Beginners UNIX/Linux project

Write all scripts in bourne shell.

Use echo statements AND comments in your scripts.

2. Write a shell script that takes in any number of command line arguments, but quits

when a zero (0) is found.

Example:

[url removed, login to view] 1 2 3 0 4 5 6 t y u i i

[url removed, login to view] should echo out each command line argument, and quits when a zero is found.

Also, echo out that it is exiting because the zero was detected.

3. Write a script that must take in one command line argument, which will be the name

of a directory or file in the current working directory.

Tell me whether it is a file or directory that was put in on the command line.

If it is a file, tell me if the file length is zero or greater.

If it is a directory, tell me if the direcory is writable and readable by the

process.

If you cannot find the command line argument, tell me.

4. Write a script that asks the user for integer values, one at a time. Add up the

integers and print the current total, before prompting for the next integer. The

script will work until a Control-D is detected. Once Control-D is detected, print

the final total.

All of the above scripts should be well documented and the code should as simple (a beginner should be able to understand it) as possible.
