remove file question

[stu78]

Hi,

To remove a file from within an awk script; can I use

cp /dev/null "file_to_rm.txt"

or

rm "file_to_rm.txt"

is there a better method to do this?

Stu:

you can use the system command to execute an external unix command. Myself, I think it's cleaner to remove files outside the awk script, but that's a personal choice.

cp /dev/null "file_to_rm" isn't really a delete, but it truncates the file to 0 size.

Regards,
