Re: [Sheflug] shell script challenge

[Denis Nikitin <dnn [at] xxxxxxxxxxxxxxxx>]

Cant see why not to use /bin/date with formatting
instead of putting names into array hardcoded.
say 
echo mylist_`date +%d_%B_%H.%M`.txt
will produce output:
mylist_24_July_19.57.txt
I am using such naming based on date for our db backup files (after do  
bzip2 --best to them).
Well obviously it's done from the cron-ed script - I am not do it 
manually :)
Best regards,
Denis.
