ramdisksetup

A small utility / shell script to make a ramdisk (tmpfs).

usage

WARNING: this script needs root access. Please run with sudo.

ramdisk [-h] SIZE [PATH]

• -h: display help
• SIZE: size, for example 1m ( = 1MB) or 1G ( = 1GB)
• PATH (optional argument, default=/tmp/ramdisk): mountpoint for ramdisk

Make sure the directory you pass as PATH does not exist!

installation

Simply copy the ramdisk file into your $PATH, for example .local/bin/:

$ cp ramdisk ~/.local/bin/

You can also create a symlink:

$ ln -s full/path/to/ramdisk ~/.local/bin/ramdisk

Note: if that doesn't work, try chmod +x

examples

creating a ramdisk at the default mountpoint:

$ sudo ramdisk 1m
1m @ /tmp/ramdisk
* Mountpoint created
* tmpfs mounted!
Unmount with:
 sudo umount /tmp/ramdisk; sudo rm -rf /tmp/ramdisk

creating a ramdisk at a custom mountpoint:

$ sudo ramdisk 1m /mnt/tmp
1m @ /mnt/tmp
* Mountpoint created
* tmpfs mounted!
Unmount with:
 sudo umount /mnt/tmp; sudo rm -rf /mnt/tmp
