Summary
Compresses files using zstd
Description
The given files are compressed using zstd, and the original
uncompressed files are removed (by default). Files already compressed
using another method, are recompressed using zstd. If no files are
given, data from stadin is compressed and output to stdout
zstd is a fast compression method, at the default compression
level (8), it compresses and decompresses an order of magnitude
faster than gzip, while also providing substantially better
compression. At the highest compression levels, zstd can rival
bzip2/xz for compression, though it will then be substantially slower
at compression (than gzip). Decompression is allways fast.
Options
supports options:
- -k 0/1 (--keep)
- keep the original uncompressed file if 1 (default 0)
- -c number (--compressionlevel)
- number between 1 and 22 indicating compression level, where 1
= fast compression, 22 = high compression (default 8)
- -b number (--blocksize)
- number indicating the blocksize in Kb (default 512)
- -i 0/1 (--index)
- also create an zst index file
- -t number (--threads); number of threads used to compress
- -o filename (--outputfile)
- The compressed file will be written to filename. This
option can only be given if there is only one file given to be
compressed. You can send the compressed output to stdout by giving
- for filename. Unless the -keep option is explicitely given, using
-o will change the "default" for -k to 1.
