Changing the date format
Hi,

I know there is a Q/A section and lots of posts regarding date command here. I am sorry to start a new thread. I am very new to shell scripting (actually i am working on my first program), so please forgive my ignorance. I could not find an answer to my problem else where so i posted it here.
I appreciated if anyone would refer me to a source where i can get my answer or give me some suggestions on how to resolve the matter.

This is what i need to do:

I am trying to use a shell script in Linux to read the current time and change the format to M_D_YYYY.
then the program needs to search the current directory for a file named "InfoM_D_YYY" (for example 'Info6_7_2005' ), read the file and write the data in separate variables.
When i use the date command, the out put is formated as follows:

Tue Jun 7 12:55:12 UTC 2005

I do nto know how i can change this format to M_D_YYYY and save in a variable which i can later ue to search for a file named InfoM_D_YYYY.

Again, I am sorry if this question is repetitive.

Thank you,

Nina

NEWS(1) 							   USER COMMANDS							   NEWS(1)

NAME

       news - display system news

SYNOPSIS

       news [-adDeflnpvxs] [[article1] [article2] ..]

DESCRIPTION

       The  news command keeps you informed of news concerning the system.  Each news item is contained in a separate file in the /var/lib/sysnews
       directory. Anyone having write permission to this directory can create a news file.

       If you run the news command without any flags, it displays every unread file in the /var/lib/sysnews directory.

       Each file is preceded by an appropriate header. To avoid reporting old news, the news command stores a currency time. The news command con-
       siders your currency time to be the date the $HOME/.news_time file was last modified. Each time you read the news, the modification time of
       this file changes to that of the reading. Only news item files posted after this time are considered unread.

OPTIONS

       -a, --all
	      Display all news, also the already read news.

       -d, --datestamp
	      Add a date stamp to each article name printed. this can only be used with the -nl flags.

       -D, --datefmt <fmt>
	      Specify a date format, see the strftime(3) man page for more details.  the default format is (%b %d %Y)

       -f, --newsdir <dir>
	      Read news from an alternate newsdir.

       -l, --oneperline
	      One article name per line.

       -n, --names
	      Only show the names of news articles.

       -p, --page
	      Pipe articles through $PAGER or more(1) if the $PAGER environment variable is not set.

       -s, --articles
	      Reports the number of news articles.

MAINTAINER OPTIONS

       -e, --expire #
	      Expire news older than # days.

       -x, --exclude a,b,c
	      A comma separated list of articles which may not be expired.  if a file named .noexpire exists  in  the  /var/lib/sysnews  direcory,
	      filenames are read from it also. names in this file may be comma separated, and/or one per line.
