unable to fetch environment varible in shell script

Question

I want to fetch some environment variable which are set in .bash_aliases file. I want use them in my bash script

#!/bin/dash
echo $PATH
echo $DEPOT_TOOLS

Both are coming empty string once call it in myscript. In the terminal these variable are printing successfully.

Could you add the lines that define the variables? Are they exported? http://stackoverflow.com/q/1158091/2424184 — eush77, Oct 13 '15 at 08:58
Why are you setting environment variables in a non-standard file intended to define aliases? — chepner, Oct 14 '15 at 17:48

All you have to do is source the .bash_aliases file -- however as dash does only supports POSIX shell syntax you'll likely find that there are definitions inside of .bash_aliases that don't work for dash. If this is the case simply put your aliases inside of a different file and source that. Also the environment variable PATH is generally always available not sure what's going on with your system.

#!/bin/dash
. .some_aliases
echo "$PATH"
echo "$something_else"
