Set git to use the credential memory cache:

git config --global credential.helper cache

To change the default password cache timeout, enter the following:

git config --global credential.helper 'cache --timeout=3600'
# (setting is in seconds)

To remove all untracked files:

git clean -df

For a specific file use:

git checkout path/to/file/to/revert

Edit the sudoers file:

sudo visudo

Find this line:

%sudo ALL=(ALL) ALL

To dump a filesystem into /mnt (a filesystem mounted on a seperate disk)…

cd /mnt
dump -L -0 -f- /path/to/origin | restore -r -f-

For remote operations, pipe the restore command via ssh:

dump -L -0 -f- /path/to/origin | ssh -2 -C -l remoteuser 192.168.0.2 restore -r -f-

Determine the file system by using the file-utility.

file image.img

Use mdconfig to link the IMG image to a virtual device.

mdconfig -a -t vnode -f /path/to/image.img -u 0
