.dt/errorlog question

[DanNJ]

How does the system handle the rename and delete of the errorlog files? The reason I ask is because I am funning various scripts with set -x so that I can track them in the error log, now due to an increase in runs my errorlogs are growing too large. Is there a way to change how the system maintains these logs?

I wrote a scrip to do this:

Alternatively there's the very flexible GNU [g]logrotate[/b] tool which is available from

Quick question, in you script I see you put {} around your variables when you call them and that you double up on some other things like [[]] (())

any reason for this?

Both Bourne (sh) and Korn shell accept variables in ${this} format. It's safer to use because if the variable is followed immediately by some $othertext (and 'other' is the name of your variable) it won't be expanded, however if you use ${other}text it will.

[[ is the Korn shell version of [ and is built-in to the shell so is more efficient. It is also more powerful; you can use shell pattern matching.

((i=i+1)) for example is exactly equivalent to let i=i+1
