Fix get_binding_for(pid) for Rpreview #500

Closed lingceng closed 6 years ago

lingceng commented 6 years ago

:Preview can not get the right port on my Macbook. And I find out the lsof command gets the port name than the port number.

~/workspace/smart $ lsof -an -iTCP -sTCP:LISTEN -p23663
COMMAND   PID     USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
ruby    23663 lingceng   33u  IPv4 0xce7caf9daa1e02f5      0t0  TCP *:exlm-agent (LISTEN)

I add a -P option to fix it. This option inhibits the conversion of port numbers to port names for network files.

~/workspace/smart $ lsof -anP -iTCP -sTCP:LISTEN -p23663
COMMAND   PID     USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
ruby    23663 lingceng   33u  IPv4 0xce7caf9daa1e02f5      0t0  TCP *:3002 (LISTEN)
