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:

```nohighlight
df -Ph /web

```

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

What output do you get from the commands:

```nohighlight
/usr/xpg4/bin/df -Ph /web

```

and:

```nohighlight
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

```nohighlight
PATH=`getconf PATH`
df -kP /web | awk 'NR>1 {print $5}'

```

Print the 5th field without the % sign

```nohighlight
df -kP /web | awk 'NR>1 {print $5+0}'

```
