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.
This should be relatively simple with a search/replace in sed. What have you tried so far?
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).
no every thing said is wrong please go ahed and let me know if you want any further information from me as senior scripting language progaramer
