## Disks and Volumes
2015-09-22 17:23:45 -04:00
2015-09-24 12:11:34 -04:00
#### Disable Sudden Motion Sensor
Leaving this turned on is useless when you're using SSDs.
```bash
sudo pmset -a sms 0
```
#### Eject All Mountable Volumes
The only reliable way to do this is by sending an AppleScript command to Finder.
```bash
osascript -e 'tell application "Finder" to eject (every disk whose ejectable is true)'
```
2015-10-18 11:41:58 -04:00
#### Repair File Permissions
You don't have to use the Disk Utility GUI for this.
2015-10-13 14:02:56 -04:00
```bash
2015-10-18 11:41:58 -04:00
sudo diskutil repairPermissions /
2015-10-13 14:02:56 -04:00
```
2015-10-18 11:41:58 -04:00
> Beginning with OS X El Capitan, system file permissions are automatically protected. It's no longer necessary to verify or repair permissions with Disk Utility. ([Source](https://support.apple.com/en-us/HT201560))
2015-10-13 14:02:56 -04:00
2015-10-18 11:41:58 -04:00
#### Set Boot Volume

```bash
2015-10-18 11:41:58 -04:00
bless --mount "/path/to/mounted/volume" --setBoot
2015-09-25 10:40:55 -04:00
```
2015-10-18 11:41:58 -04:00
#### Show All Attached Disks and Partitions

2015-10-18 11:41:58 -04:00
### Disk Images
2015-11-05 14:26:08 -05:00
#### Create Disk Image From Folder Contents
2015-11-04 12:54:50 -05:00
```bash
2015-11-06 13:15:41 -05:00
hdiutil create -volname "Volume Name" -srcfolder /path/to/folder -ov diskimage.dmg
2015-11-04 12:54:50 -05:00
```
2015-11-06 13:15:41 -05:00
If you'd like to encrypt the disk image:
2015-11-06 13:07:16 -05:00
```bash
2015-11-06 13:15:41 -05:00
hdiutil create -encryption -stdinpass -volname "Volume Name" -srcfolder /path/to/folder -ov encrypted.dmg
2015-11-06 13:07:16 -05:00
```
2015-11-06 13:15:41 -05:00
By default, you'll be prompted for a password. You can automate that by piping in a password:
2015-11-06 13:07:16 -05:00
```bash
2015-11-06 13:15:41 -05:00
echo -n YourPassword | hdiutil create -encryption -stdinpass -volname "Volume Name" -srcfolder /path/to/folder -ov encrypted.dmg

defaults write com.apple.frameworks.diskimages skip-verify -bool true & & \
defaults write com.apple.frameworks.diskimages skip-verify-locked -bool true & & \
