Keep the funtions at the start of your code
Code:
#!/bin/ksh

monthname()
{
case $1 in
01) _MONTH=Jan ;; 02) _MONTH=Feb ;;
03) _MONTH=Mar ;; 04) _MONTH=Apr ;;
05) _MONTH=May ;; 06) _MONTH=Jun ;;
07) _MONTH=Jul ;; 08) _MONTH=Aug ;;
09) _MONTH=Sep ;; 10) _MONTH=Oct ;;
11) _MONTH=Nov ;; 12) _MONTH=Dec ;;
esac
}

six2date()
{
temp=${1#??}
year=$(( ${1%"$temp"} + 2000 ))
monthname "${temp%??}"
day=${temp#??}
_DATE=$_MONTH-$day-$year
}

fourteen2date()
{
temp1=${1#????}
year=${1%"$temp1"}
temp2=${temp1#??}
monthname ${temp1%"$temp2"}
temp3=${temp2##??}
day=${temp2%"$temp3"}
_DATE=$_MONTH-$day-$year
}

cd /tmp/sa/script

file=TP_xx_yy_032307.txt
suffix=${file##*.}
name=${file%_*}
temp=${file%."$suffix"}
date=${temp#"$name"_}

case ${#date} in
6) six2date ${date} ;;
14) fourteen2date ${date};;
esac

newfile=${name}_$_DATE.$suffix
mv "$file" "$newfile"

mv "$file" "$newfile"

I was working on that,i mean shuffling the functions to be top...and i seem to get some output...

when i give file input as
output
BP_x_yy_20070323134501.dat ==> BP_x_yy_Mar-23-2007.dat
TP_xx_yy_032307==> TP_xx_yy_-07-2003.txt

The first file output seems to be fine....but the six2date is failing in date conversion..

Perfect Anbu....Thats really great...and i would like to thank Johnson for the code...it is working as expected....

All i need is now ,instead of specifying the file one by one..i will put these files inside a a folder and call them in a loop..

BP_aaa_bbb_20070323050007.dat
BP_ccc_ddd_032307.dat
BP_aa_bb_032307.dat
BP_dd_ee_032307.dat
BP_ff_gg_032307.xls
BP_xx.yy_20070323134501.dat
BP_ss_pp_20070323030002.dat

can it be done something like this

cd /tmp/ss/files

for file in *
do
suffix=${file##*.}
name=${file%_*}
temp=${file%."$suffix"}
date=${temp#"$name"_}
done

And Anbu,the date program that you had sent me,can it be tweaked this way,

BP_xx_yy.dat ....i want the date protion to be inserted like this BP_xx_yy_Mar-23-2007.dat instead of appending at the end....can it be done this way

dt=$( date "+%b-%d-%Y" )
for i in *
do
suffix=${i##*.}
mv $i ${i}"_${dt}"."$suffix"
done

When i run the above code for the first time,it appends with todays date.Something like this

Input : BP_xx_yy.dat
Ouput : BP_xx_yy_Mar-29-2007.dat

But when i re-run the program,instead of overwriting the date portion,it is appending the date once again.

Input:BP_xx_yy_Mar-29-2007.dat
Output : BP_xx_yy_Mar-29-2007_Mar_29_2007.dat

I tried with many combinations with the mv command but in vain...please help me in this regard...

Thanks,
Kumar
