This question already has an answer here:

I've just got a new PC running Ubuntu 16.04 and have transferred my work from my laptop running Ubuntu 14.04.

I have an executable jar file called timed_hri.jar.

On my laptop I can go to the directory and type ./timed_hri.jar and it runs. However, on my desktop it doesn't, I need this to run as I have a Python script that relies on using the ./ command on the file.

This is the output when I try it on my PC:

./timed_hri.jar: line 1: $'PK\003\004': command not found
./timed_hri.jar: line 2: $'\bne\355H': command not found

  • Try running java -jar ./timed_hri.jar – Nick Weinberg Jul 13 '16 at 15:08
  • Yeah, it works with that. Is there something I can do to get the direct ./ command to work on its own back? – oodles2do Jul 13 '16 at 15:14

  • Thanks for your help! I hadn't seen that question in my searches. David's response worked, I can now do ./ :). How do I mark your answer as correct? – oodles2do Jul 13 '16 at 15:22
