Deleting files older than x number of years or days

I huge uploads folder and tried to delete the old files eg. files older than 3 years or files added before a certain date but for some reason it ends up deleting both new and old files.



Here are the commands I tried so far



Command 1



 find /home/user/uploads -maxdepth 1 -type f ! -newermt "2018-10-14 00:00:00" -exec rm -v ;


This command removes everything ignoring the with ! -newermt or just - newermt



Command 2



find /home/user/uploads -maxdepth 1 -mtime +1095 -type f -print -exec rm -i ;


It returned no result



Command 3



find /home/user/uploads -type f ! -newermt "2018-10-14 00:00:00" | xargs rm 


This returned an error "xargs: unmatched single quote by default quotes are special to xargs unless you use the -o option "



I can't figure out what exactly is wrong with the commands.. I'm running on a CentOS system.

  • find /home/user/uploads -maxdepth 1 -type f ! -newermt "2018-10-14 00:00:00" is correct for matching only files older than 2018-10-14 00:00:00". You say "This command removes everything" -- were there files newer than that deleted?

  • yes... it removed new files that were created after this date, instead of files created before this date

  • Make a datetst dir, e.g. md datetst && cd datetst create a file for every day of Oct. 2018, e.g for i in 1..31; do touch -d "2018-10-$i" file_$i; done, Now let's find . -maxdepth 1 -type f ! -newermt "2018-10-16" | sort and see only files corresponding to days 1-16 are selected as not newer than "2018-10-16" which is right. Does you test given different results?

  • Yes, i got the results I wanted after testing your code.. it sorted out the files created before 2018-10-16. ! -newermt sorted files before and just -newermt sorted the files modified after.. I'm going to try this with my command and post the results..

So after playing with the commands for a while this is the command that worked.



find . -maxdepth 1 -type f ! -newermt "2018-10-16" -exec rm -v ;


These flags also helped incase you're come across this situation.



-maxdepth 1 


means only files within that folder



-newermt 


used for files modified on that date or after..



! -newermt 


used for removing files before the said date.



I also added the -v flag so I would see the output of files been deleted.



Thanks for all the help this saved me a lot of time..
