Comment (by asan):

 > It seems that setting `TMPDIR` to a `tmp` directory inside the Tor
 Browser directory at the beginning of `start-tor-browser` would solve the
 issue with `<<`
 Your solution looks working. However, if you want to set temporary
 directories for the script correctly, it would be logical to set them in a
 way which resolves
 [[https://trac.torproject.org/projects/tor/ticket/7449|#7449]] too.

 > There are also other things in this script, which are often considered
 to be a bad practice. In particular
 I would add also another point: `echo`
 [[https://unix.stackexchange.com/questions/65803/why-is-printf-better-
 than-echo|must]] be replaced by `printf` everywhere.
