I'm trying to install Bazel on my EC2 Ubuntu machine. I download the .sh file with wget from the latest Bazel release and then I run it with sh ./bazel-0.2.1-installer-linux-x86_64.sh. I get the following error:
./bazel-0.2.1-installer-linux-x86_64.sh: 106: ./bazel-0.2.1-installer-linux-x86_64.sh: Syntax error: "(" unexpected
Looking at line 106 in the .sh file, I see the following line: function usage() {. Not sure why the ( in that line would be an issue.
I've tried using other installers (bazel-0.2.1-installer-darwin-x86_64.sh, bazel-0.2.1-jdk7-installer-darwin-x86_64.sh, bazel-0.2.1-jdk7-installer-linux-x86_64.sh) and all of them have the same issue on the same line.
The normal syntaxes for functions are:
function usage { … }
usage() { … }
aren't they, not the combo?
However, the Bash manual on shell functions indicates roughly:
function usage [()] { … }
The exact notation in the manual:
functionname[()]compound-command[redirections]
Maybe using bash instead of sh would work?
bash ./bazel-0.2.1-install-linux-x86_64.sh
And comments indicate that this does indeed work.
