Bash script

Hi friends you can solve my question about make 3 shell scripts?

Quote:

Write a shell script such that, given multiple files as arguments, showing, for each of them, his name and the number of lines it contains. Try it with any file.

2.

I have two copies of the same directory tree. They almost have the same files in both (one version may have a couple extra or missing files).

I need to Write a shell script that allows some system-administration tasks to be preformed automatically from a menu-driven interface. with automated following tasks:

Copy directory tree Delete files or directories Output Information (this part is done )

*Copy directory tree The “Copy directory tree” selection should prompt for two arguments: src & dest.

Write a Unix shell script named 'mode' that accepts two or more arguments, a file mode, a command and an optional list of parameters and performs the given command with the optional parameters on all files with that given mode. For example, mode 644 ls -l should perform the command ls -l on all files in the current directory that have mode 644.

I came up with this code.

I was wondering if anyone could help me with this problem:

Write a script called countFiles that takes two arguments, the initial directory and the number of levels and returns the count of all files (including directories) in the directories and subdirectories up to the number of levels.

Permissions are important for keeping your data safe and secure. Utilizing permission settings in Linux can benefit you and those you want to give access to your files and you don’t need to open up everything just to share one file or directory (something Windows sharing often does).

After making a bash file that creates directories and then transfers files from one directory to each created directories I am curious as to how I'd go about doing this in a batch file.

This question is kind of a phase II to the first question I posted at here

I have a directory that contains a bunch of sub-directories, .zip files, and other random files not contained within a sub-directory.

I'd like a command line script to remove all sub-directories from within the parent directory, but keep all zip files and loose files that don't belong to any sub-directories.
