Thank you, I will do so from now on.

Thanks you, I will add more descriptive names in future. I didn't know $b
is a special internal variable used by Perl.

Wow, thanks!

This is acceptable, thank you!

Thank you, I definitely still need to familiarize myself better with
hashes and I
am working on getting there. From the likes of you and others in this
list I will
achieve this goal much quicker than just by myself.

This is really totally awesome, thank you so very much!
I really like what you have done with this line, it's very cool!
emcpowerbc sdb sdbe sddh sdfk emcpowerbc1 /s00_11 emcpowerbc2 /utl_file_dir
But, I plan to add things like "disk size", "disk size used" and
"disk size free" numeric values
next to each partition mount ( emcpowerbc1 /s00_11 ) and (emcpowerbc2
/utl_file_dir) in this case,
so I would prefer to have it like this instead:
emcpowerbc sdb sdbe sddh sdfk emcpowerbc1 /s00_11
emcpowerbc2 /utl_file_dir
or
emcpowerbc sdb sdbe sddh sdfk emcpowerbc1 /s00_11
emcpowerbc sdb sdbe sddh sdfk emcpowerbc2 /utl_file_dir
Could you please show me how to change your excellent code to achieve
either one of these instead?
Many thanks!
