For 2023 - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))

I have internal tool command when run against an user which gives the below result i wanna capture the the first field and third field with the max of third field (that is date)

command is :

system("intclmd | grep janab | grep 2007")

Client janab_test  2007/05/16  root C:\p4\testdep  'Created by janab. '
Client janab_prast 2007/8/16 root C:\p4\prastdep 'Created by janab. '
Client janab_crest 2007/7/16 root C:\p4\crestdep 'Created by janab. '

the result what i want is as the 2007/8/16 is the max in this case.
Client janab_prast 2007/8/16 root C:\p4\testdepot 'Created by janab. '

How can i get this perl.

Thanx in advance.

Run the command in backquotes and save it to a scalar, split the results at the new line character into a list, and loop through the list analysing each line in turn.  As the dates are in year/month/day format, you can simply remove the slashes and compare the numbers - though you will need to add code to handle the inconsistency of the number of digits in the month and perhaps day that you show in your example.
