A $ in my path...

A $ in my path...

[ProblematicRoutes]

Hello all,

I have just had my work system set upto use cygwin. Unfortunately, my home
directory and all other directories which are mapped to network stores and
properly backed up have a $ sign in their path:

$ pwd
//sbs01/students_home$/csmith

This $ sign causes problems everywhere - with latex, with svn, with anything
that uses ~ to refer to my home directory, because it expands to ...$/...
and bash tries to parse the $/ as a variable.

Does anyone know how to change this or hide this? It may only be a problem
with pwd and applications which use this because, e.g., when I'm in / (which
is C:\cygwin) and I type pwd I get "/" as the result.

Thanks heaps for your help!
Andrew

Would this work?
cd /home
ln -s $HOME/csmith
cd csmith
export HOME=`pwd`

Really?  I'm hard-pressed to think of ways that you could use ~ or
$HOME that would then lead to the result of that expansion being
re-analyzed for further parameter expansion as well.  It seems like
you'd have to go out of your way to make that be a problem.

But the workaround, if you have the privileges to do it, would be to
make a $-less symbolic link and change your passwd entry to match.

Dear Mark, Sid

I'm not sure why it is being expanded then, but if I use includes in latex
(for example, \input{../someinclude.tex}) or a script like the following
that causes the problem to occur with cygwin:

#!/bin/bash

echo Committing /cygwin directory in repo:
svn ci ~

I will try yours and Sid's solutions tomorrow (I think they're the same
idea? Correct me if I've misunderstood your suggestion!)  when I'm back in
the office, and hopefully they will fix the problem.

Andrew

If shortcuts don't work, here's two other ideas:

    * Cygwin mount -- mount a sane path to the problematic path
    * NTFS junction point (like a *ux soft link) -- junction a sane path
      to the problematic path

This worked nicely, and so I've added it to my .bashrc - thanks!

I recommend protecting it to avoid repeating the process and getting
broken links; this should work (and also leaves $HOME alone if any of
the steps fail):

case "$HOME" in
   *$*)  cd /home &&  ln -s "$HOME" ./csmith && cd ./csmith && HOME="${PWD}";;
esac
