To display all hidden dot files (i.e., files that start with a . character) in a directory using Bash, you can use the ls command with the -a and -l options.
The -a option tells the ls command to show all files, including hidden dot files, in the directory. The -l option tells the ls command to list the files in long format, which includes the file permissions, owner, group, size, and last modification time.
For example, to display all hidden dot files in the current directory in long format, you can use the following command:
$ ls -la
This will list all files, including hidden dot files, in the current directory in long format, and print the resulting list to standard output.
If you want to display all hidden dot files in a different directory, you can specify the path to the directory as an argument to the ls command, like this:
$ ls -la /path/to/directory
This will list all files, including hidden dot files, in the specified directory in long format, and print the resulting list to standard output.
Overall, using the ls command with the -a and -l options is a simple and effective way to display all hidden dot files in a directory using Bash. This can be useful for viewing and managing hidden files, and for exploring the contents of a directory.
