I have a file
~/foo.txt that has instances of each of the following strings
alpha-1 alpha-2 alpha-3 alpha-4 alpha-5 alpha-6 alpha-7 alpha-8 alpha-9
I would like to replace each of these
beta-X. Simply replacing
beta- will not suffice as there are other instances of
alpha- that I want to preserve.
I imagine this can be accomplished with something like
perl -p -i -e `s/alpha-SOMETHING/beta-SOMETHING/g'
but I'm not sure what
SOMETHING should be. Is there a solution here?
(Of course, I could run nine one-liners but this seems very inefficient.)
