Today, I used grep to filter the git log output to only get the changes made on a certain value holding the version number for an app.
The git log output is sorted newest to oldest, but I was interested in how the changes progressed, that is, oldest to newest.
You can use tac to reverse a file or the standard input.
$ cat file.txt
a
b
c
$ tac file.txt
c
b
aHere's how it works when used with a pipe.
echo "a\nb\nc" | tac
c
b
a
