Public bug reported:
I have Bash functions defined with punctuation-only names, such as - and
.., which now give errors when starting nested shells.
After a recent Shellshock patch, env shows these functions as having
names like BASH_FUNC_-(), and starting a second Bash in some way, such
as running a shell script, yields error messages like:
bash: error importing function definition for `BASH_FUNC_-'
With a double-nested Bash, each error message is displayed twice.
So far as I can tell the error message is spurious: the action function
- is being imported correctly. But it's irritating to have the terminal
clogged up with these messages, especially when just running utilities
which I didn't even know were written in Bash.
This is with bash 4.3-7ubuntu1.4.
