Question Checking Files with a Shell Script
Hey everyone,

I'm writing a shell script that needs to loop thru a directory and check a defined type of files(.df).

I use "checkfile.x" which is a compiled program to check those files. Sintaxis : checkfile.x DatefileName.df

The program displays something like this:
File: kanswer.df - start search
File: kanswer.df has 1 records
File: kaprvlmt.df - start search
File: kaprvlmt.df has 72 records
File: kapyhour.df - start search
File: kapyhour.df - Last record is NOT a ZZZ record
File: kapyhour.df has 90 records
File: kaseitem.df - start search
File: kaseitem.df has 173 records

Here comes the catch, what I would like to do is, get the files with "Error" (we know if a file has an error buy checking the status for example the legend "Last Record not a ZZZ record" or "Error") and display them so the user will know which files nee do to be fixed. So if we continue working with the example included I should get something like this:
File: kapyhour.df - start search
File: kapyhour.df - Last record is NOT a ZZZ record

And nothing else.


Ok here is what I got so far:
1-Access the files in the directory
2-Check them with the "checkfile.x" program
3-Save the result on $FILE_W_ERR
4-Validate if there's one of the legends("Error" or "ZZZ").
5-If true display the checkfile result else next record.

Code:
# Goes thru the data files
for FILE in *.df
do

    # Checks each of the files and stores the result
    FILE_W_ERR=`checkfile.x $FILE`

    #Looks for the Err message in the return value of checkfile
    INSTR=`echo "$FILE_W_ERR" | egrep -c "ZZZ"`

    # Validate if the checkfile found any errors
    if [ "$INSTR" -ne "0" ]
    then

        # Display file with possible Error
        echo $FILE_W_ERR
        echo #INSTR

    fi

done

This is returning this:
File: kanswer.df - start search
File: kanswer.df has 1 records
File: kaprvlmt.df - start search
File: kaprvlmt.df has 72 records
File: kapyhour.df - start search
File: kapyhour.df - Last record is NOT a ZZZ record
File: kapyhour.df has 90 records
File: kaseitem.df - start search
File: kaseitem.df has 173 records

The exact same result.

I ran out of ideas here, please let me know if you have something I can use to get this done.

Thanks in advance everyone !

osacompile

OSACOMPILE(1)						    BSD General Commands Manual 					     OSACOMPILE(1)

NAME

     osacompile -- compile AppleScripts and other OSA language scripts

SYNOPSIS

     osacompile [-l language] [-e command] [-o name] [-d] [-r type:id] [-t type] [-c creator] [-x] [-s] [-u] [-a arch] [file ...]

DESCRIPTION

     osacompile compiles the given files, or standard input if none are listed, into a single output script.  Files may be plain text or other
     compiled scripts.	The options are as follows:

     -l language
	   Override the language for any plain text files.  Normally, plain text files are compiled as AppleScript.

     -e command
	   Enter one line of a script.	Script commands given via -e are prepended to the normal source, if any.  Multiple -e options may be given
	   to build up a multi-line script.  Because most scripts use characters that are special to many shell programs (e.g., AppleScript uses
	   single and double quote marks, ``('', ``)'', and ``*''), the command will have to be correctly quoted and escaped to get it past the
	   shell intact.

     -o name
	   Place the output in the file name.  If -o is not specified, the resulting script is placed in the file ``a.scpt''.  The value of -o
	   partly determines the output file format; see below.

     -x    Save the resulting script as execute-only.

     The following options are only relevant when creating a new bundled applet or droplet:

     -s    Stay-open applet.

     -u    Use startup screen.

     -a arch
	   Create the applet or droplet for the specified target architecture arch.  The allowable values are ``ppc'', ``i386'', and ``x86_64''.
	   The default is to create a universal binary.

     The following options control the packaging of the output file.  You should only need them for compatibility with classic Mac OS or for cus-
     tom file formats.

     -d    Place the resulting script in the data fork of the output file.  This is the default.

     -r type:id
	   Place the resulting script in the resource fork of the output file, in the specified resource.

     -t type
	   Set the output file type to type, where type is a four-character code.  If this option is not specified, the creator code will not be
	   set.

     -c creator
	   Set the output file creator to creator, where creator is a four-character code.  If this option is not specified, the creator code will
	   not be set.

     If no options are specified, osacompile produces a Mac OS X format script file: data fork only, with no type or creator code.

     If the -o option is specified and the file does not already exist, osacompile uses the filename extension to determine what type of file to
     create.  If the filename ends with ``.app'', it creates a bundled applet or droplet.  If the filename ends with ``.scptd'', it creates a bun-
     dled compiled script.  Otherwise, it creates a flat file with the script data placed according to the values of the -d and -r options.

EXAMPLES

     To produce a script compatible with classic Mac OS:

	   osacompile -r scpt:128 -t osas -c ToyS example.applescript
