Original GitHub issue: https://github.com/netblue30/firejail/issues/181

While one can use “special” characters in a directory or file name when using --whitelist or --blacklist[1] or the whitelist or blacklist options in a profile configuration file, I did not find how to use an exclamation mark[2] character in a directory name.

I added the following line in my iceweasel.profile
whitelist ~/!down
When running
firejail --debug iceweasel
I get
Error: "~/!down" is an invalid file name
I also tried escaping the ! character, quoting the path, quoting the whole line; does not work.

When trying on the command line with
firejail --debug "--whitelist=~/!down" iceweasel
I get
zsh: event not found: down
When trying on the command line with
firejail --debug "--whitelist=~/\!down" iceweasel
I get
Checking filename ~/!down Error: "~/!down" is an invalid filename

Using a space in the file name is working[3].
Using accents in the file name is working[4].

What am I missing?

[1]- man firejail is providing the sample firejail "--blacklist=/home/username/My Virtual Machines"
[2]- U+0021 EXCLAMATION MARK / '!'
[3]- Output of firejail --debug iceweasel: Removed whitelist path: whitelist ~/broap burp
[4]- Output of firejail --debug iceweasel: Removed whitelist path: whitelist ~/Ümlautißéèùça_marche

I'm trying to stay away from special chars in filenames. It is a SUID program, I have to protect it somehow.
