Copy any directory to RAM (tmpfs) and automatically synchronize it with HDD.

Selected directory will be copied to tmpfs and replaced with symlink. Backup of directory will be created and placed in the same path to avoid data loss (backup will be restored automatically on next mount).

• realpath

This is a standalone script which doesn't need installation to work but it can be installed into system for easier access.

At the moment, there are three ways to install this script:

Dependencies:

• fakeroot

You can build .deb package using Makefile:

make deb

And then install it with dpkg:

sudo dpkg -i thedrhax-tmpfize-*.deb

You can copy tmpfize into /usr/bin using Makefile: sudo make install

Also you can uninstall tmpfize with sudo make uninstall

echo "deb http://local.thedrhax.pw/apt/stable/ /" | sudo tee "/etc/apt/sources.list.d/thedrhax.list"
wget -O- http://local.thedrhax.pw/apt/TheDrHax.key | sudo apt-key add -
sudo apt-get update
sudo apt-get install thedrhax-tmpfize

Command accepts one argument (path of directory that should be moved to tmpfs).

tmpfize [-hrvpu] [-t interval] SOURCE_DIR[.tar.gz] ... -- [COMMAND]

Options:

Technical:
 -h		        - Show help page.
 -v		        - Show info messages.

Mount Settings:
 SOURCE_DIR	    - Path or name of directory that will be moved to tmpfs.

 -t interval	- Synchronize interval in seconds (default: 30, 0 to disable).
		  
 -p       		- Do not delete directory from tmpfs after unmounting.
		  
 -r		        - Mount read only. Any changes in a tmpfs copy will not be
		          saved after unmounting. [DANGEROUS]

Execute scripts:
 COMMAND	    - Execute this command after moving directory to tmpfs.
	              When command is finished, directory will be moved back.

Mount control:
 -u		        - Unmount directory.

• Mount and unmount existing directory

# mount
tmpfize directory_name

# unmount
tmpfize -u directory_name

• Mount directory with disabled synchronization (directory will be synced after unmount)

tmpfize -t 0 directory_name

• Mount read-only directory (all changes will be lost after unmount)

tmpfize -r directory_name

• Start a custom script after mounting

tmpfize directory_name -- script_name

• Mounting a .tar.gz archive (since v1.3.0): archive will be unpacked to tmpfs and packed back after unmount

tmpfize directory_name.tar.gz

• Mounting multiple directories

tmpfize first_directory second_directory
