i wanna make a shell to check core and if there is one core ,it will rename the core automatic, for example:
-rw-rw-rw- 1 pin pin 1 Mar 5 08:54 core

the core should be rename core.200303050854

i have no idea how can i do it in some simple way

Hi Gary,

I tried to write a script on the fly. Create dummy core files in subdirectories any test directory and run this against the directory. Make sure it works as you need before running it on the system.

#!/usr/bin/ksh
if [ $# -ne 1 ]
then
echo "Usage:$0 Directory"
exit 1
fi

DIR=$1
chart="
Jan-01
Feb-02
Mar-03
Apr-04
May-05
Jun-06
Jul-07
Aug-08
Sep-09
Oct-10
Nov-11
Dev-12
"

move()
{
file=$1
Month=$(ls -al $file |awk '{print $6}')
DAY=$(ls -al $file |awk '{print $7}')
TimeYear=$(ls -al $file |awk '{print $8}')

for i in $chart
do
echo $i |grep $Month > /dev/null 2>&1
if [ $? = 0 ]
then
MON=$(echo $i |awk '{FS="-";print $2}')
fi
done

echo $TimeYear |grep ":" > /dev/null 2>&1
if [ $? = 0 ]
then
HR=$(echo $TimeYear|awk '{FS=":";print $1}')
MIN=$(echo $TimeYear|awk '{FS=":";print $2}')
YEAR=$(date |awk '{print $6}')
else
HR=00
MIN=00
YEAR=$TimeYear
fi

mv $file $file.${YEAR}${MON}${DAY}${HR}${MIN}
}

for FILE in $(find $DIR -name core)
do
move $FILE
done

For this format: filename.yyyymmddhhmm

DATE=$(date +%Y +%b +%d +%H +%M)

filename.$DATE

I will agree with jsut one liner date substituion.
Do a man on date and it will tell you more for varios output format...

Guys - Read his message. He is not trying to create a file. He is renaming a file with the it's (not current)datestamp as the extension.
