GNU Parallel facing silent exit and invalid option error

I tried performing the full installation from: http://git.savannah.gnu.org/cgit/parallel.git/tree/README

The installation was successful. It's working well when installed on Mac OS but on Amazon Linux (RHEL64) I am facing below issues:

1. 
   

   On running just parallel the command exits silently.

   
   
   

   dev-dsk % parallel
   
   dev-dsk %
   
   

   
   


2. 
   

   On running any command even parallel --version gives following error:

   
   
   

   dev-dsk % parallel --version                                               
   
   parallel: invalid option -- '-'
   
   parallel [OPTIONS] command -- arguments
   
       for each argument, run command with argument, in parallel
   
   parallel [OPTIONS] -- commands
   
       run specified commands in parallel
   
   

   
   
   

   Same error with running parallel --gnu.

   
   

IMO, there is no conflict with NO conflict with Tollef's parallel of moreutils package as moreutils doesn't exit on my machine.

Please help me understanding how to make GNU Parallel work on RHEL64?

  Note that the man page does not prove there's no conflict. I don't know what shell you use, but with bash you can run the command type -path parallel and it'll tell you what version of parallel you are running.

Not sure why it was not working as for me there was just one executable named parallel in my system path.

But I was able to fix it as below:

1. Run whereis parallel. This gives all the paths where executables named parallel is present. For my case there was just one path /usr/local/bin/parallel. Running using this path works just fine.


2. You can add an alias for this in ~/.bashrc or ~/.zshrc file like alias parallel='/usr/local/bin/parallel'
   

And now parallel works like charm.

dev-dsk % parallel --version
