$ iwlist wlan0 scan | grep 'ESSID:"..*"'
ESSID:"OpenWrt"
ESSID:"dlink"
ESSID:"tplink"
ESSID:"linksys"
ESSID:"tenda"
ESSID:"pi"
ESSID:"somessid"
ESSID:"router"
.meta character matches any character.*will match zero or more characters- Can also use
grep -E 'ESSID:".+"'which will match at least one character between the double quotes
