columns with one comma. I can't seem to get the awk, sed, and tr examples I've found to handle the repeating spaces very well.

Thank you!

Code:
awk ' { print $1, $2 } ' OFS=, file

OR
Code:
awk ' { $1 = $1 } 1 ' OFS=, file

Shoot, why didn't I think of that?! Worked like a magic spell. Looks like I need to learn more about the Output Field Separator. Thank you!

Try this

Code:
bash-3.00$ cat sample.txt|awk '{print $1"\t"$2'}|tr "\t" ","
-5.65,175
-16.17,160
-13.57,270
-51.72,260
-8.30,360
-42.71,460
-.38,375
-.20,375
-4.15,170
-21.53,560
-18.84,360
