Ubuntu: JRuby startup warning

[SgtBalogh]

Environment

• JRuby version (jruby -v) and command line (flags, JRUBY_OPTS, etc)
  jruby 9.2.0.0 (2.5.0) 2018-05-24 81156a8 OpenJDK 64-Bit Server VM 25.191-b12 on 1.8.0_191-8u191-b12-0ubuntu0.16.04.1-b12 +jit [linux-x86_64]

• Operating system and platform (e.g. uname -a)
  Linux osboxes 4.15.0-42-generic Log wrapper #45~16.04.1-Ubuntu SMP Mon Nov 19 13:02:27 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Other relevant info you may wish to add:

• Installed or activated gems
  Rails gems

• Application/framework version (e.g. Rails, Sinatra)
  Rails 5.2.2

• Environment variables

Expected Behavior

JRuby 9.2.6 works fine in Linux, thanks for this great software. However we get the attached error during startup. What are we doing wrong?

• Describe your expectation of how JRuby should behave, perhaps by showing how CRuby/MRI behaves.
  Just not print that error :)

• Provide an executable Ruby script or a link to an example repository.

Actual Behavior

/home/osboxes/Applications/jruby-9.2.6.0/bin/jruby.sh /home/osboxes/Documents/workspaceRuby/kubarails/bin/rails server -b 0.0.0.0 -p 3000 -e development
/home/osboxes/Applications/jruby-9.2.6.0/bin/jruby.sh: 118: [: /home/osboxes/Applications/jruby-9.2.6.0/lib/jruby.jar: unexpected operator
/home/osboxes/Applications/jruby-9.2.6.0/bin/jruby.sh: 121: [: /home/osboxes/Applications/jruby-9.2.6.0/lib/jruby.jar: unexpected operator

/home/osboxes/Applications/jruby-9.2.6.0/bin/jruby.sh: 283: /home/osboxes/Applications/jruby-9.2.6.0/bin/jruby.sh: : Permission denied

Thanks in advance.

All the best,

@SgtBalogh as a test can you try to change top line of jruby.sh to:

#!/bin/bash

I am guessing this script has some bash syntax and your /bin/sh is being stricter...

@enebo: Thank you for your prompt response.
It just works (a little bit), but there are still these errors:

/home/osboxes/Applications/jruby-9.2.6.0/bin/jruby.sh /home/osboxes/Documents/workspaceRuby/kubarails/bin/rails console -- --prompt simple
/home/osboxes/Applications/jruby-9.2.6.0/bin/jruby.sh: line 283: [: missing `]'
/home/osboxes/Applications/jruby-9.2.6.0/bin/jruby.sh: line 283: : command not found
Loading development environment (Rails 5.2.2)

This is line 283 im my jruby.sh:
if [ "$NO_BOOTCLASSPATH" != "" || "$VERIFY_JRUBY" != "" ]; then
if [ "$PROFILE_ARGS" != "" ]; then
echo "Running with instrumented profiler"
fi

Thanks again

Interesting...I can repro this as well. bin/jruby itself is our main shell script but seemingly bin/jruby.sh introduced some bashism and seemingly an error even in sh. We will fix this. For now I recommend bin/jruby itself.

./bin/jruby.sh -e 1
./bin/jruby.sh: line 283: [: missing `]'
./bin/jruby.sh: line 283: : command not found

@SgtBalogh I am having a hard time getting to see the initial problems with the script but I think it is because:

ls -l /bin/sh
0 lrwxrwxrwx. 1 root root 4 Jan 17 02:27 /bin/sh -> bash*

After 7c7362a the scripts runs for me...
