Finding Newer Files

Although find provides flags to locate files newer than certain days (-mtime -2), it is not fine grain enough to allow user to specify based on user-defined timestamp. Below script will touch a temporary file with specific timestamp and find will make use of it as a reference by using the "-newer" flag. FYI, this has been tested on Solaris

#! /bin/ksh

if [ $# -ne 2 ]; then
        echo "Usage: $0 directory time"
        echo "       time - a decimal number of the form: [[CC]YY]MMDDhhmm[.SS]"
        exit 1
fi
directory=$1
timestamp=$2


if [ ! -d $directory ]; then
        echo "Error. Directory $directory does not exist"
        exit 2
fi


tmpfile="/tmp/${0##*/}-$$"
touch -t $timestamp $tmpfile > /dev/null 2>&1
if [ $? -ne 0 ]; then
        echo "Error. Incorrect time format [[CC]YY]MMDDhhmm[.SS]"
        exit 2
fi


trap "rm -f $tmpfile; exit 0" EXIT


find $directory -newer $tmpfile -local -mount -type f
