Code:

TIME_DATE_SPLIT=`date +%Y-%m-%d-%p`

TIME_CHECK="`(echo $TIME_DATE_SPLIT | cut -d "-" -f 4)`"

#######FUNCTION START########
PREVIOUS_DATE_FUNCTION()
{

date '+%m %d %Y' | 
{ 
read MONTH DAY YEAR
DAY=`expr "$DAY" - 1` 
case "$DAY" in 
        0) 
           MONTH=`expr "$MONTH" - 1` 
                case "$MONTH" in 
                        0) 
                           MONTH=12 
                           YEAR=`expr "$YEAR" - 1` 
                        ;; 
                esac 
        DAY=`cal $MONTH $YEAR | grep . | fmt -1 | tail -1` 
esac 
    PREVIOUS_TEMP_DATE=$YEAR-$MONTH-$DAY
    echo $PREVIOUS_TEMP_DATE
}

}
#######FUNCTION END########
TIME_CLOCK="AM"

if [ $TIME_CHECK = $TIME_CLOCK ]; then
    
PREVIOUSDATE="`PREVIOUS_DATE_FUNCTION`"   #FUNCTION CALL#
   
tempfile=CANCEL_FILE_$PREVIOUSDATE_AM

Problem here is that $PREVIOUSDATE value is null.I am not getting the tempfile=CANCEL_FILE_27-06-2012_AM
I am getting

Code:

tempfile=CANCEL_FILE__AM

column

COLUMN(1)						    BSD General Commands Manual 						 COLUMN(1)

NAME

     column -- columnate lists

SYNOPSIS

     column [-tx] [-c columns] [-s sep] [file ...]

DESCRIPTION

     The column utility formats its input into multiple columns.  Rows are filled before columns.  Input is taken from file operands, or, by
     default, from the standard input.	Empty lines are ignored.

     The options are as follows:

     -c      Output is formatted for a display columns wide.

     -s      Specify a set of characters to be used to delimit columns for the -t option.

     -t      Determine the number of columns the input contains and create a table.  Columns are delimited with whitespace, by default, or with
	     the characters supplied using the -s option.  Useful for pretty-printing displays.

     -x      Fill columns before filling rows.

     column exits 0 on success, >0 if an error occurred.

ENVIRONMENT

     COLUMNS  The environment variable COLUMNS is used to determine the size of the screen if no other information is available.

EXAMPLES

	   (echo "PERM LINKS OWNER GROUP SIZE MONTH DAY HH:MM/YEAR NAME"; 
	   ls -l | sed 1d) | column -t

SEE ALSO

     colrm(1), ls(1), paste(1), sort(1)

HISTORY

     The column command appeared in 4.3BSD-Reno.
