Hi,
in my "/etc/printcap", the "if" field points to an input
filter I wrote in Ruby. There, the first line is a shebang
saying
#!/usr/bin/env ruby
Further there is
# procstat -e `pgrep lpd`
PID COMM ENVIRONMENT
940 lpd PATH=/sbin:/bin:/usr/sbin:/usr/bin PWD=/ HOME=/ RC_PID=20
As you can easily see, I will receive a mail saying the
print job failed because of
env: ruby: No such file or directory
When I restart "lpd" from the command line, the new process
receives the environment variables from the shell process
and everything ist fine.
So far I found two ways to solve this neither of them I like
very much:
- Tweaking the PATH variable in "etc/rc" in the source
tree and reinstall by "make distribution".
- Patching the filter programms installation method to
modify the shebang line using "/usr/local/bin/ruby".
"/etc/crontab" allows to reset the PATH variable but I do
not see a way to do the same in "/etc/printcap".
Is there a better way to solve my problem and is there a
recommended one?
