Wireshark-users: Re: [Wireshark-users] Disabling "File Preview"

Is it possible to start wireshark on the particular input file directly (wireshark filename) ? You can then avoid the open dialog completely.

So I went through the excruciating exercise of installing the latest Wireshark
on my Ubuntu 9.04 system.  Very minor improvement, but it still tries to
'preview' everything in the directory.  IMHO, this is totally broken concept,
to say nothing of it's implementation.  Unless I'm missing it, even if I know
the name of the file I want to load, there is no way to type it in until the
complete directory scan completes.  Try that over NFS on a VPN with 200-400ms
latency -- argh!!

As for installation procedures... double argh!!  If the software wasn't
otherwise so essential for what I do, and in fact rather wonderful, I would
never have made it through.

Anyway, if there's magic to disable the 'stat' operation, like a pointer to a
file I can hack, please let me know.

Regards,
Jim
