How to list available space excluding mount points in home directories?

Question

I ran df -lP which gave me the following output:

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1             7.6G  2.2G  5.1G  30% /
varrun                506M  108K  506M   1% /var/run
varlock               506M     0  506M   0% /var/lock
udev                  506M   44K  506M   1% /dev
devshm                506M   12K  506M   1% /dev/shm
lrm                   506M   40M  467M   8% /lib/modules/2.6.24-26-generic/volatile
gvfs-fuse-daemon      7.6G  2.2G  5.1G  30% /home/vmadmin/.gvfs

How can I remove the line where it says /home/"can be anything"?

I can't use df -lP | sed '$d' because the output would be

Filesystem         1024-blocks      Used Available Capacity Mounted on
/dev/sda1              7867856   3622668   3845524      49% /
tmpfs                   513448         0    513448       0% /lib/init/rw
udev                    507692       124    507568       1% /dev
tmpfs                   513448         4    513444       1% /dev/shm

Answer 1

Reading your question now, a simple solution would be:

df -lP | grep -v '/home/' Where /home is the one you do not want to see and the -v in grep will give you the inverse of what you are searching. Basically you would be telling grep to search for all line that DO NOT have the /home with them.

If you want to be able to exclude other folders then do the following:

df -h | grep -ve "/home" -ve "/lib"

This would exclude all /home folders and all /lib folders. You can continue to add excluded folder by adding -ve and in "" the folder you wish to exclude.

Answer 2

How about this?

df -lP | grep -v "%\s\/home\/"

It filters all lines matching %, followed by single-whitespace-character and followed by /home/ by using grep.

Note to other readers: as already in the question it's important to use -P in df to keep predictable single-lined output.
