How to get file size

[Tison]

How do I get the freespace for a file system ?

I want to put a check in a script that will report and perform calculations on the freespace amount.
Manually I type "df -k" but this does not work in my script because the columns are not always equal lengths (if you know what I mean).

df -k | tr -s ' ' ' ' | cut -f3 -d ' ' grep -v Free

will return the free space column only. You could then put this in a file and cat it to do whatever arithmetic you need. HTH.
