[SOLVED] Show disk usage of a command?

[correnos]

The command time shows the time taken by a command to complete. Is there a command that shows the change in disk usage caused by a command? I would like to know how large a package is when I install it from source.
Any other solutions to this would also be welcome.

You could use df on either side of the command:

kieren@George-Michael:~$ df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sdb6             59598820   4434544  52136832   8% /

kieren@George-Michael:~$ echo "hello world" > /tmp/diskspaceusage

kieren@George-Michael:~$ df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sdb6             59598820   4434548  52136828   8% /

Yeah, this thought did occur to me. I just wanted to know if there was a more streamlined way. I guess I could write a script for it...

Thanks.
