[9fans] rc shell script run by cron on linux

[Rudolf Sykora]

Hello,

I tried to run a cron job on linux using an rc script
and bumped into a problem.
When the job tries to be run I get something like

/usr/local/plan9/rcmain: rc (/home/sykora/plan9port/bin/
rc): .: can't open: No such file or directory

(I don't know why it starts with /usr/local...; but it is
probably not really relevant here.)

In my crontab I have specified a PATH containing
/home/sykora/plan9port/bin
(where rc itself is located)
but that seems to no be enough...
(If I hadn't I wouldn't have got to rcmain ever; so rc
calls for some reason rcmain [why? must it?])

Have anybody ever solved a problem like this?
(What is the minimum I have to have in order to
run rc script on linux?)

Thanks
Ruda

Just a guess but rc needs the bootstrap rcmain file, which it is looking
for in the default
directory, which is in /usr/local. I think if you set/export
PLAN9=/home/sykora/plan9port
as well as PATH, it might work.

Thanks, exporting PLAN9 at a suitable place seems to have helped.

Still, only if you can tell (I will test it at some point anyhow), is
1) rc binary
2) rcmain
3) suitable setting of PLAN9 variable
enough if you want to pass your rc script to somebody
who does not have p9p installed?
(Say, I wrote some rc scripts and now other people want
to use it...)

Thanks
