Use the name of the command to choose whether you are finding or deleting a file. Name your program assn8 and create two soft links to it. Name the first link findit and the second delit. When you run your program, you can test the name by which you invoked it to determine which function to perform.

Once you have determined whether you are finding or deleting, test for the -i option on the command line. If options does not exist, search/delete all files matching name given. If -i option exists, you are to find or delete filenames by matching inode rather than name.

Assumptions:

Start search at current directory.
Filenames may include path info.

use pwd to get the current directory and assign it to your own cwd variable
If number of arguments on command line is none
assume (set variable to remember) you are are searching for file by filename


else
(use case for this conditional statement)
if 1st argument on command line is -i
remember (set variable) that you are searching for file by inode
discard 1st argument with shift

else if 1st argument on command line is -n

remember (set variable) that you are searching for file by filename
discard 1st argument with shift

else if 1st argument begins with a - (e.g -a, -e, -p, -bob, etc)

print error "bad option"
exit with return code of 1

end of case

endif

if number of arguments on cmd line is less than one

ask user for name of file to find
place it into command line argument list (see set page 300)

endif

while there are arguments in cmdline argument list

if this program run as findit
if search is by inode (check flag)
test for existence of file specified
if error ( invalid filename )
print error and exit with return code of 2
endif

get inode of file
use find to list all files of the same inode as the specified filename, use your $cwd as the starting point

else (search by filename)

Use sed to remove any path info from argument
use find to list all files of the same name, use your $cwd as the starting point
endif
