Answer:
There are several potential reasons why environment variables might not be set correctly in a subshell when running a shell script. Here are a few potential solutions that Ciara could try to resolve this issue:
Check the syntax of the script: Ciara should make sure that the script is correctly formatted and that there are no syntax errors that might be causing problems.
Use the "source" command: Ciara can try running the script using the "source" command, which will execute the script in the current shell rather than in a subshell. This can help ensure that the environment variables set by the script are available in the current shell.
Export the environment variables: If Ciara wants to set environment variables that will be available in subshells, she can use the "export" command to make the variables available in subshells. For example, she can use "export MYVAR=value" to set the MYVAR environment variable.
Use absolute paths: If the script references files or directories using relative paths, these paths might not be correct when the script is run in a subshell with a different working directory. Ciara can try using absolute paths to ensure that the script can find the correct files and directories.
Check the permissions: Ciara should make sure that the script has the correct permissions and that she has permission to execute it.
I hope these suggestions help you. Let me know if you have any other questions.
