#
# Looking for a file with a certain pattern? But you can't
# remember where the file is, but know its somewhere in or 
# below the current directory.  This is for you.
#
# You do not give filenames as the setup is to look at all
# files in the cwd, or look in cwd and all subdirectories.
# 
# If you want only to look at files in the current directory
# and not any subdirectories DON'T use the -R option.
# DEFAULT is to do only files in the current directory.
#
# Should be able to use all grep capabilities.
#
# SYNTAX:
#   grepr [-R] [arguments_for_grep] pattern
#
#   The -R tells it to go recursively, else it will 
#   look only at files in the current directory.
#
# EXAMPLES:
#   grepr -R -b pattern
#   grepr -R pattern
#   grepr -v pattern
#   grepr -vb pattern
#
# OTHER POSSIBILITIES:
#   EXAMPLES from the command line:
#
#	### Won't do binary and other data type files, just text.
# 	alias grepr 'grep \!* `find . -type f -print`'
#
#	### To do binary and other data type files
#	### but does have problems with control characters
#	### Maybe pipe to 'tr -d '\xx''.  (Limited help.)
# 	alias egrepr 'egrep \!* `find . -type f -print`'
#
# LIMITATION:
#    Does not look at ALL non-text files (ONLY looks at 
#    FrameMaker, PDF, Microsoft, and compiled C code data 
#    formats (binary), graphics, and compressed files).
#
#    Does not look at 'dot' files (.login for example) as
#    only an 'ls' is done.
#
# BUGS:
#    It does runs VERY slowly - intensive for the filesystem.
