script similar to rm utility
1. The problem statement, all variables and given/known data:

saferm is a replacement for the rm utility. Rather than removing files, it move files in a sub directoy called".saferm" in the user's home directory. If "~/.saferm" doesn't exist, it is automatically created. The -l options lists the current contents of the "~/.saferm" directory.

Only the -l option or a valid existing filename can be specified at one time. Print a suitable error message and terminate the script otherwise.


2. Relevant commands, code, scripts, algorithms:
  1. check if one argument is given, if anything other than one argument was passed an error message should be printed.
  2. check if the "~/.saferm" directory exists using an "if" statement. If it doesn't, create it.
  3. In the third part, check if "-l" was passed using an"if" statement, If it was, then display the files in the "~/.saferm" directory. If not, then move the file to the "~/.saferm" directory.



3. The attempts at a solution (include all code and scripts):
Code:
if [ $# != 1 ]
   then
      echo "Usage: saferm  -l  (or a filename)" >&2
      exit 1
fi



if[! -d ~/.saferm]
   then
       mkdir ~/.saferm
fi

if["$1-l"]
then
    ls -l ~/.saferm
fi

invsync

invsync(8)						      System Manager's Manual							invsync(8)

NAME

       invsync - Synchronizes system inventory

SYNOPSIS

       /usr/bin/invsync

DESCRIPTION

       The  invsync  utility creates a Master Synchronization Inventory (MSI) file and a Customized File Inventory (CFI) file.	These files can be
       used to preserve the customized or modified state of your system in the event of a new installation.  The MSI file contains a complete list
       of  files  installed  by the setld utility and the state of those files when they were installed.  The CFI file contains the names of those
       files installed by the setld utility that have been customized or modified since the installation.  The files listed in the  CFI  file  are
       overwritten if you perform a new installation of the operating system.

       You must have superuser privileges to run the invsync utility.

       The  invsync  utility calls the usync utility to create the MSI file.  After the MSI file is created, the invsync utility calls the udetect
       utility to compare the state of the files shown in the MSI file with the current state of the files installed on the  system.   If  a  file
       state differs, an entry is written to the CFI file.

       Edit  the  CFI file to remove the entries for files that you do not want to back up. The CFI file and the MSI file are written in the setld
       inventory file format. For more information, refer to the stl_inv(4) refernce page.

RESTRICTIONS

       You must have superuser privileges to run the invsync utility.

FILES

       Subset lock files Subset inventory files Customized File Inventory Master Synchronization Inventory
