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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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))

suppose i have an input like

aaaa   bbbb    cccc
aaaa   bbbb    cccc
aaaa   bbbb    cccc
aaaa   bbbb   2cccc
aaaa   bbbb   2cccc
aaaa   bbbb    cccc
aaaa   bbbb    cccc
aaaa   bbbb    cccc

How can i remove the extra 2 from the 3rd column. Spacing n alll have to be fixed.
so i need to replace 2 with a space.

$line =~ tr/2/ /;

(there's a space between the final two slashes)
