[Solved] [Bash] Running java with space in the argument

Hi. I think this should be pretty easy, but I just can't. Hopefully somebody could help me.

Simply put: I want to run java command where the argument has a space in filename.

This is my script:

#!/bin/bash

TESTPATH="/home/laite/bin/test dir"
EXEC="java -jar \"$TESTPATH\"/some.js"

echo $EXEC
${EXEC}

and the output:

# laite@laite-arch ~/bin
> ./java_test.sh 
java -jar "/home/laite/bin/test dir"/some.js
Error: Unable to access jarfile "/home/laite/bin/test

Re: [Solved] [Bash] Running java with space in the argument

you should use TESTPATH="/home/laite/bin/test\ dir"

EDIT : i've found this http://stackoverflow.com/questions/1214 … -as-a-java

Re: [Solved] [Bash] Running java with space in the argument

Your first line says you're using bash, so... use bash features?

cmd=(java -jar "$jarpath"/some.jar)
printf '%q ' "${cmd[@]}"; echo
"${cmd[@]}"

Nice, this worked! Thanks.

Edit: And just now I understood why and how it worked. Snappy
