why to commit .cshrc "source .cshrc" file in every new shell session

Hello Everyone,

Some of my problems i'm facing in linux.

1. I'm new to linux environment and recently i installed mandriva 08 and i configured the .cshrc file then used source to commit changes but whenever i open new shell/shell tab/shell session i have to use source .cshrc to commit everytime. And if i do not use source in new shell session and try "echo $JAVA_HOME" then it doesn't shows the path of environment variable JAVA_HOME.

2. mp4 video file not working properly. video is ok but audio not ok. No audio in .mp4 file. I know it has been asked before in this forum but i didn't got it cleared why it happens? as it was working ok when i previously installed mandriva.

Thanks,
simer

Hi. 2008 is fairly old, in Linux years, so that's a bit puzzling but bash has been the default shell as long as I have used Mandrake -> Mandriva.

Code:

[rolf@localhost ~]$ echo $SHELL
/bin/bash

I can imagine, if you are, also, using bash, that you ought to be editing .bashrc, instead.

Also,

Code:

[rolf@localhost ~]$ which csh
/bin/csh
[rolf@localhost ~]$ ll /bin/csh
lrwxrwxrwx 1 root root 4 2009-05-11 08:27 /bin/csh -> tcsh*

The actual program being used for csh is tcsh, so that might introduce complications, iow, I might expect .tcsh to be the name of the profile file.

For the video files, I am not an expert but there are codecs and capabilities that can't be distributed by Mandriva due to licensing and/or legal considerations, so some things only work with third-party applications, such as from PLF: http://plf.zarb.org/packages.php

Code:

[rolf@localhost ~]$ rpm -q mplayer win32-codecs libdvdcss2 smplayer
mplayer-1.0-1.rc2.23.r28791.2plf2009.1
win32-codecs-1.9-1plf2009.0
libdvdcss2-1.2.10-1plf2009.0
smplayer-0.6.7-1mdv2009.1

I am playing, atm, a .mp4 file in smplayer, with video and sound.
This is in 2009.1 and development is dynamic. There could be other factors.

Hello Rolf,

I actually changed my shell from bash to csh.So in that case i'll be using .cshrc file only.

Well, thanks about mp4 support.

Thanks,

Did you look at the manual? I don't see what is needed but there is a lot of info there.
man csh
