Yeah. The history mechanism in tcsh doesn't cope very well with multiple=
=20
ttys being closed down at once, as you tend to find when logging out of a=
n
X session. You get the history from just one of those shells.=20
It's not a complete cure, but telling the shell to merge it's history wit=
h
what's already there:
set history =3D 500
set savehist =3D (1000 merge)
This helps, but it is not completely reliable when several shells are shu=
tdown
in quick succession.
Cheers,
