Linux Non-root script used search and list specific key words
Hy there all. Im new here. Olso new to terminal & bash, but it seams that for me it's much easyer to undarsatnd scripts than an actual programming language as c or anyother languare for that matter.

S-o here is one og my home works s-o to speak.

Write a shell script which:
-only works as a non-root user
-gets a directory or tar archive (*.tar.gz, *.tgz) as the main parameter
-traverses all of it and its subdirectories/archives to find all files containing “much Open, such Stack” in them and print their file names (-n parameter must be given for this)
-if tar archives are found, search for files in them as well without leaving any evidence that you unarchived anything
-print the number of found files (-c parameter must be given)
-check all arguments, both -c and -n may or may not have been given

NOTES:
-check all your parameters at the beginning of the script, and save the “presence” of -n and -c in some variables for later use.
The parameters may come in ANY order so do be aware of that.
you can use `$0 param1 param2 …` to make your script “recursive”.


my curent script looks like this:

Code:
!/bin/bash          

echo "Hello, "$USER". This script will search all files containing: much Open, such Stack"
   abc=$1
echo -n "Enter the search path and pres [ENTER]:"
echo

if [ -d $abc ];then
  #find . -type f -print $abc | xargs grep 'much Open, such Stack'
  ls -R $abc | xargs cat | grep 'much Open, such Stack'
else
  if [ "$abc" == *".tar.gz" ]; then
      tar -xvzf $abc
  fi
fi



olso i had one more script done wich did made more sens to me at the time, still dose:

Code:
#!/bin/bash

echo "Hello, "$USER". This script will search all files containing: much Open, such Stack"
$target
echo -n "Enter the search path and pres [ENTER]:"
read target
echo

if [ -d $target ];then
         find . -type f -print $target| xargs grep "much Open, such Stack"
        #ls -F $target| grep -v '/' #| xargs cat | grep "much Open, such Stack"
else
         if [ "$target" == "*.tar.gz" ]; then 
         tar -tzf $target
      fi
fi

as you can se the codes uses one of the to functions "ls" or "find" ( one being disabled )

My question is this:

why dont i get any kind of output on the second code no mater what path i give it, beeing tar, directory or a txt file, and gain no matter what function i use be it find or ls.


and why dose the first code works? sort of...

Any ideas?

virt-tar-out

virt-tar-out(1) 					      Virtualization Support						   virt-tar-out(1)

NAME

       virt-tar-out - Pack a virtual machine disk image directory into a tarball.

SYNOPSIS

	virt-tar-out -a disk.img /dir files.tar

	virt-tar-out -d domain /dir files.tar

	virt-tar-out -d domain /dir - | gzip --best > files.tar.gz

DESCRIPTION

       "virt-tar-out" packs a virtual machine disk image directory into a tarball.

       The first parameter is the absolute path of the virtual machine directory.  The second parameter is the tar file to write.  Use "-" to
       write to standard output.

EXAMPLES

       Download the home directories from a guest:

	virt-tar-out -d MyGuest /home - | gzip --best > homes.tar.gz

JUST A SHELL SCRIPT WRAPPER AROUND GUESTFISH

       This command is just a simple shell script wrapper around the guestfish(1) "tar-out" command.  For anything more complex than a trivial
       copy, you are probably better off using guestfish directly.

OPTIONS

       Since the shell script just passes options straight to guestfish, read guestfish(1) to see the full list of options.

SEE ALSO

       guestfish(1), virt-cat(1), virt-copy-in(1), virt-copy-out(1), virt-edit(1), virt-tar-in(1), http://libguestfs.org/.
