For 2023 (and 2024 ...) - 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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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))
reading rc files

Reading from a dot file in current directory, OR from a system wide one, OR warning if neither exists.  No need to explicitly skip the loop if the  opens fail, since <FH> will return false straight away ...

open (FH,".myrc")
      or open (FH,"/etc/myrc")
           or warn("Using fallbacks\n");
while ($initline = <FH>) {

By the way

a) Files with names starting with a period (.) are silent or hidden files on Unix or Linux systems, only shown if you use an option such as -a to your ls command.   They will not be matched if you start an operating system command with a * (you must be specific about the .)  or Perl's glob function, but they will be returned to you by readdir.

b) rc stands for "runtime commands" if you wondered ... traditional, these are configuration files read by applications as they start up at run time - options not compiled into the executable.
