I have a script (A) which begins with a #!/bin/sh shebang.

There is another file (B) which doesn't begin with #!/bin/sh; it has some environment variables which I need to set for A to work.

The file B runs fine, and sets the variables when executed from .bash_profile. For example, in my .bash_profile file:

{. /(full_path)/(envname)/(filename).sh;}

When I write same line in my A script file, nothing happens. Why not?

I did echo $env_variable_name; this gives me the correct path when executed via .bash_profile but gives me blank when via my script A. I tried

  • /(full_path)/(envname)/(filename).sh

  • SCRIPT_FULL_NAME=$(readlink -f "$0")
SCRIPT_PATH=$(dirname $SCRIPT_FULL_NAME)
sh ${SCRIPT_PATH}/(filename).sh

What should I do?

  • What's in your `B` file? Make sure it has no bashisms (e.g. `export foo=bar` rather than `foo=bar; export foo`) - or change `A`'s interpreter to `/bin/bash`. You should be able to trace execution using `sh -x A`; that's often helpful in debugging shell scripts. – Toby Speight May 31 '16 at 09:44

There is another file (B) which doesn't begin with #!/bin/sh; it has some environment variables which I need to set for A to work.

In this case you should source you script B in script A. To source a script in sh, the command is:

. /path/to/B.sh

Note that the . is not the beginning of a relative path to script B.
