On aLinux machine (or a sufficiently old Solaris one) you could use lslk ,but it's never been ported to Solaris 10; instead you need to use ' mdb-k ', the kernel debugger.

The 'simple' command to get a list of files with file locks is:

Here is a modest suggestion for email clients: when you forward amessage, you should put some marker of this at the front of the Subject: header. Similarly, if you are configuring your email clientand you have a choice, you should set it up this way.

Once upon a time, hard disk transfer rates were an issue of seriousconcern. It mattered a great deal how fast your disks and their IOchannels could run, and changing technologies could have significantperformance effects; IDE versus SCSI and so on really made a difference.

For a lot of people, those days are long over. Disk interconnects areessentially irrelevant (for this) and streaming read and write bandwidthhas become if not irrelevant then generally not important. What matters,what limits performance, is seek time.
