问题:

I am looking for a way to compute crc checksum cross platform.

cksum works on Linux, AIX, HP-UX Itanium, Solaris, is there a equivalent command of linux cksum in windows too?

%cksum run.sh
1491301976 652 run.sh

Note: no third party tool

In Windows (command prompt) you can use CertUtil, here is the syntax:

CertUtil [Options] -hashfile InFile [HashAlgorithm]

for syntax explanation type in cmd:

CertUtil -hashfile -?

example:

CertUtil -hashfile C:\myFile.txt MD5

default is SHA1 it supports: MD2, MD4, MD5, SHA1, SHA256, SHA384, SHA512. Unfortunately no CRC32 as Unix shell does.

It looks as if there is an unsupported tool for checksums from MS. It's light on features but appears to do what you're asking for. It was published in August of 2012. It's called "Microsoft File Checksum Integrity Verifier".

Here is a C# implementation of the *nix cksum command line utility for windows https://cksum.codeplex.com/

To avoid annoying non-checksum lines : CertUtil -v -hashfile "your_file" SHA1 | FIND /V "CertUtil" This will display only line(s) NOT contaning CertUtil
