=== How to fix Permission Denied Error: "unable to execute" ===
'''Error description:'''

<pre>
$ ./bash-script.sh
unable to execute ./bash-script.sh: No such file or directory
</pre>

'''Resolution:'''
Add execute permissions to the script using:
<pre>
$ chmod +x bash-script.sh
</pre>

=== How to fix Line Ending Compatibility Error ===
'''Problem:'''
<pre>
$ ./bash-script.sh
-bash: ./bash-script.sh: /bin/bash^M: bad interpreter: No such file or directory
</pre>

'''Resolution:'''
Convert Windows line endings (CRLF) to Unix format (LF):
<pre>
$ sed -i 's/\r$//' bash-script.sh
</pre>

This error typically occurs when a script is created on Windows and transferred to a Unix/Linux system. The sed command removes the Windows carriage return characters (\r) that cause the interpreter error.
