1Scripts don't run in subshells, so this output looks correct to me. What are you expecting?Michael Homer– Michael Homer2019-04-23 21:27:00 +00:00Commented Apr 23, 2019 at 21:27

@jim-chriss, Michael is right: executing a shell script runs that script is a separate process, not as a subshell of your interactive shell.glenn jackman– glenn jackman2019-04-23 21:31:08 +00:00Commented Apr 23, 2019 at 21:31

@Michael Homer shell scripts do run in subshells if invoked using their names in terminal, I quote the tldp book page 28, says "This is the most common way to execute a script. It is preferred to execute the script like this in a subshell."Jim-chriss Charles– Jim-chriss Charles2019-04-24 08:25:00 +00:00Commented Apr 24, 2019 at 8:25

I will acknowledge that the book does say that, and that it does so because the book is incompetently written.Michael Homer– Michael Homer2019-04-24 08:29:29 +00:00Commented Apr 24, 2019 at 8:29

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
