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.

Preview of a picture in a terminal

This command allows you to see a preview of a picture via the terminal. It can be usefull when you are ssh'ing your server without X-forwarding. To have en example of the output you can get with this command see http://www.vimeo.com/3721117 Download at http://inouire.net/image-couleur.html Sources here: http://inouire.net/archives/image-couleur_source.tar.gz

Open files in a split windowed Vim

-o acts like :spit. Use -O (capital o) for side-by-side like :vsplit. Use vim -d or vimdiff if you need a diff(1) comparison. To split gnu Screen instead of vim, use ^A S for horizontal, ^A | for vertical.

Do the last command, but say 'y' to everything

I doubt this works with other than bash, but then again, I havent tried. The 'yes' utility is very simple, it outputs a hell of a lot of 'y's to standard input. The '!!' command means 'the last command'. So this one-lines inputs a lot of y's into the last command, aggressively agreeing to everything. For instance, when doing apt-get.

Intercept, monitor and manipulate a TCP connection.

This will handle multiple incoming connections. Also, found sed works best with -u flag (unbuffered io). Easiest way I've found to get ncat is to install nmap.

Run entire shell script as root

Placing sudo in the shebang line of a shell script runs the entire thing as root. Useful for scripts designed to, e.g. automate system upgrades or package manager wrappers — makes prepending everything with sudo no longer necessary

Find out the starting directory of a script

Invoked from within a shell script, this will print the directory in which the script resides. Doesn't depend on external tools, /proc/self/*, etc.. (`echo` is a shell builtin.) To see the *current working* directory of a script, use `pwd`.

Calculate files' size

Print github url for the current url

Works for repos cloned via ssh or https.

apt-get upgrade with bandwidth limit

in Debian-based systems apt-get could be limited to the specified bandwidth in kilobytes using the apt configuration options(man 5 apt.conf, man apt-get). I'd quote man 5 apt.conf: "The used bandwidth can be limited with Acquire::http::Dl-Limit which accepts integer values in kilobyte. The default value is 0 which deactivates the limit and tries uses as much as possible of the bandwidth..." "HTTPS URIs. Cache-control, Timeout, AllowRedirect, Dl-Limit and proxy options are the same as for http..."

burn a isofile to cd or dvd

cdrecord must be installed. usefull alias: $alias burniso='cdrecord -v dev=/dev/cdrom' now iso burning is like. $burniso image.iso
