Shell script using sed or awk

[sudhanshu12788]

Hi, I want to read a file from the command line and remove all the spaces, tabs in it, replacing it with comma(,), and write it to a new file. can you help me out with this scenario.

Hi sudhanshu!

This should be relatively simple with a search/replace in sed. What have you tried so far?

[L7Sqr]

Using sed you can look for spaces and tabs [ \t] (extended regular expressions will allow modifiers to that). Then you can replace with a comma.
The general format of the sed search/pattern/replace is: s/PATTERN/REPLACEMENT/g I added the g on the end as it is a modifier to include all matches on a line, not just the first (something I think you want).

Refer to the famous sed one liners, I understand they're even maintained now.
