#   ConfigServer and Firewall › CSGet
#   
#   Script runs as a cron in:
#       /etc/cron.daily/csget
#       
#   By default, the script sleeps for a random number of seconds in
#   fork/daemon mode:
#       0 - 6 hours (rand(60*60*6) = up to 21600 seconds)
#       
#   After sleep, it connects to CSF api and gets the current ver of CSF:
#       https://download.configserver.dev/csf/version.txt
#       https://raw.githubusercontent.com/Aetherinox/csf-firewall/main/api/templates/versions/csf/version.txt
#       
#   After latest version is fetched from @downloadserver, a file is created in:
#       /var/lib/configserver/csf.txt
#   With contents like:
#       15.10
#       
#   If you run the script with the cmd below; a process is created with a random
#   duration between 0-6 hours.
#       sudo perl /etc/cron.daily/csget
#   
#   You can search for active copies of the process with:
#       ps aux | grep Config
#       root     3830870  0.0  0.1  22280  8980 ?        S    15:41   0:00 ConfigServer Version Check
#       sudo kill -9 3830870
#       
#   If you run the command below; action will immediately start with no lingering process:
#       sudo perl -d:Trace /etc/cron.daily/csget --nodaemon
#   All output will be logged to:
#       /var/log/csf/csget_daemon.log
#   
#   Requires:
#       DEBIAN/UBUNTU               sudo apt update
#                                   sudo apt install libdevel-trace-perl
#       REDHAT                      sudo yum makecache
#                                   sudo dnf install perl-Devel-Trace
#       
#   If you run the script using the cmd below; Action will trigger, 
#   create a child process, and wait 0–6 hours
#       sudo perl -d:Trace /etc/cron.daily/csget --debug
#   Logging will be sent to
#       /var/log/csf/csget_debug.log
#       
#   This script contains two log files:
#       /var/log/csf/csget_daemon.log     logs to this file if --debug mode DISABLED
#       /var/log/csf/csget_debug.log      logs to this file if --debug mode ENABLED
#   
#   @usage      sudo perl /etc/cron.daily/csget
#                   Runs the script normally, no extra warnings, no debugging.
#                   If the script forks (daemonizes), the parent exits normally.
#                   STDOUT/STDERR behavior depends on the script (e.g., closed in fork).
#       
#               sudo perl -w /etc/cron.daily/csget
#                   Enables warnings (-w flag) for uninitialized variables, deprecated
#                   features, or risky operations. Otherwise behaves like plain Perl.
#                   Fork/daemon behavior and STDOUT/STDERR unchanged (aside from warnings).
#       
#               sudo perl -d /etc/cron.daily/csget
#                   Runs the Perl debugger (-d). Stops at the first line and waits for
#                   debugger commands (n=next, c=continue). Can step through lines,
#                   inspect variables, set breakpoints, etc.
#                   Note: If the script forks, child processes won't have the debugger
#                   attached. Script behavior differs from normal run.
#       
#               sudo perl -d:Trace /etc/cron.daily/csget
#                   Special debugger module: Trace. Prints every line executed in real
#                   time. Useful for line-by-line debugging. Fork/daemonization can behave
#                   differently. Script may exit immediately or behave oddly as the
#                   debugger controls STDOUT/STDERR for trace output.
#       
#               Process can be killed with:
#                   ps aux | grep csget
#                   sudo pkill -9 -f "sudo perl -w /etc/cron.daily/csget"
