I use quick and dirty greps all the time, even when there is a "better" option available. It just works and is very intuitive in interactive contexts. Probably GP works in a similar way.
- westurner 3y agoRemembered to add the `2>&1` stderr>stdout output redirection: ps wxa | grep <cmd> # or pgrep strace -f -f -e trace=file <cmd> 2>&1 | grep -v '-1 ENOENT (No such file or directory)$' Bash manual > 3. Basic Shell Features > 3.6 Redirections: https://www.gnu.org/software/bash/manual/html_node/Redirections.html https://www.gnu.org/software/bash/manual/html_node/Redirecti... In lieu of strace, IDK how fast `ls -al /proc/${pid}/fd/*` can be polled and logged in search of which config file it is; almost like `lsof -n`: pid=$$ # this $SHELL's pid help set; # help help (set -B; cat /proc/"${pid}"/{cmdline,environ}) \ | tr '\0' $'\n' (while 1; do echo \#$pid; ls -al /proc/${pid}/fd/*; done) | tee "file_handle_to_file_path.${pid}.log" # Ctrl-C It's good Configuration Management practice to wrap managed config with a preamble/postamble indicating at least that some code somewhere wrote that and may overwrite whatever a user might manually change it to (prior to the configuration management system copying over or re-templating the config file content, thus overwriting any manual modifications) ## < managed by config_mgmt_system_xyz (in path.to.module.callable) > ## </ managed>
