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.

Move efficiently between directories. . This command adds a couple of extra features to cd, without affecting normal use. CDPATH use is also unaffected. It introduces and environment variable CDDIR which is used as an alternate home directory. . Note: I don't want to alter $HOME because then all my dot files will move. . Examples: .
cd dirChange directory to "dir" (using CDPATH if necessary) .cd dir/file.txtChange directory to "dir" (containing folder of "file.txt") This allows you to cut'n'paste, or use . CDDIR is unsetcdChange directory to $HOME . CDDIR=/home/flatcap/workcdChange directory to /home/flatcap/work . For convenience, put the command, and the following, in your .bashrc or .bash_profile export CDDIR="/home/flatcap/work" alias cdd="CDDIR=$(pwd)" Show Sample Output0cd() { if [ -n "$1" ]; then [ -f "$1" ] && set -- "${1%/*}"; else [ -n "$CDDIR" ] && set -- "$CDDIR"; fi; command cd "$@"; } -

Execute commands serially on a list of hosts. Each ssh connection is made in the background so that if, after five seconds, it hasn't closed, it will be killed and the script will go on to the next system. Maybe there's an easier way to set a timeout in the ssh options...
0for host in $MYHOSTS; do ping -q -c3 $H 2>&1 1>/dev/null && ssh -o 'AllowedAuthe ntications publickey' $host 'command1; command2' & for count in 1 2 3 4 5; do sleep 1; jobs | wc -l | grep -q ^0\$ && continue; done; kill %1; done -

Yes, it is not a command. Yes, you need to add it to your init script. Yes, you need to define $SH_ALIASES filename. But this shit can be very useful.
