Read arbitrary file via compression pipeline
bzip2 -c /path/to/input-file | bzip2 -dbzip2 compresses files using the Burrows-Wheeler algorithm. When used with sudo or SUID, it can read arbitrary files by compressing them to stdout and then decompressing. Related utilities (bzless, bzcat, bunzip2) also support privileged reads if bzip2 itself is SUID.
