I need a script to find out what devices are active

Hello,

I have worked many times to get info about active ports of my laptop, anyhow i never ever come up with such type of code but i can share with you the codes i have come up with in order to get information about active devices and ports. For example once i required to know the installed hardware’s on my system so i used bash$ ls dev command to get this info, it lists down all the hardware devices installed. And once i want to get information about the open ports so i used map command, it helps me to tell where the desired port is busy or idle and another code for currently active device is :

 # Code snippets from /etc/rc.d/init.d/network # … # Check that networking is up. [ ${NETWORKING} = "no" ] && exit 0 [ -x /sbin/ifconfig ] || exit 0 # … for i in $interfaces ; do if ifconfig $i 2>/dev/null | grep -q "UP" >/dev/null 2>&1 ; then action "Shutting down interface $i: " ./ifdown $i boot fi # The GNU-specific "-q" option to "grep" means "quiet", i.e., #+ producing no output. # Redirecting output to /dev/null is therefore not strictly necessary. # … echo "Currently active devices:" echo `/sbin/ifconfig | grep ^[a-z] | awk '{print $1}'` # ^^^^^ should be quoted to prevent globbing. # The following also work. # echo $(/sbin/ifconfig | awk '/^[a-z]/ { print $1 })' # echo $(/sbin/ifconfig | sed -e 's/ .*//')
