Help with creating a simple shell script

Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

1. The problem statement, all variables and given/known data:

Write a shell script that accepts two arguments. The two arguments are the
name of 2 files.
• If the arguments are not 2, display “need 2 arguments” and quit.
• If one or both of the arguments are directory, display “No directories
please” and quit.
• If one of the two files does not exist, display “filename: no such file” where
filename is the name of the missing file, then quit. If the two files do not
exist, repeat the above for the 2 files, each in a separate line and quit.
• If the 2 files do exist, then display one of the two phrases, “The two files
are identical” or “The two files are not identical” then quit.




3. The attempts at a solution (include all code and scripts):

Code:
{
printf "%s\n" "$1"

} > tempfile.$$

BBACKUPQUERY(8) 						    Box Backup							   BBACKUPQUERY(8)

NAME
bbackupquery - Box Backup store query and file retrieval SYNOPSIS
bbackupquery [-q] [-c configfile] [command ...] DESCRIPTION
bbackupquery is the main way of interacting with the backup store from a Box Backup client machine. It supports both interactive and batch modes of operation. It can be used to reviewing the status of a client machine's backup store, getting status from the store server. The main use is to retrieve files and directories when needed. bbackupquery supports interactive and batch modes of operation. Interactive mode allows for interaction with the server much like an interactive FTP client. Batch mode is invoked by putting commands into the invocation of bbackupquery. Example: bbackupquery "list home-dirs" quit Note that commands that contain spaces are enclosed in double quotes. If the quit command is omitted, after the preceding commands are completed, bbackupquery will enter interactive mode. OPTIONS
-q Quiet. Suppresses status output while running. -c configfile Use configfile instead of the default bbackupd.conf file. Can be a relative or full path. COMMANDS
The commands that can be used in bbackupquery are listed below. help Displays the basic help message, which gives information about the commands available in bbackupquery. Use the form help command to get help on a specific command. quit End the session with the store server, and quit bbackupquery. cd [options] directory-name Change directory. Options: -d consider deleted directories for traversal -o consider old versions of directories for traversal. This option should never be useful in a correctly formed store. lcd local-directory-name Change directory on the client machine. To list the contents of the local directory, type sh ls (on Unix-like machines). list [options] [directory-name] The list (or its synonym ls) command lists the content of the current, or specified, directory. The options are as follows: -r recursively list all files -d list deleted files and directories -o list old versions of files and directories -I don't display object IDs -F don't display flags -t show file modification time (and attr mod time, if the object has attributes). -s show file size in blocks used on server. Note that this is only a very approximate indication of local file size. ls [options] [directory-name] Synonym for list. pwd Print current directory, always relative to the backup store root. sh shell-command Everything after the sh is passed to a shell and run. All output from the command is displayed in the client. Example: to list the contents of the current directory on the client machine type sh ls. compare -a compare -l location-name compare store-dir-name local-dir-name Compare the current data in the store with the data on the disc. Please note that all the data will be downloaded from the store, so this can be a very lengthy process depending on the size of the store, and the size of the part you are comparing. Options: -a compare all locations. -l compare one backup location as specified in the configuration file. This compares one of the top level store directories. -c set return code. The return code is set to the following values, if quit is the next command. So, if another command is run after the compare, the return code will not refer to the compare. This option is very useful for automating compares. Return code values: o 1 -- no differences were found o 2 -- differences were found o 3 -- an error occured get object-filename [local-filename] get -i object-id local-filename Gets a file from the store. Object is specified as the filename within the current directory. Local filename is optional. Ignores old and deleted files when searching the directory for the file to retrieve. To get an old or deleted file, use the -i option and select the object as a hex object ID (first column in listing). The local filename must be specified. getobject object-id local-filename Gets the object specified by the object id (in hex) and stores the raw contents in the local file specified. Note: This is only useful for debugging as it does not decode files from the stored format, which is encrypted and compressed. restore [-d] directory-name local-directory-name restore -r Restores a directory to the local disc. The local directory specified must not exist (unless a previous restore is being restarted). The root cannot be restored -- restore locations individually. Options: -d restore a deleted directory -r resume an interrupted restore If a restore operation is interrupted for any reason, it can be restarted using the -r switch. Restore progress information is saved in a file at regular intervals during the restore operation to allow restarts. usage [-m] Show space used on the server for this account. Display fields: o Used: Total amount of space used on the server o Old files: Space used by old files o Deleted files: Space used by deleted files o Directories: Space used by the directory structure When Used exceeds the soft limit, the server will start to remove old and deleted files until the usage drops below the soft limit. After a while, you should expect to see the usage stay at just below the soft limit. You only need more space if the space used by old and deleted files is near zero. The -m option displays output in machine-readable form. BUGS
If you find a bug in Box Backup and you want to let us know about it, join the mailing list[1] and send us a description of the problem there. To report a bug, give us at least the following information: o The version of Box Backup you are running o The platform you are running on (hardware and OS), for both client and server. o If possible attach your config files (bbstored.conf, bbackupd.conf) to the bug report. o Also attach any log file output that helps shed light on the problem you are seeing. o And last but certainly not least, a description of what you are seeing, in as much detail as possible.
