Shell script won't reading non- .sh files [duplicate]

This question already has an answer here:

Read a line-oriented file which may not end with a newline

6 answers

#!/bin/bash

while read p
do
 echo "$p"
done < numbers.txt

This script is only reading and allowing me to print .sh files. I have tried it with .txt files (like above but it does not print anything.)

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Please add a sample of the contents of numbers.txt. The filename suffix means nothing on Unix systems. Both .sh and .txt files are just text files.

Your file does not contain a single terminated line. read can only read complete lines.

I guess it would be more correct to say that read reads the line (and assigns it to variable p) but returns false, having encountered EOF while doing so: hence the body of the while loop is not executed.

That's because you are printing test not variable p
Try this:

#!/bin/bash

while read p
do
 echo "$p"
done < numbers.txt

Test:

$ cat numbers.txt
1
2
345
678
9
$ bash script.sh
1
2
345
678
9
$

my apologies. I forgot to edit that ou, I was just testing something there. But even when changing to echo "$p", nothing prints

@CesaSalaam It works for me, are you sure that numbers.txt file is not empty?
