NAME

crc - checksum files  

SYNOPSIS

crc file ...  

DESCRIPTION

For each file, crc 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. Crc uses a checksum compatible with the DOS version of crc, the 32 bit CRC used by PKZIP version 0.9, 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).

BUGS

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