cksum命令不识别-a选项
我正在尝试使用文件目录中的CRC32，SHA1和SHA256算法自动化校验和生成，并且根据CKSUM（v.8.32）的错误（v.8.32），
根据Cksum 手动在gnu.org上，它识别选项-a -a or or or 代码> - 算法可以从支持的校验和算法列表（包括SHA1，SHA256和CRC）中进行选择，但似乎无法正常工作。
命令：
cksum -a sha1 foo.txt
给出错误消息：
cksum: invalid option -- 'a'
Try 'cksum --help' for more information.
我尝试运行cksum - -help，但它仅打印以下内容：
Usage: cksum [FILE]...
or: cksum [OPTION]
Print CRC checksum and byte counts of each FILE.
--help display this help and exit
--version output version information and exit
GNU coreutils online help: <https://www.gnu.org/software/coreutils/>

or available locally via: info '(coreutils) cksum invocation'
它指向我的资源无济于事。
怎么了？有更好的方法吗？
I'm trying to automate checksum generation with CRC32, SHA1, and SHA256 algorithms on a directory of files, and I'm getting errors from cksum (v.8.32)
According to the cksum manual at gnu.org, it recognizes the option -a or --algorithm to choose from a list of supported checksum algorithms (including sha1, sha256, and crc), but it does not appear to be working.
The command:
cksum -a sha1 foo.txt
Gives the error message:
cksum: invalid option -- 'a'
Try 'cksum --help' for more information.
I tried running cksum --help, but it only prints the following:
Usage: cksum [FILE]...
or: cksum [OPTION]
Print CRC checksum and byte counts of each FILE.
--help display this help and exit
--version output version information and exit
GNU coreutils online help: <https://www.gnu.org/software/coreutils/>

or available locally via: info '(coreutils) cksum invocation'
And the resources it points me to are not helpful.
What is going wrong? Is there a better approach to take?

您需要gnu coreutils＆gt; = 9.0（即
cksum版本＆gt; = 9.0）这是版本9.0的ChangElog说：
You need GNU Coreutils >= 9.0 (i.e.
cksumversion >= 9.0)Here's what the changelog for version 9.0 says:
