Originally created by @icasdri on GitHub (Aug 12, 2017).
Original GitHub issue: https://github.com/netblue30/firejail/issues/1464

With a (completely) non-blacklisted /usr/bin:

  • a script with .sh extension (for instance /usr/bin/myscript.sh) with proper execute bit and shebang #!/bin/sh will fail to execute with Permission denied.
  • but the exact same script named without an .sh extension (for instance /usr/bin/myscript) will work just fine.

Unfortunately, there are some programs in /usr/bin like IntelliJ IDEA (/usr/bin/idea.sh) that have .sh extensions, and thus fail to start inside a firejail.
