# Author: Bob Orlando (Bob@OrlandoKuntao.com) #
# #
# Date: December 14, 1996 #
# #
# Program ID: chmod_exit_err_nomail.sh #
# #
# Usage: CHMOD_EXIT_ERR_NOMAIL -l -p priority -t tag -v \ #
# permissions fileid ... #
# #
# -l = Notify via logger command #
# (default is false) #
# -p = Logger priority string #
# (default is "user.err") #
# -t = Logger tag string #
# (default is "$LOGNAME[$$]") #
# -v = Verbose #
# #
# Option notes: Option (-l) MUST precede other options. #
# 'UNIX command options' MUST follow #
# function options. If command option #
# is -l, -p, or -t, and you've specified #
# function option -l, then you must also #
# supply both function options, -p and -t. #
# #
# Purpose: Change permission of one or more files, reporting #
# errors via stderr and logger, and exiting on error. #
# #
# Description: This function adds no new functionality to the UNIX #
# chmod command beyond automatic notification/logging #
# before exiting on error. Unlike CHMOD_EXIT_ERR, #
# notification here is via echo to stderr (not via #
# EMAIL_MSG library function). Optionally (-l), the #
# user may have the error logged in syslogs #
# (/var/adm/messages) via logger command. Logger -p #
# and -t options and option arguments also may be #
# be passed (both have defaults if omitted). #
# #
# Globals: No global variables assigned from this function. #
# "CMN_" prefix identifies local function variables. #
# #
# Calls: EXIT library function. (DOES NOT use EMAIL_MSG #
# library function for error reporting/notification.) #
# Optionally, WRITE_ERR_TO_SYSLOGS is also called. #
# #
# Exit_status: Exits with failure (1) on error. This is because #
# any error while changing file permissions is #
# potentially a show stopper. Else, returns 0. #
# #
# Notes: ..................................................... #
# ..................................................... #
# #
# Modified: 2004-04-02 Bob Orlando #
# v1.19 * Expand $AWK testing and assignment. #
# #
# 2004-03-03 Bob Orlando #
# v1.18 * Change set|egrep|awk to just set|egrep. #
