Itried to do it recursively by checking if the current key is a hash and if yes call the current function again with refference to the sub hash.
Most of the printing seems to be OK but in... (1 Reply)

Hello!
For long I used cksum to find file duplicates in linux and darwin.
Now I want to make my own program that does all.
However I can't seem to find the correct algorithm.
zip and cksum claim to use the same algorithm, but the computated sums are not the same.

Is cksum the right command to calculate the crc32 checksum value? I tried it for a number of files now and every time the results dont match. So there is nothing wrong with the file. Also, cksum gives me an all numerical value while crc32 is alpha numeric. What am I doing wrong?
Thanks (9 Replies)

rdd-verify
VERIFIER(1) General Commands Manual VERIFIER(1) NAME
rdd-verify - verifies checksums and hash values generated by rdd-copy(1) SYNOPSIS
rdd-verify [OPTION] file1 ... DESCRIPTION
Rdd-verify verifies checksums and hash values generated by rdd-copy(1). Rdd stores checksums (Adler32 or CRC32) in files. These files must be passed to rdd-verify for verification. Hash values (MD5 or SHA1) computed by rdd-copy(1) must be passed to rdd-verify on the command line as hexadecimal strings. Rdd-verify reads all input files (file1, ...) and recomputes the checksums and hash values that the user wishes to verify. The verifica- tion will very likely fail if the concatenation of the input files is different from the source that was copied by rdd-copy(1). OUTPUT
All verification errors are reported on stderr. OPTIONS
-?, --help Print a usage message. -V, --version Report version number and exit. -v, --verbose Be verbose (more messages). -v, --verbose Be verbose (more messages). --checksum, --adler32 file Verify the Adler32 checksums stored in file. --crc, --crc32 file Verify the CRC32 checksums stored in file. --md5, --md5 digest Recompute the MD5 hash value. It should be equal to digest. --sha, --sha1 digest Recompute the SHA1 hash value. It should be equal to digest. A digest argument is a hexadecimal string. Leading zeroes may not be omitted. EXAMPLES
rdd-verify --md5 0123456789abcdef0123456789abcdef disk.img Compute the MD5 hash value over disk.img and verify whether it equals 0123456789abcdef0123456789abcdef. rdd-verify --adler32 checksums.a32 disk.img Compute the adler32 checksums over disk.img and compare each checksum to the corresponding checksum in checksums.a32.
