command line arguments
--------------------------------------------------------------------------------
I have this while loop and at the end I am trying to get it to tell me the last argument I entered. And with it like this all I get is the sentence with no value for $1. Now I tried moving done after the sentence and it printed the value of $1 after every number. I don't want that I just want the last argument entered.
while [ $# -gt 0 ]
do
echo "$#"
shift
sleep 1s
done
echo The last command line argument you entered is $1.
can anyone help?

extract_usage_from_stx
extract_usage_from_stx() extract_usage_from_stx()
NAME
extract_usage_from_stx - extract "Usage:" messages from manpages written in Stx
SYNOPSIS
extract_usage_from_stx [ file file ... ]
DESCRIPTION
Process the given files, which should be manpages written in Stx, stripping away everything that is typically not included in a "Usage:"
message. If no files are given, read standard input instead.
A "Usage:" message is a message typically printed when a program is called with incorrect arguments or when help is specifically requested,
for example with a --help command line option. A "Usage:" message is typically a subset of the information provided on a command's manual
page.
The information left in the "Usage:" message by extract_usage_from_stx includes:
o the command synopsis, as given in the "SYNOPSIS" section
o the command line options, as given in the "OPTIONS" section, together with the first sentence of their description. A sentence is
taken to end at a period (.).
The output of extract_usage_from_stx is still in Stx format, which you might want to further process to produce the actual "Usage:" mes-
sage.
OPTIONS
--version, -V
Just show version information and exit.
--help, -?
Just show a short help message and exit.
SEE ALSO
stx2any (1).
BUGS
The end-condition of a sentence is too strong.
