Re: "Auto Yes" to Warnings On Save (Scriptability)

The problem with using tail, sed, or similar is that they use intermediate files.  For the use case I'm describing, I need to be modifying the SAME file (same inode), because I'm trying to change a "live" file that the other process is writing to.  Living dangerously, I know.

Yes, I think tail is a much simpler option.  Just be aware you can't do this:

tail -n 25 myfile > myfile

... because the "> myfile" opens and truncates the file (throwing away the contents) before the tail command runs.

Something like this would work:

tail -n 25 myfile > /tmp/tail$$
mv /tmp/tail$$ myfile
