Bash script not running

Question

I am trying to learn bash scripting and I'm using Ubuntu Linux. I have written a simple Bash file to count the number of files in current directory. I have written the following script in a file:

#! /bin/bash

ls -1 | wc -l

And saved the file with the name countFile.

But when I am trying to execute the script using ./countFile it is not executing. It shows the following error:

bash: ./countFile: Permission denied

The countFile is in my home directory so why I haven't the permission. Am I doing something wrong or missing some important thing? Moreover, the ls -1 | wc -l command gives me the correct output when I run it from the terminal.
So how can I run the countFile script?

You need permission to execute the file. chmod +x countFile — Biffen

@JID It depends on whether you want to set all permissions to something specific or just modify certain ones. — Biffen

Why down votes? Some explanation may help to improve my questions for next time. Is it off-topics?. — RohanK

While you are giving like this,

./countfile

You have to make that file as executable using chmod.

chmod +x countfile

Or else you can use the other interpreter like this.

sh countfile

Or chmod +x so as not to change any of the other permissions.

while executing the file we need a execute permission for that file, we can change the permission or we just run as

. countfile

hew . will represent the current working shell

Not a good way to ‘execute’ a script; it might soil your shell.
