  • human readable docker ps output

    When you run a lot of containers the built in docker ps output becomes unreadable. This command formats the output to be easier on the eyes. Requires q (https://github.com/harelba/q) text as data. Show Sample Output


    0
    docker ps | sed -e 's/ /\+/g' -e 's/CONTAINER ID/CONTAINER_ID/' | tr -s '+' '\t' | q -t 'select c1,substr(c7, 0, 40),c2,c6 from -' | column -t

  • Pretty print docker ps command

    If you have many port mappings, docker ps output becomes pretty illegible. The ~120 char one-liner changes the output into a more readable list of container! Show Sample Output


    0
    docker ps | perl -ple "s/\$/\n\n/g;s/\s{2,}/\n/g;s/(Up)/\\e\[32m\$1\\e\[0m/g;s/(Down)/\\e\[31m\\e\[5m\$1\\e\[25m\\e\[0m/g;s/^([^\n]+)/\\e\[1m\$1\\e\[0m/g;s/(\w+?)$/\\e\[4m\$1\\e\[24m/g" | more

  • 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.

    sudo docker rm $(sudo docker ps -q -f status=exited); sudo docker rmi $(sudo docker images -q -f dangling=true)

Check These Out

Get your external IP address without curl
Curl is not installed by default on many common distros anymore. wget always is :) $ wget -qO- ifconfig.me/ip

grep binary (hexadecimal) patterns
-P activates the Perl regular expression mode.

Use a var with more text only if it exists
See "Parameter Expansion" in the bash manpage. They refer to this as "Use Alternate Value", but we're including the var in the at alternative.

Tar files matching a certain wildcard
This is a shortcut to tar up all files matching a wildcard. Tar doesn't have the --include (apparently).

Scan a document to PDF
Adjust the --resolution and --mode as required (if these options are available for your scanner). The size options (-x, -y, -imageheight, -imagewidth) are for US letter paper. For A4, I think the command would be: $scanimage -p --resolution 250 --mode Gray -x 210 -y 297 | pnmtops -imageheight 11.7 -imagewidth 8.3 | ps2pdf - output.pdf

check open ports without netstat or lsof

convert markdown to PDF
This is the one-line version of this htmldoc + markdown combo to convert markdown formatted text to PDF files to distribute to your non-savvy project managers. http://scottnesbitt.net/ubuntublog/?p=114

execute command on all files of certain types excluding folders that match pattern

Display Spinner while waiting for some process to finish
alternatively, run the spinner for 5 seconds: timeout 5 bash -c 'spinner=( Ooooo oOooo ooOoo oooOo ooooO oooOo ooOoo oOooo); while true; do for i in ${spinner[@]}; do for j in seq 0 ${#i}; do echo -en "\b\b"; done; echo -ne "${i}"; sleep 0.2; done; done'

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
