Maybe I'm asking the wrong question.
Here's a new question.
How can I test to see if the word "tuber" is in the /etc/passwd file, reliably, and take an action if it is, and take a different action if it's not, in a bash shell script?
You won't need to read the file, use "getent passwd":
getent passwd | grep tuber
If 'tuber' is the username, you can shorten this to:
getent passwd tuber
or even:
[ -n "$(getent passwd tuber)" ] && tuber exists || tuber does
not exist
kowari:~# getent passwd john kowari:~# getent passwd summer summer:x:1001:1001:John Summerfield:/home/users/summer:/bin/bash kowari:~# getent passwd John kowari:~#
OTOH
kowari:~# grep -qiw john /etc/passwd && echo Found John Found John
kowari:~# grep -qiw jon /etc/passwd && echo Found John
kowari:~#
For more, man grep
