I'm frequently having to modify/convert email addresses from one
format/domain to another.
Usually, I slap together a quick Perl script to do this for me. I don't
do it frequently enough to keep track which one of my scripts does this
for me, so I'm continuously re-inventing the wheel.
Some of the time, I use sed/awk to do this, but that usually requires a
few passes over a few files.
To put it plainly, can anyone, if it's possible, provide a single line
sed/awk pipeline that can:
- read email addresses from a file in the format:
user.name TAB domain.tld
- convert it to:
- write it back to either a new file, the original file, or to STDOUT
