read for shell
Just want to write this done so that I don’t have to man again in the future:
CC=; while [ 1 ] ; do read -s -t 1 -n 1 CC; if [ "$CC" = 'q' ] ; then break; fi; clear; ls -als crtv_* | tail -15 ; done
-s is “don’t echo”, -t 1 is “timeout after 1 second”, -n 1 is “read one character only” (so don’t have to wait for enter.
Pretty usefule, actually this can be used to do some interact applications with shell.
