vi part-pattern matching and deletion
Hi,
I have a log file which shows the files which has been changed over the last week.
They follow this pattern:
old_file_version_number@@new_file_version_number
Now I need to know how to delete from each line parts starting from @@.
I would be issuing the command inside vi(m).
So in the end the log file will contain just:
old_file_version_number
Thanks,
Vino
