I use my .vimrc on a number of different machines, which all have significantly different versions of vim. Most versions boot up fine, but one of them has reports this (doctored) list of errors on startup:

Error detected while processing ~/.vimrc:
Undefined variable: pathogen
Invalid expression: pathogen#infect()
Invalid :syntax subcommand: enable
Unknown function: executable
Invalid expression: executable('xclip')
:else without :if: else
:endif without :if: endif
Invalid argument: indent on
Invalid argument: plugin on
Invalid argument: nrformats=alpha,hex,octal
Illegal arguments: fromstart
Not an editor command: colorscheme zobean
Unknown option: foldenable
Unknown option: foldcolumn=0
Unknown option: cursorline
Unknown option: winminwidth=0
Ambiguous mapping, conflicts with "^V<silent>"
Ambiguous mapping, conflicts with "^V<leader>"
Ambiguous mapping, conflicts with "j"

I know I can use if has('mouse') to test if mouse support is enabled. Is there a similar test I can do for the other commands, like pathogen, and settings and options that are commonly missing?

Note, I do not have permission to install programs on all of these machines, so installing the latest vim is not a valid option.

I intend to only maintain a single .vimrc for all machines, that will appropriately tailor the options to what is available.

Appendix: vimrc content

I will not include my entire .vimrc, as it about 250 lines long, but below is representative lines and sections causing each of the errors listed above:

execute pathogen#infect()
syntax enable
if has('win32')
    ...
elseif executable('xclip')
    ...
else
    ...
endif
filetype indent on
filetype plugin on
set nrformats=alpha,hex,octal
syn sync fromstart
colorscheme zobean
set foldenable foldnestmax=5 foldmethod=indent
set foldcolumn=0
set cursorline
set winminwidth=0
vnoremap < <gv
nnoremap <leader>~ vwb<esc>~
vnoremap jk <esc>

Most of the time when I'm using nemo, I don't want to worry about hidden files; but the times when I need to see hidden files are too numerous for me to toggle their visibility each time.

Is there an option to show all hidden files, but only after all other files? I'd want this to be a global setting, so not like the "Arrange Items" option.

When I use sudo twice in two piped commands, I get the following output:

$ sudo echo 'hello world' | sudo cat
[sudo] password for zoey: [sudo] password for zoey:

And must enter my password twice. The first time, it is hidden as usual, but the second is shown in plaintext.

$ sudo echo 'hello world' | sudo cat
[sudo] password for zoey: [sudo] password for zoey: 
password123456seven
hello world

After the command exits, anything I type to the command line is hidden, as if I were typing a password, although command outputs work (mostly) fine. This behaviour continues until I close the terminal.

I tried:

$ echo 'hello world' | sudo cat
$ sudo echo 'hello world' | cat

And both seem to have normal behaviour.

I don't want to have to use $ sudo bash -c "echo \'hello world\' | cat", which seems overly clunky, and would make quoted text a nightmare to handle.

Also, before anyone asks, yes, I know that echo and cat don't often require root permissions.
