ZFS Snapshot Extractor

This is a simple Bash script to extract a specific version of a given file from ZFS snapshots. It must be started in the directory where the ZFS dataset is mounted. The relative path for the file must be given as parameter. It then displays a list of all files with a unique modification time time from the snapshots under .zfs/scnapshot and allows to select one (or several) to be copied to the user's home directory.

Example:

cd /tank/mydata
zfs-snapshot-extract.sh documents/report.txt
