Re: stupid spaces in environment vars

Okay, the problem is in quoting in shell scripts, I think.

Here's an example:
#!/usr/bin/bash
curdir=`pwd`
echo $curdir
prodir=`cygpath $USERPROFILE`
Should be:

prodir=$(cygpath "$USERPROFILE")

echo $prodir
cd $prodir
Should be:

cd "$prodir"

cd /cygdrive/c/Documents\\\ and\\\ Settings/$USERNAME
Should be:

cd "/cygdrive/c/Documents and Settings/$USERNAME"

pwd
cd $curdir
Should be:

cd "$curdir"

See the pattern?  In general whenever you have a variable that might
contain spaces you just need to quote it.  Forget the triple-backslash
nonsense.  Double quotes are all you need.

thanks you very much. However, there is still something that doesn't work. Here's a simple script that has problems.

#!/bin/sh
# the user has write access to
src=`cygpath $USERPROFILE`
echo $src
r='snapshot1.pp.asu.edu'
opts=" -av --dry-run -e ssh"
rsync $opts "$src/" $USER@$r:~/$HOSTNAME





Please, why don't you RTFABSG: http://tldp.org/LDP/abs/html/
