How do you cksum a directory?
 
How can I checksum a directory?

Using both cksum and md5sum yields the same error

Code:
root@linux# cksum /bin
cksum: /bin: Is a directory
root@linux# md5sum /bin
md5sum: /bin: Is a directory
In Solaris 10 it works

Code:
root@solaris# cksum /bin
356121957      19968  /bin
How can I get the same fuctionality on Linux?

You can't. And on Solaris you're getting the cksum of the directory entry itself, not any of the file in it.

Okay I "solved this" by creating a function...

Code:
check_sum () {
  dir=$1 
  dirsum=0
  for sum  in $(find ${dir} -type f | xargs cksum | awk '{print $1}')
  do
    dirsum=$(( ${sum} + ${dirsum} ))
  done
  print ${dirsum}
}
And calling it in my script like so...

Code:
check_sum /bin
-C
