9srvfs - add Inferno service to Plan 9 service registry
9srvfs [ -p perm ] srvname source
9srvfs is only usable (or indeed of interest) on Inferno hosted under Plan 9. It uses srv9 (3) to make an Inferno service source available to Plan 9 applications via the Plan 9 service registry. Srv9 (3) must previously have been bound to /srv in the current name space, with -c to allow file creation (see bind (1)).
Source may be either a command or the name of a directory. If source is surrounded by braces ({ and }), it is invoked as a sh (1) command, and its standard input (sic) is posted as Plan 9 service /srv/srvname with permissions perm (default: mode 600). Otherwise, source is taken to be a directory that is the root of a name space to export to Plan 9, an exporting file service is started (see sys-export (2)), and again posted as Plan 9 service /srv/srvname, and the export terminates when the Plan 9 service file has been removed and the last mounted instance goes away in Plan 9.
Make the current Inferno environment variables available to Plan 9 applications:
bind -c '#₪' /srv # if not already done
9srvfs infenv /env
The name space can then be mounted in Plan 9, allowing variables to be read and written in that Inferno environment:
mount -c /srv/infenv /n/ftp
ls /n/ftp
cat /n/ftp/emuargs
echo masked man >/n/ftp/zorro
/appl/cmd/9srvfs.b
