dos2unix Command Not Found: Troubleshooting and Installation

If the 'dos2unix' command is not found on your system, it means that the command is not installed or not accessible in your current environment.

To resolve this issue, you can try the following steps:

Check for Installation:

Run the following command to see if the dos2unix package is installed:
```
which dos2unix
```
If the output is empty or an error message appears, the package is not installed.
Install the Package:

Use the appropriate package manager for your operating system to install dos2unix:
- Ubuntu/Debian:

```
- CentOS/Red Hat:
```
sudo yum install dos2unix

For other operating systems, consult their documentation or package manager.
Verify Installation:

After installation, try using the dos2unix command again. If it still doesn't work, verify the installation process or check if the installation path is included in your system's PATH environment variable.

If you are still encountering issues, provide details about your operating system and any error messages you receive for further assistance.
