💖 SHA384SUM(1) 💖 ok bestie let's talk checksums

so this one lives in the User Commands chapter of the manual, and it's part of GNU coreutils 9.12, and honestly? she's giving classic. let's go 🌸

✨ NAME ✨

sha384sum — compute and check SHA384 message digest 💅

✨ SYNOPSIS ✨

sha384sum [OPTION]... [FILE]...

✨ DESCRIPTION ✨

Print or check SHA384 (384-bit) checksums. she's a legacy interface to the cksum(1) utility, iykyk 🦋

With no FILE, or when FILE is -, read standard input. yep, the lil dash means "hey stdin, come here" 💌

okay so the options, bestie, one at a time, no skipping:

  • -b, --binary — read in binary mode
  • -c, --check — read checksums from the *FILE*s and check them
  • --tag — create a BSD-style checksum
  • -t, --text — read in text mode (this is the default, so she's the main character)
  • -z, --zero — end each output line with NUL, not newline, and disable file name escaping

The following five options are useful only when verifying checksums: — like, ONLY then, fr fr:

  • --ignore-missing — don't fail or report status for missing files
  • --quiet — don't print OK for each successfully verified file
  • --status — don't output anything, status code shows success
  • --strict — exit non-zero for improperly formatted checksum lines
  • -w, --warn — warn about improperly formatted checksum lines

and then the two classics that are always there for you:

  • --help — display this help and exit
  • --version — output version information and exit

the sums are computed as described in FIPS-180-2. When checking, the input should be a former output of this program. The default mode is to print a line with: checksum, a space, a character indicating input mode ('*' for binary, ' ' for text or where binary is insignificant), and name for each FILE. literally that exact shape, don't freestyle it 🙈

There is no difference between binary mode and text mode on GNU systems. so on GNU, -b and -t are lowkey the same girl 💀
