[9fans] Where to set environments in p9p

[Hongzheng Wang]

Hi all,

I have a question about the settings in p9p (plan 9 from user space),
such as setting the default font ($font).

According to the documents, $PLAN9/rcmain and $home/lib/profile are
two places to put configurations stuff, say environments etc, which
would be read by rc shell when invoked by `-l' option.  But it is not
convenient if we use default shell, say Bash, instead of rc.

So, I wonder if there are some places to put these settings stuff so
that all p9p programs would read them when started.  Currently, I
added them in the script `9'.  I don't know if it is a good method.

Thanks.

 Wherever you want. The environment is not something p9p specific, and
how it gets initialised in somewhat dependent on your shell, OS, and
distribution.

 You're right, rc is beautifully simple compared to bash.
 It goes something like this:
 bash login shell: reads /etc/profile and ~/.bash_profile
 bash interactive non-login shell: reads ~/.bashrc
 bash non-interactive non-login shell: reads nothing unless you've set BASH_ENV.

 If you run /bin/sh instead of /bin/bash these rules totally change.
You'll find the details in bash(1) (maybe).

Thank you all, sqweek and arvindh :-)

I think the most convenient method, for me, is still modifying the 9
script and call p9p programs through 9 when necessary.  I said that is
due to my consideration: I hope I can stick with bash (I like its
readline support) and also play with p9p programs in almost all cases
(including sudo where the many non-standard configurations would be
ignored, say $PATH, by default).

To be specific, I add necessary settings in 9 script, and link it to
/usr/local/bin/9.  Then I can invoke p9p programs by 9 script, for
example, by `sudo 9 sam'.
