Git Alias: I thought this deserves it’s own little page.
Following will create an alias for git add, commit, and push
git config alias.acp '! acp() { git add . && git commit -m \"$1\" && git push ; } ; acp' Use it like this:
git acp "your commit message" Depending on your setup, you may also want to add git pull before you git add, but I am sure you can figure out how to do that.
Git Setup Remote Server Go to your web root directory
cd /var/www/ identify your self to git
git config --global user.name "Your Name" git config --global user.email "alias@example.com" Create git
git init Create a live branch
git branch live Make the live branch active
git checkout live Local Go to your working directory
cd /var/www/ identify your self to git
git config --global user.name "Dennis T Kaplan" git config --global user.

Linux Containers provide a Free Software virtualization system for computers running GNU/Linux. This is accomplished through kernel level isolation. It allows one to run multiple virtual units simultaneously. Those units, similar to chroots, are sufficiently isolated to guarantee the required security, but utilize available resources efficiently, as they run on the same kernel.
