Need Generic command for disk space usage

Given this directory /web

I need to get the current usage (in %) on Linux and Unix both using the same command on bash shell ?

The command i tried was working on Unix (solaris) but does not filter the desired same value when run of Linux.

My command df -h /web | awk '{print $5}' | sed -n '2p'

Can you help me with a generic command for both unix and linux?

What output do you get from:
Code:
df -Ph /web

on your Linux system? What Linux distribution are you using?

What output do you get from the commands:
Code:
/usr/xpg4/bin/df -Ph /web

and:
Code:
df -h /web

on your Solaris system? What Solaris release are you using?

Please be aware that df prints results for file systems, NOT directories.
Is df aliased to sth. different on your linux system? On my system, your pipe in post#1 works as desired...

You are such an Amazing expert ...

df -Ph resolved the issue.

I will provide more data you requested in the near future.

df -Pk is most portable (e.g. works on Solaris 8) with a Posix PATH.
Print the 5th field
Code:
PATH=`getconf PATH`
df -kP /web | awk 'NR>1 {print $5}'

Print the 5th field without the % sign
Code:
df -kP /web | awk 'NR>1 {print $5+0}'
