easily trace all Nginx processes

Nginx (and other webservers like Apache) can be awkward to trace. They run as root, then switch to another user once they're ready to serve web pages. They also have a "master" process and multiple worker processes. The given command finds the process IDs of all Nginx processes, joins them together with a comma, then traces all of them at once with "sudo strace." System trace output can be overwhelming, so we only capture "networking" output. TIP: to kill this complex strace, do "sudo killall strace". Compare with a similar command: http://www.commandlinefu.com/commands/view/11918/easily-strace-all-your-apache-processes Show Sample Output

Delete a certificate from the macOS security keychain

Use `security list-keychains` to find possible keychains, and `security dump-keychain` to look for certificates. `sudo security delete-certificate` without arguments shows options for removing: by common name or by SHA-1 hash. This is especially useful if a certificate locks up Keychain Access.app, which happens for certificates with many SANs in macOS 10.12. Found via: http://stackoverflow.com/a/16019443

Clear disk space by retaining only currently running Docker containers and only currently required Docker images.

Useful if your Docker host starts running out of disk space due to Docker debris. You should start by running "sudo docker ps" in order to check that all required containers are in fact running, and fix any that aren't before proceeding to the main event! "sudo docker rm $(sudo docker ps -q -f status=exited)" removes all containers which are no longer running. "sudo docker rmi $(sudo docker images -q -f dangling=true)" removes all Docker images not required for currently running containers.

Short Information about loaded kernel modules

I modify 4077 and marssi commandline to simplify it and skip an error when parsing the first line of lsmod (4077). Also, it's more concise and small now. I skip using xargs ( not required here ). This is only for GNU sed. For thoses without GNU sed, use that : $ modinfo $(lsmod | awk 'NR>1 {print $1}') | sed -e '/^dep/s/$/\n/g' -e '/^file/b' -e '/^desc/b' -e '/^dep/b' -e d

access to last touched or created file with arrow_up_key immediately after displaying the file list

Display recursive file list (newest file displayed at the end) and be free to access last file in the list simply by pressing arrow_up_key i.e. open it with joe editor. BTW IMHO the list of files with newest files at the end is often more informative. Put this 'lsa' function somewhere in your .bashrc and issue $ . ~/.bashrc or $ source ~/.bashrc to have access to the 'lsa' command immediately. . (the function appends command "joe last_file_in_the_list" at the end of command history)

Rename files in batch
