#
# Script: formgrep.shl
#
# Purpose: Show the lines in an Oracle forms (.fmb) file containing a
#    given string.  The first parameter is the name of the forms file, 
#    the second parameter is the string to search for, and the optional
#    third parameter is the number of lines to show before and after the
#    matched line.  Note that this third parameter, if greater than zero,
#    slows down the script substantially.  Specifying -1 for the third
#    parameter just shows the file name, if it contains matches.
#
# Usage: formgrep.shl $BANNER_LINKS/<formname>.fmb shrcomc 
#    or: formgrep.shl $BANNER_LINKS/<formname>.fmb shrcomc 2
#      (In this example, shrcomc is the string to search for, and 2 is the
#      number of surrounding lines to also show.)
#
#    To run this for all forms in a directory, you could use the "find"
#    command, such as in the following (which must be all on one line):
#
#    find $BANNER_LINKS -name '*.fmb' -exec formgrep.shl {} shrcomc \;
#       >formgrep.lst           -- use this to save results to a file

# History:
#    11/09/00: Original version.
#    08/22/01: Added optional third parameter to indicate the number of
#       lines to show before and after the matched line.
#    5/10/02: Split export command into two commands for other unix versions.
