List all files with prepended CRC32 (or other) hash code?

I would like to list all files in a directory tree but with a prepended digest hash code (like CRC32). CRC32 is not a MUST. If suitable another hash code can be used as well. In case of CRC32 the listing should look like

3765AC \usr\bin\spool
23CE99 \usr\bin\spool\list.h
11AA04 \etc\apt\sources.list

How can I achieve this?

$ find . -type f | xargs crc32
8ffca073	./Dir1/file3
6734ef32	./Dir2/file4
2b985a52	./file1
ea7784a8	./file2

ea7784a8    ./file2

Thank you but this gives me (under Ubuntu 11.04) the following error:

xargs: crc32: No such file or directory

I assume crc32 and/or xargs is not available here.
Any other solution?

It's just a Perl script.

Ubuntu Manpage: crc32 - compute CRC-32 checksums for the given files

Use your Ubuntu package manager - whatever that is - to install it.

cksum does not give me crc32

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)
