can i perform an OR operation in sed syntax ?
if yes.. how?
I need to search for some 2-3 mail addresses in multiple files and delete all those... and instead of them.. I need to insert a new mail id...( these are also other emails in that list .. which sud not be affected )
is sed 'll be a good choice...??
or is there any other way to make it more effective...
Thnks
Are all those email ids in a single line ? Or one per line ? Will you replace all those 3 mail ids with just 1 mail id or will you replace each one with 1 mail id ?
If one per line, then
If it all-in-one-line or just scattered all over the place, then
