crc - checksum files

ccccrrrrcccc file ...

For each file, _c_r_c calculates and prints a 32-bit CRC, the
byte count, and the file name. It is typically used to
validate files transferred between different systems, and is
useful in detecting subtle disk corruption. _C_r_c uses a
checksum compatible with the DOS version of crc, as well as
the "crc" command in ZCOMM and Professional-YAM (high
reliability communications programs).

The 32-bit CRC used is the frame check sequence in ADCCP
(ANSI X3.66, also known as FIPS PUB 71 and FED-STD-1003, the
U.S. versions of CCITT's X.25 link-level protocol).

Although most unlikely, files with different data may still
produce the same crc value.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read:
