Remove files within a unix shell script

[grapes12]

Afternoon,

Iam currently running a oracle datapump through a unix shell script.
The problem i have is that the dmp files have increased over time to more or less 25 dmp files perday BUT are not deleted daily. It deletes only the first 22 files leaving the other two or three in the set directory.
HOW CAN I DELETE ALL FILES WITHIN DIRECTORY
herewith my removing of files command within my unix script

 if [ -r ${EXPORTDIR}/${i}.dmp ]; then
           rm ${EXPORTDIR}/${i}.dmp
 fi

herwith example of files not deleted from directory

rw-r-----   1 oracle   oinstall 1060347904 Nov  7 01:59 /u8/datapump/MAC/MAC20.dmp
-rw-r-----   1 oracle   oinstall 1605095424 Nov  7 01:59 /u8/datapump/MAC/MAC21.dmp
-rw-r-----   1 oracle   oinstall 898039808 Nov  7 01:59 /u8/datapump/MAC/MAC22.dmp
-rw-r-----   1 oracle   oinstall 166653952 Nov  6 01:54 /u8/datapump/MAC/MAC23.dmp
-rw-r-----   1 oracle   oinstall 36659200 Nov  6 01:54 /u8/datapump/MAC/MAC24.dmp

Any assistance will be highly appreciated

HOW CAN I DELETE ALL FILES WITHIN DIRECTORY
rm -f ${EXPORTDIR}/*.dmp

BTW, what is the value of ${i} ?

Hope This Helps, PH.

The Value of ${i} belongs in the Oracle parfile, because i need the create statements for Db recovery so i do a export as well as a import into a SQL file
herewith what it looks like

create_exp_parfile()
{
        echo "USERID=system/${SYSTEM_001P}" > ${EXP_PARFILE}
        echo "DIRECTORY=datapump_mac" >> ${EXP_PARFILE}
        echo "VERSION=LATEST" >> ${EXP_PARFILE}
        [b]echo "DUMPFILE=MAC%U.dmp" >> ${EXP_PARFILE}[/b]
        echo "PARALLEL=16" >> ${EXP_PARFILE}
        echo "LOGFILE=MAC.log" >> ${EXP_PARFILE}
        echo "METRICS=y" >> ${EXP_PARFILE}
        echo "CONTENT=all" >> ${EXP_PARFILE}
        echo "SCHEMAS=MAC" >> ${EXP_PARFILE}
        echo "JOB_NAME=EXP_MAC_`/usr/bin/date '+%d%m%Y'`" >> ${EXP_PARFILE}
        echo "FILESIZE=6G" >> ${EXP_PARFILE}
        echo "REUSE_DUMPFILES=y" >> ${EXP_PARFILE}
}

the import parfile :

create_imp_parfile()
{
        echo "USERID=system/${SYSTEM_001P}" > ${IMP_PARFILE}
        echo "DIRECTORY=datapump_mac" >> ${IMP_PARFILE}
        [b]echo "DUMPFILE=${i}%U.dmp" >> ${IMP_PARFILE}[/b]
        echo "LOGFILE=IMP.log" >> ${IMP_PARFILE}
        echo "SQLFILE=MAC.sql" >> ${IMP_PARFILE}
        echo "FULL=y"  >> ${IMP_PARFILE}
        echo "JOB_NAME=IMP_MAC_`/usr/bin/date '+%d%m%Y'`" >> ${IMP_PARFILE}
}

WILL the rm -f ${EXPORTDIR}/*.dmp
still work in this case?

 

[grapes12]

I changed the script to include the following:

do_export()
{
        if [ -r ${EXPORTDIR}/${i}.dmp ]; then
           rm -f ${EXPORTDIR}/*.dmp
        fi

BUT TO NO AVAIL YOUR ASSISTANCE WILL BE HIGHLY APPRECIATEd

The out put directory still has the old files

[grapes12]

Should i leave out ?

if [ -r ${EXPORTDIR}/${i}.dmp ]; then

Because that is exactly the rm command i currently have in my script

 

[PHV]

Yes, leave it out
