i want to disable log messages and run some scripts on startup which also take some input from user i do the following changes in cmdline.txt for remove boot messages
dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty3 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait logo.nologo loglevel=3
and to run script on startup i execute script in rc.local
now the boot messages is hide successfully but the problem is screen is also not displaying a output of script is there any way to display script output and hide boot messages at a same time ?
