The script will extract the last digit of the input parameter. example, that is 4. This will be compared to the last digit of the current day of the month ( like day 14; that is 4). A message will displayed on the screen indicating if the digits are the same or not. (1 Reply)

getopt
GETOPT(1) BSD General Commands Manual GETOPT(1)NAME
getopt -- parse command options
SYNOPSIS
args=`getopt optstring $*`
set -- `getopt optstring $*`
DESCRIPTION
getopt is used to break up options in command lines for easy parsing by shell procedures, and to check for legal options. [Optstring] is a
string of recognized option letters (see getopt(3)); if a letter is followed by a colon, the option is expected to have an argument which may
or may not be separated from it by white space. The special option ``--'' is used to delimit the end of the options. getopt will place
``--'' in the arguments at the end of the options, or recognize it if used explicitly. The shell arguments ($1, $2, ...) are reset so that
each option is preceded by a ``-'' and in its own shell argument; each option argument is also in its own shell argument.
getopt should not be used in new scripts; use the shell builtin getopts instead.
EXAMPLES
The following code fragment shows how one might process the arguments for a command that can take the options [a] and [b], and the option
[c], which requires an argument.
args=`getopt abc: $*`
if [ $? -ne 0 ]; then
echo 'Usage: ...'
exit 2
fi
set -- $args
while [ $# -gt 0 ]; do
case "$1" in
-a|-b)
flag=$1
;;
-c)
carg=$2; shift
;;
--)
shift; break
;;
esac
shift
done
This code will accept any of the following as equivalent:
cmd -acarg file file
cmd -a -c arg file file
cmd -carg -a file file
cmd -a -carg -- file file
IEEE Std 1003.2 (``POSIX.2'') mandates that the sh(1) set command return the value of 0 for the exit status. Therefore, the exit status of
the getopt command is lost when getopt and the sh(1) set command are used on the same line. The example given is one way to detect errors
found by getopt.
DIAGNOSTICS
getopt prints an error message on the standard error output when it encounters an option letter not included in [optstring].
SEE ALSO sh(1), getopt(3)HISTORY
Written by Henry Spencer, working from a Bell Labs manual page. Behavior believed identical to the Bell version.
BUGS
Whatever getopt(3) has.
Arguments containing white space or embedded shell metacharacters generally will not survive intact; this looks easy to fix but isn't.
The error message for an invalid option is identified as coming from getopt rather than from the shell procedure containing the invocation of
getopt; this again is hard to fix.
The precise best way to use the set command to set the arguments without disrupting the value(s) of shell options varies from one shell ver-
sion to another.
