## SCRIPT: 01_anyfile4Dir_findFILES4TYPE_allLEVS_find-f-file-grep.sh
##
## PURPOSE: Finds ALL the files (non-directory) whose file-type matches
##          a user-specified mask --- ALL files under the current Nautilus
##          working directory, multiple levels, if any --- using
##          'find', 'file', and 'grep'.
##
## METHOD:  Uses 'zenity --entry' to prompt for a type string.
##
##          Puts the output of the 'find-file-grep' combo of commands
##          into a text file.
##
##          Shows the text file using a text-file viewer of the user's
##          choice.
##
##        This utility will look for all files matching a user-specified
##        'type' --- searching recursively under the 'current' directory,
##         that is, the directory in which the selected file lies.
##
##        The valid 'types' are strings that are returned when the 'file'
##        command is applied to a file. Example: 'ASCII HTML document text'
##        In this case, the user might simply specify 'HTML' or 'text' or
##        'ASCII' for the mask, depending on what he/she is looking for.
##
## HOW TO USE: Right-click on the name of any file (or directory) in
##             a Nautilus list, after navigating to a 'base' directory.
##             Then choose this Nautilus script (name above).

## Created: 2010apr03
## Changed: 2010apr12 Touched up the comment statements. Changed
##                    the output file to go into the current working
##                    directory if the user has write-permission.
## Changed: 2010aug29 Added TXTVIEWER var.
## Changed: 2011may02 Added $USER to a temp filename.
## Changed: 2011may11 Get 'nautilus-scripts' directory via an include script.
## Changed: 2012feb29 Changed the script name in the comment above.
## Changed: 2013oct26 Changed the script name from 'find-f' to 'find-NOTdir'
##                    to indicate this script will list 'special' files
##                    as well as 'regular' files. Correspondingly, change
##                    the '-type f' in the 'find' command to '! -type d'.

## FOR TESTING: (show statements as they execute)
#  set -x
