ssh hostnome `filename` doesn't work due to PATH

Fresh installation of Ubuntu and the remote machine won't
run scripts in ~/bin

ssh remotemachinename `echo $PATH`

showed ~/bin was not in the path for remote sessions but was when a log in was performed.

It appears that .bashrc is not executed in the same way with a remote command.
Adding, `echo 'in .bashrc'' to the top of the remote ~/.bashrc shows it IS
executed on remote command on the working machine.

Then: I noticed `ls` and 'ls' generate different results. `ls` appears to run remotely as hoped; 'ls' appears to do something on the remote machine and the local one.

Perhaps I should use speech marks. They behave ok. Anyway....

Since .bashrc is being executed ok remotely, I think there's something in it preventing the path being set as expected for remote commands. A check showed
the working machines had line 6 of the default .bashrc commented. This line
exits, doing nothing for a non-interactive shell.

So, should the path be set elsewhere for non-interactive shells? Is this a security measure or a logical one?

NFS mount ls shows user numbers not names

Machine 1 has user, `me'. `$ id me' shows 1004 as `me' was added as a user late in the life of the machine.

Machine 2 has user, `me'. `$ id me' shows 1000 as `me' was the first user added.

`$ sshfs 192.168.1.100:/home/me ~/remoteme' mounts the remote location ok but attempts to write to the remote drive fail with permission errors.

Attempting the same process with `$ sudo mount' generates the same result.

Setting NEED_IDMAPD=yes in /etc/default/nfs_common made no difference.

`$ls -lha' at the local machine to view the remote drive shows no user names, only numbers. The numbers indicate 1004 as the owner.

So, move the remote `me' user from UID 1004 to UID 1000 by logging into the remote machine as a user other than `me' and executing,

`$ usermod -u 1006 olduserat1000' to free up UID 1000

then

`$ usermod -u 1000 me'

pbzip2 I think. Detects number of cores automatically and uses them.
