Remove last ten lines of files

[Kuestner, Bjoern]

Hi,

does anybody have a simple solution to remove the last ten lines of files
(of variable length).

An alternative solution would be to remove anything from a file that follows
a signal pattern like "CutHere".

I looked at tail -10 and tail +10.
The first returns the last ten lines, the latter all but the first ten
lines.

I looked at head -10 and head +10.
Both return the first ten lines.

None of these returned all but the last ten lines.

I then thought about using "wc -l".
But the output, e.g. "   68 test.txt" does not allow arithmetic
interpretation.

Next I considered what I know about sed and grep.
Again nothing for the task.

I am not familiar with Perl, although a Perl solution would be acceptable.

Do I really have to build a long script for this seemingly simple task?

Thanks and regards,

Bjorn
