zb: that's going to be much slower.

wwes4, 1st one can be error, if there is many files on the tree.

Comment by zb 354 weeks ago

find ./backup -type f |perl -p -e 's/\n//;$l=$l+length($_); if ($l > 1024) {print "\nmd5sum ";$l=0};print " \047$_\047 ";$_=""' |sh

my long dirty version, prevent whitespacing, long commandlines

...or you could just use xargs -0, which works like a charm against any number of files (try it with find / if you don't believe it).

thanks! clear now.

If this is the wrong place for this request, please redirect me to the correct spot.

I'm new to Unix and took over a script that has the command "find . -type f -print | xargs -0 md5sum > md5sum.txt" in it. However it errors saying the '0' is an illegal option. How can I correct this command so it works again? I am on a Sun Solaris 10 system.

Would work better with an append redirect...

find ./backup -type f -print0 | xargs -0 md5sum >> /checksums_backup.md5
