Readme for hstar-

[back to package description]


hstar is a command-line tool like tar, with several more features.


To generate bash shell completions:

hstar --bash-completion-script hstar


Unlike other tar implementations, hstar has the sanitize subcommand which converts a file into a pax-compatible archive and the lint subcommand which points out suspicious archives.

hstar can change the compression based on command-line flags, like bsdtar and arc (this feature is missing from GNU tar, busybox tar, and seemingly Schily tar).


hstar has near-parity with other command-line tar implementations with respect to compression support.

Program lzop lzip lzma gzip bzip2 zstd lz4 brotli snappy lrzip grzip
bsdtar x x x x x x x x x
hstar x x x x x x x x x ½
arc x x x x ½ x
Schily tar x x x x x x
busybox tar x x x
python3 tar module x x x
GNU tar x x x x x x


Benchmarks run on Linux. Performance should be near GNU tar, bsdtar, or Schily tar.
