The 'adler32sum' command is an adaptation of the 'md5sum' command. It calculates ADLER32 checksums of files (or standard input). The ADLER32 checksum is the default checksum type used by SRM grid storage. This tool was developed for the DANS user community, as the "normal" 'adler32' command, which is part of the 'srmclient' package, does not support filenames containing spaces.
Advantages of this binary compared to the 'srmclient' "adler32" command
- small, tiny and fast C program
- exact same syntax as the 'md5sum' command
- can calculate checksums of multiples in one go
- supports spaces in filenames
'adler32sum' was developed as a minor patch to the 'coreutils-8.5' package which is part of almost all Linux distro's.
