'docker tail -n not showing correct no. of lines
If I run the following docker tail command:
docker logs --tail all 8f8df1de5f9c |& wc -l
645
It reports 645 lines
If I then run:
docker logs --tail 645 8f8df1de5f9c |& wc -l
550
It shows a reduced no. of lines.
I would have expected both commands to show the same no. of lines?
P.S. I'm writing unit tests so I need to know how many lines are available and then I need to run the command requesting exactly that no. of lines.
The docker version is:
docker --version Docker version 19.03.13, build 4484c46
I'm running on ubuntu 20.04 with a zfs file system.

If you want to read 250 line of file you must write this command
tail -n 250 pageName.blade.php
