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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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))
logging users for 10 minutes

hello i want to log all users my bot has scanned in channels for 10 minutes and then delete users log file 10 minutes later, is this possible?

The "standard" way to clean up old log files is to have a loop somewhere in your code that does your bookkeeping from time to time - you can't easily time it to run 10 minutes into the future, but you can have it look through all your log files when a user happens to (say) login, and delete all files that haven't been modified for over 10 minutes.

Here's some Tcl code that looks at all the files in a directory (in my example, called unjar), and reports on the age of each file.  For - err - obvious reasons, I have not replaced my puts statement with
if {$age > 600} {file delete -force $file}
while testing, but if you do it should be more or less what you want.  Beware - it is up to YOU (your risk!) to check out that my code does what you want - I am just providing a suggestion and can't be sure that it suits your needs.

The code:
Code:
foreach file [glob unjar/*] {
       set age [expr [clock seconds] - [file mtime $file]]
       puts "$file is $age seconds old"
       }
