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: .EX 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:

.EX mount -c /srv/infenv /n/ftp ls /n/ftp cat /n/ftp/emuargs echo masked man >/n/ftp/zorro /appl/cmd/9srvfs.b bind (1), srv9 (3), import (4)
