Bash syntax error: unexpected end of file

Another thing to check (just occured to me):

• terminate bodies of single-line functions with semicolon

I.e. this innocent-looking snippet will cause the same error:

die () { test -n "$@" && echo "$@"; exit 1 }

To make the dumb parser happy:

die () { test -n "$@" && echo "$@"; exit 1; }

I think file.sh is with CRLF line terminators.

run

dos2unix file.sh

then the problem will be fixed.

You can install dos2unix in ubuntu with this:

sudo apt-get install dos2unix
