i have directory dira on laptop, , directory dirb on remote host can ssh . both directories include subdirectories. i compare full content of 2 subdirectories using ssh. in particular, want know file or subdirectory in dira not in dirb, , other way around. 2 directories large enough not want transfer full files through ssh , compare names , locations. do know how this? thank you. use rsync --dry-run option; like: rsync -ar --dry-run local-dir/ user@remote:remote-dir this output list of files would have been synchronized . if there no output; there no difference. edit : 2 options might consider: --ignore-times : ignore timestamp of local , remote files when comparing files. --size-only : if want speedup rsync command. rsync compares size of files. note error prone (files same size might differ) --itemize-changes : show changes between files you may take @ this anwser

i use web socket between raspberry pi , server , works perfect, theory of web socket. but when search web socket arduino found lot of libraries , may of them http post not real web socket. send posts , receive gets, web socket open connection between 2 terminals , send posts , wait message other side. in arduino application need send http requests know state of led server, leads traffics, when using web socket server sends message arduino when state changed, , arduino waits message. does 1 know real web socket library arduino? there no "real" websocket library arduino. i recommend using raspberry pi farther arduino because more stable arduino since has operating system , supports multi processes ( unlike arduino runs 1 process @ time). if compare price of rpi , arduino build in wifi find have same price approximately.
