Eg:

if [ $int1 = $int2 ]...

echo $cfg | grep ".log$" >/dev/null 2>&1

flag=`echo $?`

if [ $flag -eq 0 ]; then

The solution suggested by "michaelrozar17" works. .. But with a small change:

odt=`date +%d/%m/%Y -d "25OCT2008"`

echo $odt # You will get 25/10/2008

quick solution:

var1=apple,boy,chris

var1=`echo $var1 | sed "s/,/','/g"`

var1=`echo "'"$var1"'"`

echo $var1 # Now it holds : 'apple','boy','chris'

Try with:

find -atime +2 -name "*"
