bash scripting -- popd with directories containing spaces

[unrequited]

So I'm messing around with my OLPC, finally learning linux because I've put it off so long, and I'm getting into the bash scripting to do things I'd rather not repeat over and over. Here's my question, how do I pass directory strings to push/popd that have spaces in them? Here's a basic script I want to flesh out later to run a command in each directory under a current tree:

#!/bin/bash

echo "starting craps, now in directory: `pwd`";

tree -idf --noreport |while read k;
* * do
* * * * echo "pushing $k to dirstack";
* * * * pushd $k 1>/dev/null;
* * * * echo "executing b.s. command in `pwd`";
* * * * popd 1>/dev/null;
* * done;

echo "done, now in directory: `pwd`";

This works FINE until you get to a directory with a space in the name...

I've tried piping the tree command to sed to try and escape the spaces:
|sed 's/ /\\\\ /g'

and even piping all that into sed again to encapsulate it all in single quotes:
|sed 's/.*/'\''&'\''\//g'

but I'm stumped.

From the prompt itself, you can certainly do a:
popd ./directory\ with\ spaces
and it will work just fine and if you want, you can scrap the space escaping and go straight to single quotes:
popd './directory with spaces'

but neither will work in a bash shell script passed to popd.

Can anybody help?

Try to quote the variable:

pushd "$k" 1>/dev/null

Or change the field seperator:

OLDIFS=$IFS

Do your stuff here....

IFS=$OLDIFS

Hi unrequited,
Welcome to the forums, glad you got your problem fixed. I was wondering about the OLPC itself, if you don't mind me asking a few questions. Did you get it through the b1g1 program? Why did you decide to acquire an OLPC? Is it a pretty good machine (as advertised)? Are you able to use the Mesh network?

Head onto keyboard is less likely to risk serious injury.

Head onto keyboard is less likely to risk serious injury.

But a damaged keyboard is a bigger loss than a damaged wall!

Priced keyboards recently?

Priced wallboard recently?

Just sayin'. :)

First Windows habit to break when using Linux: don't put spaces into file or directory names. Space are separators!

Space are separators!

Cheaper than wallboard, too.
