My system create files everyday in specific file system.

so I want to make a script which find out specific files created in specific time
and delete it after backup to other directory.

and copy that file to backup directory and delete the original.

The key is to use touch to create two reference files and then use the -newer option of find.

#!/usr/bin/sh


TDIR=${TMPDIR:-/var/tmp}
typeset T1=${TDIR}/Ref_1.${$}
typeset T2=${TDIR}/Ref_2.${$}
typeset BKDIR=/xxx/Backup
typeset SRCDIR=/xxx/yyy
typeset -i STAT=0
typeset FNAME=""
typeset DESTNAME=""
cd ${SRCDIR}
STAT=${?}
if [[ ${STAT} -ne 0 ]]
then
echo "Can't cd to ${SRCDIR}" >&2
exit ${STAT}
fi
touch -t 200607090659.59 ${T1}
touch -t 200607092100.01 ${T2}
find . -type f \( -newer ${T1} -a ! -newer ${T2} \) -print | while read FNAME
do
DESTNAME="${DESTDIR}/${FNAME}"
if [[ -f "{DESTNAME}" ]]
then
echo "${DESTNAME} exists; not copied" >72
else
cp -p "{FNAME}" "${DESTNAME}"
STAT=${?}
if [[ ${STAT} -eq 0 ]]
then
rm -f "${FNAME}"
else
echo "Cp of ${FNAME} failed; status ${STAT}" >&2
fi
fi
done
rm -f ${T1} ${T2}
exit ${STAT}


man find, touch for details.
