Open the current project on Github by typing gh
Written for Mac OSX. When you are working in a project and want to open it on, just type "gh" and your default browser will open with the repo you are in. Works for submodules, and repo's that you don't own. You'll need to copy / paste this command into a file, then create an alias in your bash or zsh profile to the script. Detailed instructions here if you still need help:

remove files and directories with acces time older than a given date
touch a dummy file with the specified date, then use find with -anewer .

Know which version dpkg/apt considers more recent
Compares two versions with dpkg. It is not always obvious what version dpkg/apt will consider to be more recent. Operators include the following : * These treat an empty version as earlier than any version: lt le eq ne ge gt. * These treat an empty version as later than any version: lt-nl le-nl ge-nl gt-nl. * These are provided only for compatibility with control file syntax: < > >. This command doesn't output anything. It only returns with status 0 or 1, hence the echo "y" || echo "n" to get an output.

Command template, executing a command over multiple files, outputing progress and fails only
This is a command template for achiving the following: * loop over files --> find -name "" | while read file; do ...; done * output progress --> echo -n . * execute some command on each file and save output for later usage --> output=$() * if command failed, open subshell and echo newline --> || (echo;...;...;) * echo output of command --> echo "$output"
