Tools Bash take word after specific point and till next space?
Hello, I have an output like
Code:
Interface Chipset Driver wlan0 Intel 4965/5xxx iwlagn - [phy0]

and I want to take only the 'wlan0' string. This can be done by
Code:
a="Interface Chipset Driver wlan0 Intel 4965/5xxx iwlagn - [phy0]"
b=${a:25:6}
echo $b

The thing is that wlan0 can be something else, like eth0 or rausb0, this means that it can have more or less letters. So, what I want is to take the string from the letter No 28 till the next space. Is this possible?

Thanks Smilie

zsh-4.3.11[t]% echo "$b"
wlan0
