UNAME=os.arch to any "os.arch" you want 22 # to override the autodetetion. 23 # 24 # Usage: 25 # 26 # ssvnc_cmd [ss_vncviewer-args] hostname:N [vncviewer-args] 27 # 28 # if, instead, this script is named "tightvncviewer" or "-viewer" is the 29 # first argument it calls the vncviewer directly (there is no encryption) 30 # and must be invoked as: 31 # 32 # tightvncviewer [vncviewer-args] hostname:N 33 # or 34 # ssvnc_cmd -viewer [vncviewer-args] hostname:N 35 # 36 # In both cases, "hostname:N" is the host and VNC display to connect to, 37 # e.g. snoopy:0.
