Adding a space between a match in Sed

That's an example of what I'm working with. I need to add a space after (COM|NET|INFO) so the domains are readable. I've tried a few different ways, but can't seem to get it to work. The regex should be (\.INFO|\.COM|\.NET) right?

sed uses POSIX Basic Regular Expressions, and use of alteration (|) in BREs is a non-portable extension.

In this case, to substitute for multiple words a substitution (s) command is needed per-word:

sed 's/\.INFO/& /g;s/\.COM/& /g;s/\.NET/& /g'

& is substituted for the entire match.

Though a more concise solution would be to use awk, which supports Extended Regular Expressions and, by extension, alteration:

awk '{gsub(/\.(INFO|COM|NET)/, "& ")}1'

Try to escape pipes in pattern:

sed 's/\(INFO\|COM\|NET\)/& /g' file
