[ale] Question about scripting...

[scott mcbrien]

Chuck,
You really can't mix together several different languages in the same script
file.  What you can do is write one overarching script that then executes
scripts from other files.  So in the example you provide below, do something
like put your perl bits in another file, and have it take some files as a
command line argument.
 Also, if you want the perl script to run faster, perl has it's own
hostname and date functions, by embedding the shell call for hostname
and date you're having to create a bash process and execute the
`quoted` command for each instance of that command.  On one or two
short runs, probably not a problem, but for things like perl web apps
or other programs that are executed many times, that overhead adds up.

Best Regards,

Scott
