Code:
df | sed -n 's/.*\([0-9]\)%.*/\1/p'
i've been trying that. it will get you the last digit, but not the one in tens place. i dont know why a
Code:
df | sed -n 's/.*\([0-9]+\)%.*/\1/p'
doesnt work.

of course, you can add another [0-9] but that will only return if you have a number with 2 digits.

slackie: that one will fail if you dont have /dev in your line (for instance, for swap)

you are welcome korbin!

ok, h/w ...
i wrote the thing only for that case.. 1 drive under /dev/xxx ..
for sure if we have other devices listed the "grep" part will fail...
Regards
