NAME

crcman - checksum a directory

Specify the root of the directory tree to be checksummed. All files in all directories in the tree below that point will be processed.

DESCRIPTION

With the -b option, crcman will create a file of 32-bit CRC checksums for all files in the specified directory tree. For each file processed, the CRC file has a line with an 8-character hexadecimal checksum, a space, and the filename.

With just a single file name on the command line, crcman will verify the checksums of each file listed in the CRC file.
