to-lzma − converts .Z, .lzo, .zip, .rar, .gz, and .bz2 files to zst format


to-zst [−(IPv)4] [−(IPv)6] [−d(elete_original)] [−h(elp)] [−k(eep_smallest)] [−m(ax_compress)] [−n(o_overwrite)] [−p num_cores] [−t(imestamp_retain)] file/URL...


to-zst recompresses files compressed with the compress, lzop, zip, gzip, and/or bzip2 utilities into zst format. The newly compressed files will usually have a .zst extension. If a specified file is actually a URL, it will be downloaded using wget and then recompressed.



Prefer IPv4 when downloading a URL.


−6 Prefer IPv6 when downloading a URL.


After each file is compressed, delete the original.


Print help and quit.


Once a file is successfully recompressed, delete the larger of the original file or the new one. This option maximizes disk space savings and is incompatible with the −d option.


Compress more, but at the expense of increased CPU time and memory usage.


Do not overwrite the target .zst file if it already exists.

−p num_cores

Use the multi-threaded -T option of zst to utilize multiple cores during compression. Note that the output file, while being fully compatible with unthreaded zst, will generally be slightly larger. Specifying a num_cores value of zero will utilize all available cores.


Make the timestamp of new files match those of the old files.
