understanding the purpose of <If env | grep -q $EXAMPLE>
I have seen this code in a few places and my understanding is they are using it to determine what app called the script.
I have a script that is called by two different applications and what it to do one thing when called by one and something else when called by the other. How do I determine what app is calling the script? If my example is correct how would I determine the $EXAMPLE and is every running application assigned a variable name?
I thought about just writing a separate script but the script is caching some info from one app and then echoing out to the other app when it asks for it so I think it should stay as one script.
Any help or pointing me in the correct direction would be great.
Thank you,
Jason

NAME
script - make record of a terminal session
SYNOPSIS

The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
record is saved in the file typescript. See WARNINGS.
The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
when the forked shell exits or when Control-d is typed.
OPTIONS
The following option is supported:
-a Appends the session record to filename, rather than overwriting it.
NOTES
script places everything that appears on the screen in filename, including prompts.
