------------------------
The file is a.out, it consist a set of logs from user access to my system ( email system)
question
--------------------------
using shell script, how can we extract 2 sets of IP output from the a.out log by separate the IP, determine human and non-human access base on rules of multiple same IP access within maximum 4 sec time.
the rules,
1) multiple same IP access that maximum time more than 4 second time = human
2) multiple same IP access within maximum 4 second time = non-human
output
-------------------
output should be in b.out and c.out
meaning
1) b.out = IP list with rule 1
2) c.out = IP list with rule 2
