--jRHKVT23PllUwdXP Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable This might be slightly off-topic, I suppose -- but since (t)csh is the default shell for FreeBSD, I figured this might be a good place to ask. I'm aware of the %T option for showing 24-hour time in my tcsh prompt, but it doesn't do exactly what I would like. Inserting a call to the date command so I can have the exact formatting I want appears to fail by only calculating the time once, and showing the same time every time the prompt appears -- which means that, several hours later, I'm still looking at the time from when the shell instance was started. The prompt setting using the date command that I used is as follows: set prompt =3D "[`date +'%H%M'`] %~%# " At nine in the morning, that gives me: [0900] ~> =2E . . whereas the tcsh native time formatting for 24-hour time is: set prompt =3D "[%T] %~%# " At nine in the morning, that gives me: [9:00] ~> I would prefer to not have the colon in there, but it's not a big deal. The biggest annoyance is the fact that the length of the time string changes depending on whether it's an AM time or a PM time. This is the best I've been able to get so far for a timestamp in the prompt that updates every time the prompt is displayed: [9:00] ~> This is acceptable: [09:00] ~> This is most preferred: [0900] ~> There must be some way to do this.
