Filter :<port> from list of IPs

Hello

I got a huge list of IPs with attached port numbers

123.21.32.54:8060
123.21.22.22:9600
22.22.12.32:81
...

and I want to filter the :<port> away to ping the whole list with nmap.
Whats the most handy method?

awk -F : '{ print $1 }' <filename>

Remove the ports with:

sed -e 's/:[0-9]*$//' -i <filename>

Run nmap with '-iL <filename>'.

Re: Filter :<port> from list of IPs

cut -d ":" -f 1

also works.
