How to import files in bash from a different folder-CodePudding

my project looks like this:

helper/
      helper_func.sh
main/
      my_program.sh

How do I import helper_func.sh in my_program.sh. If all files are in the same folder I just do source helper_func.sh and I can import the functions but if I do source ../helper/helper_func.sh it can't seem to find it.

What am I doing wrong?

CodePudding user response：

".." is relative to the present working directory, not relative to the script's source code. So it depends what directory you run the script from. Which makes it a bad idea because you generally can't know where someone will run a script from.

One possible trick to use is $0 which generally should contain the location of the script. So...

source `dirname $0`/../helper/helper_func.sh

might do what you want, but you'll have to experiment.
