How to reference a file relative to the current dir in a shell script?

  • 772

I want to run a shell script that copies a file. I don't like to make absolute reference to that file.

myproject/target/myapp.jar
myproject/docs/copy.sh

copy.sh contains: scp ~/Projects/myproject/target/myapp.jar user@myip:/var/www

Question: how can I run the copy.sh shell script and reference the myapp.jar relative? Like first walking up one folder, and then going into /target?

command-line

    From myproject/docs/copy.sh you want 2 directories up and into target. You can do that with ...

    ../../target/myapp.jar

    This though ...

    scp ~/Projects/myproject/target/myapp.jar user@myip:/var/www

    I would use a variable and set it at the beginning of your script or from a configuration. You can't use ../../ inside the scp when you have "Projects" above it.

    This will give you the directory your script is in:

    DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"
