This will make putting the image back onto the SD card faster and the shrunk images will compress better. -`Usage: sudo ./pishrink.sh [-s] imagefile.img [newimagefile.img]` +## Usage ## +`sudo pishrink.sh [-s] imagefile.img [newimagefile.img]` If the `-s` option is given the script will skip the autoexpanding part of the process. If you specify the `newimagefile.img` parameter, the script will make a copy of `imagefile.img` and work off that. You will need enough space to make a full copy of the image to use that option. ## Prerequisites ## If using Ubuntu, you will likely see an error about `e2fsck` being out of date and `metadata_csum`. The simplest fix for this is to use Ubuntu 16.10 and up, as it will save you a lot of hassle in the long run. +## Installation ## +```bash +wget https://raw.githubusercontent.com/Drewsif/PiShrink/master/pishrink.sh +chmod +x pishrink.sh +sudo mv pishrink.sh /usr/local/bin +``` + ## Example ## ```bash -[user@localhost PiShrink]$ sudo ./pishrink.sh pi.img +[user@localhost PiShrink]$ sudo pishrink.sh pi.img e2fsck 1.42.9 (28-Dec-2013) Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure
