Hi All,
I have made a script to compare dates of files with todays date
as below


Code:
datecalc()
{
if [ $1 = "Jan" ]
then
return 1;
elif  [ $1 = "Feb" ]
then
return 2;
elif  [ $1 = "Mar" ]
then
return 3;
elif  [ $1 = "Apr" ]
then
return 4;
elif [ $1 = "May" ]
then
return 5;
elif  [ $1 = "Jun" ]
then
return 6;
elif  [ $1 = "Jul" ]
then
return 7;
elif  [ $1 = "Aug" ]
then
return 8;
elif [ $1 = "Sep"
then
return 9;
elif  [ $1 = "Oct" ]
then
return 10;
elif  [ $1 = "Nov" ]
then
return 11;
elif  [ $1 = "Dec" ]
then
return 12;
fi
}
cd /CP2_logs/wls21/SAS/MDCR/Applicationlogs/WLS13
v1=`ls -lrt | awk '{print $6,$7,$8,$9}'| egrep  "gz$" |  egrep "MDCR.*" | wc -l`
v2=`date | awk '{print $2}'`
v3=`date | awk '{print $3}'`
datecalc $v2
v4=$?
i=1
while [ $i -le $v1 ]
do
A[$i]=`ls -lrt | awk '{print $6,$7,$8,$9}'| egrep  "gz$" |  egrep "MDCR.*" | awk '{print $1}' | head -$i | tail -1`
B[$i]=`ls -lrt | awk '{print $6,$7,$8,$9}'| egrep  "gz$" |  egrep "MDCR.*" | awk '{print $2}' | head -$i | tail -1`
C[$i]=`ls -lrt | awk '{print $9}'| egrep  "gz$" |  egrep "MDCR.*" | awk '{print $1}' | head -$i | tail -1`
echo ${A[$i]}
echo ${B[$i]}
echo ${C[$i]}
i=`expr $i + 1`
done

but while running it on solaris 5.8 with kornshell its giving error
related to arrays as

Code:
A[1]=May: not found
B[1]=5: not found
C[1]=MDCRClient_Refactored.log.1.06-05-12.gz: not found
bad substitution

while same script is working on linux with bash

please suggest with this

dp

DP(8)								     [nmh-1.5]								     DP(8)

NAME

       dp - parse dates 822-style

SYNOPSIS

       /usr/lib/mh/dp [-form formatfile] [-format string] [-width columns] [-version] [-help] dates ...

DESCRIPTION

       Dp  is  a  program that parses dates according to the ARPA Internet standard.  It also understands many non-standard formats, such as those
       produced by TOPS-20 sites and some UNIX sites using ctime(3).  It is useful for seeing how nmh will interpret a date.

       The dp program treats each argument as a single date, and prints the date out in the official 822-format.  Hence, it  is  usually  best	to
       enclose each argument in quotes for the shell.

       To  override  the  output  format  used by dp, the -format string or -format file switches are used.  This permits individual fields of the
       address to be extracted with ease.  The string is simply a format string and the file is simply a format file.  See  mh-format(5)  for  the
       details.

       Here is the default format string used by dp:

	    %<(nodate{text})error: %{text}%|%(putstr(pretty{text}))%>

       which  says  that  if an error was detected, print the error, a `:', and the date in error.  Otherwise, output the 822-proper format of the
       date.

FILES

       $HOME/.mh_profile	  The user profile

PROFILE COMPONENTS

       None

SEE ALSO

       ap(8), Standard for the Format of ARPA Internet Text Messages (RFC-822)

DEFAULTS

       `-format' default as described above
       `-width' default to the width of the terminal

CONTEXT

       None

BUGS

       The argument to the -format switch must be interpreted as a single token by the shell that invokes dp.  Therefore, one must  usually  place
       the argument to this switch inside quotes.
