Linux shell project - extra credit

In this project you need to create a backup script. You are allowed to use only shell commands or your own additional scripts written in bash. You cannot use perl scripts or your worn C/C++ programs.

The script schould create a zip archive of the directory specified as a named argument source and save this zip archive inside the directory specified as named argument saveto (or if the argument is not given in the default directory hardcoded within the script file). If an additional argument copyto is given, the script should take this argument as the name of the share folder, mount this folder, and ocpy the archive file to the fodler as well. The login name and passwords can be either passed to the script by using the named arguments login and pass, or if omitted the script should prompt the user for them (note: use timed out prompt to limit the waiting time).

The script should save the archive file under the name specified by the argument name with the date prefix. For example, if the user runs the command:

$> ./backup --source:/home/dementiev/ist334 --saveto:/backup/data --name:proglang

In addition to creating the archives the script should make sure than you do not store more than 10 old archives in the specified directory. If you do, the script should remove the oldest copies.

The commands to use (recommended):

• read - reads user input from the keyboard
• date - prints current date/time information
• grep - does simple and regular expression search
• head - prints only the first n lines of the input file
• tail - prints only the last n lines of the input file
• sort - sorts the given input
• ls - prints the content of the specified directory
• wc - counts the number of lines/words/characters in the input
• tr - does the simple substitution
• cut - prints the specified fields/bytes of the input
• mount - mounts a device/network share to the specified folder. For example:

  $ mount -t smbfs -o username=daniel,password=mypass //ist-cit/daniel myprogs

  where //ist-cit/daniel is the name of the network drive you would like to map, and myprogs is the name of the directory (in the current directory), to which you want to map the network drive
• cp - copies a given file to teh specified destination
