xxhsum(1) -- print or check xxHash checksums
|
||
|
|
============================================
|
||
|
|
|
||
|
|
SYNOPSIS
|
||
|
|
--------
|
||
|
|
|
||
|
|
`xxhsum` [<OPTION>] ... [<FILE>] ...
|
||
|
|
|
||
|
|
DESCRIPTION
|
||
|
|
-----------
|
||
|
|
|
||
|
|
Print or check xxHash (32 or 64bit) checksums. When <FILE> is `-`, read
|
||
|
|
standard input.
|
||
|
|
|
||
|
|
`xxhsum` supports a command line syntax similar but not indentical to
|
||
|
|
md5sum(1). Differences are: `xxhsum` doesn't have text/binary mode switch;
|
||
|
|
`xxhsum` always treats file as binary file; `xxhsum` have hash bit width
|
||
|
|
switch (`-H`).
|
||
|
|
|
||
|
|
OPTIONS
|
||
|
|
-------
|
||
|
|
|
||
|
|
* `-c`, `--check`:
|
||
|
|
Read xxHash sums from the <FILE>s and check them
|
||
|
|
|
||
|
|
* `-H`<HASHTYPE>:
|
||
|
|
Hash selection. <HASHTYPE> means `0`=32bits, `1`=64bits.
|
||
|
|
Default value is `1` (64bits)
|
||
|
|
|
||
|
|
The following four options are useful only when verifying checksums (`-c`)
|
||
|
|
|
||
|
|
* `--strict`:
|
||
|
|
Don't print OK for each successfully verified file
|
||
|
|
|
||
|
|
* `--status`:
|
||
|
|
Don't output anything, status code shows success
|
||
|
|
|
||
|
|
* `--quiet`:
|
||
|
|
Exit non-zero for improperly formatted checksum lines
|
||
|
|
|
||
|
|
* `--warn`:
|
||
|
|
Warn about improperly formatted checksum lines
