It is commonly used to verify the integrity of files. It (or a variant) is installed by default on most Linux distributions. Typically distributed alongside sha1sum are sha224sum, sha256sum, sha384sum and sha512sum, which use a specific SHA-2 hash function and b2sum, [1] which uses the BLAKE2 cryptographic hash function.

This is especially true of cryptographic hash functions, which may be used to detect many data corruption errors and verify overall data integrity; if the computed checksum for the current data input matches the stored value of a previously computed checksum, there is a very high probability the data has not been accidentally altered or corrupted.
cksum is a command in Unix and Unix-like operating systems that generates a checksum value for a file or stream of data. The cksum command reads each file given in its arguments, or standard input if no arguments are provided, and outputs the file's 32-bit cyclic redundancy check (CRC) checksum and byte count. [1]
File verification is the process of using an algorithm for verifying the integrity of a computer file, usually by checksum.This can be done by comparing two files bit-by-bit, but requires two copies of the same file, and may miss systematic corruptions which might occur to both files.
When To Use Kosher Salt vs. Table Salt "Kosher salt is a chef favorite because of the way you can easily grip it in your hands—with this built-in control, it is easier to season food more evenly ...
You could be paying more for a new Rolex watch at an authorized dealer — if you can find one in stock, Meanwhile, used Rolex prices fell across the globe, continuing a trend that began in 2022.
In the latter case, the use of a newer hashing tool such as sha256sum is recommended. md5sum is used to verify the integrity of files, as virtually any change to a file will cause its MD5 hash to change. Most commonly, md5sum is
