Shows *real* filesystems (mounted) and usage (excluding duplicate ubifs0:rootfs and pymaemo overmounts):

Code:
df -h -x bind -x ubifs
Output looks like this:
Code:
N900:~$ df -h -x bind -x ubifs
Filesystem            Size  Used Avail Use% Mounted on
rootfs                228M  170M   54M  76% /
tmpfs                 1,0M   92K  932K   9% /tmp
tmpfs                 256K   88K  168K  35% /var/run
none                   10M   72K   10M   1% /dev
tmpfs                  64M  4,0K   64M   1% /dev/shm
/dev/mmcblk0p2        2,0G  1,7G  180M  91% /home
/dev/mmcblk0p1         28G  3,0G   25G  11% /home/user/MyDocs
Instead of:
Code:
N900:~$ df -h
Filesystem            Size  Used Avail Use% Mounted on
rootfs                228M  170M   54M  76% /
ubi0:rootfs           228M  170M   54M  76% /
tmpfs                 1,0M   92K  932K   9% /tmp
tmpfs                 256K   88K  168K  35% /var/run
none                   10M   72K   10M   1% /dev
tmpfs                  64M  4,0K   64M   1% /dev/shm

                      2,0G  1,7G  180M  91% /usr/share/pyshared
/opt/pymaemo/usr/lib/pyshared
                      2,0G  1,7G  180M  91% /usr/lib/pyshared

                      2,0G  1,7G  180M  91% /usr/share/python-support
/opt/pymaemo/usr/lib/python-support
                      2,0G  1,7G  180M  91% /usr/lib/python-support
/dev/mmcblk0p1         28G  3,0G   25G  11% /home/user/MyDocs
I know it isn't actually a "one-liner" (only one command), but still useful...

Backup to a remote server using tar/ssh:

Code:
tar cf - /local/path | ssh username@remote_server tar xfp - -C /remote/path
You need tar and ssh (client) installed.

The busybox df on the n900 does not have the -x option to df

Which df are you using and where did you get it? Are you using some PATH ordering to over ride busybox?

I'm using coreutils-gnu among other of the -gnu packages and have put /usr/bin/gnu first in my $PATH.

Install it (and/or any of the other -gnu packages) and run this:
Code:
echo "# Set PATH
PATH=/usr/bin/gnu:$PATH
export PATH" >> ~/.profile
You can do it as both user and root (to set it up in both environments).

Digital Sound Processing. Might be wrong abbreviation, but it's the sound 100%
