[code] Automatic File Input
i have got many files like this in my folder temp(say)
imp_02042008.txt for date 02-04-2008
imp_03092009.txt for date 03-09-2009
imp_25112009.txt for date 25-11-2009
...................
........
in some folder.
and one of my shell code uses one of the above files based on date.
for example for todays date it should pick the file imp_25112009.txt
for tomorrows date it should pick the file like imp_26112009.txt
My code is like below one:
print substr($1,4,3),"",substr($2,22,8) inputfile.txt>outputfile.txt

This code should run on day to day basis.
What i want is a code to pick up the file (eg..imp_26112009.txt) automatically from folder temp based on day.. i.e, for a given day particular file should be taken as input in my code...
pls help me in this regard..

shtool-mdate

SHTOOL-MDATE.TMP(1)					      GNU Portable Shell Tool					       SHTOOL-MDATE.TMP(1)

NAME

       shtool-mdate - GNU shtool pretty-print last modification time

SYNOPSIS

       shtool mdate [-n|--newline] [-z|--zero] [-s|--shorten] [-d|--digits] [-f|--field-sep str] [-o|--order spec] path

DESCRIPTION

       This command pretty-prints the last modification time of a given file or directory path, while still allowing one to specify the format of
       the date to display.

OPTIONS

       The following command line options are available.

       -n, --newline
	   By default, output is written to stdout followed by a "newline" (ASCII character 0x0a). If option -n is used, this newline character is
	   omitted.

       -z, --zero
	   Pads numeric day and numeric month with a leading zero. Default is to have variable width.

       -s, --shorten
	   Shortens the name of the month to a english three character abbreviation. Default is full english name. This option is silently ignored
	   when combined with -d.

       -d, --digits
	   Use digits for month. Default is to use a english name.

       -f, --field-sep str
	   Field separator string between the day month year tripple. Default is a single space character.

       -o, --order spec
	   Specifies order of the day month year elements within the tripple. Each element represented as a single character out of ``"d"'',
	   ``"m"'' and ``"y"''. The default for spec is ``"dmy"''.

EXAMPLE

	#   shell script
	shtool mdate -n /
	shtool mdate -f '/' -z -d -o ymd foo.txt
	shtool mdate -f '-' -s foo.txt

HISTORY

       The GNU shtool mdate command was originally written by Ulrich Drepper in 1995 and revised by Ralf S. Engelschall <rse@engelschall.com> in
       1998 for inclusion into GNU shtool.
