  • How about Perl? Besides, the lock directory solution is available. Commented Jan 18, 2013 at 15:00
  • @sr_ Yes I do have Perl! For portability I am hoping to avoid dependency on external programs.. Commented Jan 18, 2013 at 15:09
  • Anyway, I'm rather confused about your question, since none of the answers in the referenced question uses flock... Commented Jan 18, 2013 at 15:13
  • @sr_ Sorry about that.. flock was mentioned in a comment. Commented Jan 18, 2013 at 15:19

    @sr_ and others: note that this question specifically asks about NFS. Many NFS implementations have race conditions that break many locking techniques. Solaris's NFS implementation is better than most, but please do not close this question as a duplicate of one that doesn't focus on NFS. Kent: are all the clients and the server running Solaris?
