New submission from Ben Gertzfield <[email protected]>:
The undocumented (but unit tested!) pipes.quote does not correctly
escape '!', which cannot be passed to the shell outside of single-
quotes:
sh-3.2$ python
Python 2.6.1 (r261:67515, Jul 7 2009, 23:51:51)
[GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import pipes
>>> pipes.quote("omgshoes!")
'omgshoes!'
sh-3.2$ echo "omgshoes!"
sh: !": event not found
bash-3.2$ echo "omgshoes!"
bash: !": event not found
zsh-4.3.9% echo "omgshoes!"
dquote>
This needs to be single-quoted for safety:
sh-3.2$ echo 'omgshoes!'
omgshoes!
bash-3.2$ echo 'omgshoes!'
omgshoes!
zsh-4.3.9% echo 'omgshoes!'
omgshoes!
