Unwanted Shell expansion when assigning the output of a shell command to a variable
- by Rob Goodwin
I am exporting a portion of a local prototypte svn repository to import into a different repo. We have a number of svn properties set throughout the repo so I figured I would write a script to list the file elements and their corresponding properties. How hard can that be right.
So I write started writing a bash script that would assign the output of the svn proplist -v to a variable so I could check if the specified file had any properties.
#!/bin/bash
svn proplist -v $1
o=$(svn proplist -v "$1")
echo $o
now this works fine and echos the output of the svn proplist command. But if the proplist command returns something like
svn:ignore : * build
it performs a shell expansion on the * and inserts the entire directory listing prior to the build property value. So if the directory had a.txt, b.txt and build files/dirs in it, the output would look like.
svn:ignore a.txt b.txt build
I figure I need to somehow escape the output or something to keep the expansion from happening, but have yet to find something that works. There are other ways to do this, but I hate when I cannot figure something out. and I have to admin, I think this one beat me ( well given the time I can spend on it )
