Unique File Name for use in script

[Steve Bowman]

I am putting togeather a script to pipe an applications log data out to a file and do not want to overwright the previous output, I remember once using some form of $pid or something like that to include the cmd's pid as part of my output filename. Don't have time to go back and try to find that script.

any help would be great!

"$$" is your current pid so file.$$ (or whatever) is a unique file name.

On most systems you also have the "mktemp" command

I like to use the date command to create unique names, plus it keeps the file names in chronological order, for example:
cp logfile logfile`date =%y%m%d%T`

Sorry, that previous command should read
cp logfile logfile`date +%y%m%d%T`
