Hi
I believe there is a method to remove all temporary files when a KSH script terminates (either expectedly or unexpectedly).
I think is some sort of subroutine you can create that runs when the script exits. Can anyone help me with this please?
Many thanks

This is what I have so far and I'm sure that I'm missing things or have the wrong commands. I'm not sure where to go... (3 Replies)
Hello,
One of the senior network admins at work told me that I should not hard code temp files into my scripts. Rather I should use the mktemp commands in the script to create them on the fly.
His argument was that if a malicious user knew the name of my temp files in the script they could... (6 Replies)

Hi there,
As a regular unix user I am forever programming on the command line or writing scripts so that I first write a load of data to a file to read from. In the end I am always left with a bundle of .txt, .tmp which is what I usually call them. As a basic programmmer I was wondering is... (6 Replies)

Test::Trap::Builder::SystemSafe(3) User Contributed Perl Documentation Test::Trap::Builder::SystemSafe(3)NAME
Test::Trap::Builder::SystemSafe - "Safe" output layer backend using File::Temp
VERSION
Version 0.2.2
DESCRIPTION
This module provides an implementation systemsafe, based on File::Temp, for the trap's output layers. This implementation insists on
reopening the output file handles with the same descriptors, and therefore, unlike Test::Trap::Builder::TempFile and
Test::Trap::Builder::PerlIO, is able to trap output from forked-off processes, including system().
See also Test::Trap (:stdout and :stderr) and Test::Trap::Builder (output_layer).
CAVEATS
Using File::Temp, we need privileges to create tempfiles.
We need disk space for the output of every trap (it should clean up after the trap is sprung).
Disk access may be slow -- certainly compared to the in-memory files of PerlIO.
If the file handle we try to trap using this backend is on an in-memory file, it would not be availible to other processes in any case.
Rather than change the semantics of the trapped code or silently fail to trap output from forked-off processes, we just raise an exception
in this case.
If there is another file handle with the same descriptor (f ex after an "open OTHER, '>&=', THIS"), we can't get that file descriptor.
Rather than silently fail, we again raise an exception.
Threads? No idea. It might even work correctly.
