I need to replace all white spaces inside my text with commas. I'm currently using this line but it doesn't work: I get as output a text file which is exactly the same of the original one:
sed 's/[:blank:]+/,/g' orig.txt > modified.txt
thanks

With sed:
sed -e 's/\s\+/,/g' orig.txt > modified.txt
Or with perl:
perl -pne 's/\s+/,/g' < orig.txt > modified.txt
Edit: To exclude newlines in perl you could use a double negative 's/[^\S\n]+/,/g' or match against just the white space characters of your choice 's/[ \t\r\f]+/,/g'.

Thanks, however there is still an issue: I don't want to replace "next lines \n" with a comma, and the command with perl is currently doing it. She sed command you wrote, it still doesn't work. – aneuryzm Apr 22 '11 at 8:29

Sorry you need to escape the
+operator in sed, I just updated my answer. Newlines are whitepsace in perl, so you will have to do your whitepsace class manually if you don't wnat to include it. I added two solutions for that as wel. – Caleb Apr 22 '11 at 8:41

Using tr:
tr -s '[:blank:]' ',' <file
This will replace any horizontal whitespace with a comma. Any repeated whitespace will only be replaced with a single comma.

awk '{print $1","}' Servers | tr -d '[\n]' | xargs echo
Here the file name is Servers.. It contains the below content..
Server1
Server2
Server3
If we use the above command we can get the below output..
Server1,Server2,Server3,
[mohramak@oc3246038448 Desktop]$ cat Servers
Server1
Server2
Server3
[mohramak@oc3246038448 Desktop]$ awk '{print $1","}' Servers | tr -d '[\n]' | xargs echo
Server1,Server2,Server3,
[mohramak@oc3246038448 Desktop]$
