interactive script help

[mroy1300]

I am writing a script to automate wep cracking for ligament reasons only so my question is this...

I have a command that looks like this...

"airodump-ng --bssid (bssid) --channel (CH) --ivs -w (filename1) mon0"

I would like the script to ask

"what is the bssid?"

"what is the channel?"

"what filename would you like to write to?"

also note that i will need to use this information other places in the script.
another example would look like this...

"packetforge-ng -0 -a (bssid) -h (host mac) -l 255.255.255.255 -k 255.255.255.255 -y (fragment-0327-131221.xor) -w (filename2)"

script would ask

"what is name of fragment file?"

"what filename would you like to write to?"

I have looked around for a few days now and cant find the information anywhere on google or these forums but i may be asking the wrong questions so anyone please help im sorry if this is a simple question

This might be more appropriate posted at a general Linux or Linux scripting forum, but OK, I'll play.

Try Googling for something like "bash script prompt user input"
