[ILUG] Life on a Linux box

[Nick Moffitt]

begin  Fiona Whelan quotation:
> 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,

	Since I open multiple shells, it even tells me that it isn't
that many *consecutive* hours.
