Part 3 Scripts

1. Use pico to edit the .login file and add aliases for your favourite (?) MS-DOS or VMS commands (eg. dir ls -l | more, del rm -i).
2. Create a new directory called~/mybin. Edit the .cshrc file and reset your path shell variable to include this directory (remember to include $path to ensure you don't lose all the existing search paths!).
3. Create a shell script that counts files you own in the current directory. Place this shell script in your mybin directory, change it's file permission to be executable and use the command,

   >source .cshrc

   to ask the shell to find this new command before attempting to run it.
4. Create a shell script that reads in 4 parameters (say filenames) from the command line and prints out a list of all the parameters, the number of parameters and then echo The third filename is and the value of the third parameter. Modify this to print out No parameters found if there are no parameters found. There is no particular easy way to count the number of arguments given; one way is to use a for loop along with a expr expression to count the number elements in the string (of parameters) $*.
5. Write a shell script called, say addcom, that moves a file to your ~/mybin directory and changes the file permission to be executable. Check this command works by creating a simple script that echoes It works! and then giving it as an argument to the new outcome command.
6. Write a shell script to produce a calendar for this month, whenever it is used. Build in options for the whole year, or even for a specified month and year.
7. Create a .logout file. Add commands to remove all *.o files from a program directory and display your filestore quota.
