Hey all,
I have written a script in bash that calculates the % of a person's life that they spend
connected to a linux box. It is rather long, so I was wondering what is the best way to go
about it.. probably something like perl can do it much quicker.
What the bash script does is this:
use the 'last' command to get login info for the user (supplied as argument to the script), cut
out the time bit using 'cut' (ie getting the brackets bit), cut the time bit into hours and minutes,
add up all the hours, add up all the minutes, and calculate total time.. all this work using 'expr'
in for..do..done loops, display this information as "accumulated hours" and finally express
this as a percentage of the time that has lapsed since their first login. Sound like a lot of
work? I did all this for fun! (yes, sad). I know perl has one-liners for a lot of things... but not for
this sort of thing, right? I am learning perl now and my first task is to re-write this bash script
in as few lines of perl as I can. Can anyone give me some pointers as to method?
Thanks,
_
