Hi! I'm new in scripting and I need some help with one simple script. I have to write a program that shows in a predetermined period (using "last" command), to draw up a list of users who have used the machine during this period. Each user to indicate how many sessions it has been during this period. Output must be sorted alphabetically by usernames (increasing alphabetically).
The code should be something like???:
But how to I predetermine the period and sort alphabetically(increasing)?
Regards,
Vassu

SLASRT
Purpose:
Sort the numbers in D in increasing order (if ID = 'I') or
in decreasing order (if ID = 'D' ).
Use Quick Sort, reverting to Insertion sort on arrays of

N
N is INTEGER
The length of the array D.
D
D is REAL array, dimension (N)
On entry, the array to be sorted.
On exit, D has been sorted into increasing order
(D(1) <= ... <= D(N) ) or into decreasing order
(D(1) >= ... >= D(N) ), depending on ID.
INFO
INFO is INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument had an illegal value
