[SOLVED] awk split shows nothing

vincix · 04-22-2020, 03:31 PM

Can anyone help me to understand why this works?

Code:

df -h | awk '/Mounted on/{ split($6,a," "); print a[1]}'
Mounted

But this outputs nothing?

Code:

df -h | awk '/Mounted on/{ split($6,a," "); print a[2]}'

I would have expected to show 'on'.
This, on the other hand, works, if applied on the whole line:

Code:

df -h | awk '/Mounted on/{ split($0,a," "); print a[7]}'
on

If you print $6 you will see just the single word, "Mounted". How would you expect splitting $6 to reveal anything else?

Yes, I guess that was the reason why I posted in the newbie section. Thanks
