Reading files get stuck in bash

I am running this command on my log files,

grep "." file | tr '|' '\n' | sed -r "s/(.{3}).*?\.cpp/\1TRY/g" | tr '\n''|'

It runs as expected i.e. keeping the first three letters same to files with .cpp extension, adds TRY to it.

So if input is: abcdef.cpp

ouput is: abcTRY

(keeping words without extension as it is)

But is stops running(gets stuck) after some time, any suggestions on what might be the problem.

Remove the non-greedy quantifier.

sed -r "s/^(.{3})[^.]*\.cpp/\1TRY/"
