OT: stringhe



sto studiando un script per ipchaind e mi trovo questa linea che non
riesco a capire. mi date una mano?

# The high ports used mostly for connections we initiate and return
# traffic.
LOCAL_PORTS=`cat /proc/sys/net/ipv4/ip_local_port_range |cut -f1`:\
`cat /proc/sys/net/ipv4/ip_local_port_range |cut -f2`

ok, cat /proc... | cut -f1 prende il primo valore del file e cat
/proc/... | cut -f2 il secondo, ma cosa fanno gli apici inversi e il
:\???

grazie
leonardo
