Simple Shell in C - Linux

You are required to implement a myssh (my simple shell) in Linux/Unix using C. I need this done in 2, 3 days max!!!

The myssh shell should allow a user to create new processes and view the progress of current processes.

In it's simplest form it should allow the user to execute an already available process.

For examle:

server#> ./myssh

myssh-shell:> ls -la

The myssh shell should also have acess to any underlying system variable

The myssh shell should support the following characteristics.

1. I/O redirection

Example: myssh-shell:> sort < file1 > file2

2. Concatenations (Appending a file into another file)

Example: myssh-shell:> cat file1 >> file2

3. Pipelining

Example: myssh-shell:> cat file1 file2 file3 | sort > file4

4. Executing commands in the background

Example: myssh-shell:> sort file1 & ; ls & ;

5. Accept simple signals

For example the Control+C should terminate the current process, not the rssh-shell

Also Control+Z should be ignored

6. Wild character support

Example: myssh-shell:>ls file*.t?t

7. Aliases handling

Example: myssh-shell:> createalias myhome "cd /home/users/myusername"

myssh-shell:> destroyalias myhome

8. Display Command History

The shell should display the XX last commands the user entered. The user should be allowed to execute one of those commands without typing it (for example by pressing the UP key)

FINALLY. THE CD command needs to be implemented (using chdir() in C)

Also the ls command needs to be implemented ! You will propably use *glob* or *fnmatch* for wildcards...

## Deliverables

I attach starting code to work on it..
