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?

gitaction

gitaction(1)						      General Commands Manual						      gitaction(1)

NAME

       gitaction - GNU Interactive Tools - per file type action script

SYNTAX

       gitaction directory file
       .gitaction directory file

DESCRIPTION

       gitaction  is a script that executes a different action for each file type specified. It is called by the gitfm program when pressing F2 or
       ^Xa (see the gnuitrc.TERM configuration files in the gnuit manual). The first parameter is the current directory name and the second one is
       the file name to be matched against the default patterns. The matching is done using the shell 'case' statement.  If you press F2 or ^Xa on
       a *.html file, gitfm will invoke a browser to view it, if you press F2 or ^Xa on a *.tar.gz file, gitfm will list the tar archive contents,
       if you press the same keys on a *.gz file, gitfm will display its uncompressed contents on the screen, etc ...

       If  you	press  F2  or ^Xa on a *.gif file or *.jpg file and you have the zgv utility installed, you will be able to see it. If you want to
       change the gif/jpeg viewer, all you need to do is to change its name in the gitaction script.

       There are many more file types and viewers that gitaction knows about.  In addition, if you are running under GNOME,  gnome-open  is  used,
       and on MacOS, open(1) is used. see(1) and metamail(1) are also used as fallbacks.

       If  all else fails, the file is displayed using $GNUIT_PAGER. Feel free to change this. If you want to find out what the default action for
       each file type is (or if you want to modify it), just read/modify the gitaction script.

       The script can be easily enhanced. Just read it.

       The .gitaction script is a local version of the gitaction script. When started, gitaction tries to search a script called .gitaction in the
       current	directory and, if it finds it, it starts it. If .gitaction's exit code is 0 ( .gitaction couldn't find a matching pattern), gitac-
       tion starts its own case statement trying to match the current file name (the second parameter) against its default patterns.

       The .gitaction script *must* be executable. An example of .gitaction can be found in the  directory  gitfm  is  installed  into.   (usually
       /usr/local/bin  or /usr/bin) Debian users can find it in /usr/share/doc/gnuit/examples/.  You should copy the example to the current direc-
       tory or your home directory and then modify it.
