how can i pick the latest log file as per below

in the below .. i want to pick the latest logfile which is having JPS.PR inside..

that means i want particularly "spgport040408041223.log:@@@@@@@@ 04:13:09 Adding: JPS.PR."
which is latest among these..
is it possible to compare the current time with logfile time ?

CPU & Memory Just use tail command with your command

If your command

grep -i adding spg* | grep JPS.PR | grep -iv equation

is fetching the right set of file and if its just a matter of picking up the latest file then use tail -1 with your command ...


the command will be
grep -i adding spg* | grep JPS.PR | grep -iv equation | tail -1


I think this must work.....

Command we tried using to grep ERROR from lastest 1 log files from 5 logs files available in that particular directory is:
grep ERROR 'ls -ltr | tail -1'

but this command is not working.. for me its saying.. cannot open DistributeImageFilesToTarget_10_dataLocations_PhillipinesDataLocations.xml.log

Try "ls -1tr" in place of "ls -ltr". The parameter "-1" (-one) just displays the filename as distinct from "-l" (-ell) which gives more detail and confuses your script.
