My company purchased a beta program that creates backup files in the format of backup.<date>. However they are put in different locations on the drive. Id like to be able to create a script to remove all files that start with backup. without looking through each folder.

Now will that way search the whole drive and delete all files with the backup name?

Can I prompt it for permission the first time and then delete it automatically afterwards?

Can I limit it to where it should search?

to change which path is searched just replace / with whatever directory you want it to check. if you have sudo installed you can just add the sudo command to the front of the find command to run it as root, it will ask you to authenticate when you run it.

OK, I have files located in each month of the year and I wanted to delete all files with the backup in each month.  I dont want to browse and delete.

find / -type f -iname 'backup*' -exec rm -i -f -r {ls.. \January\backup}
find / -type f -iname 'backup*' -exec rm -i -f -r {ls.. \February\backup}
...

Am I off track here or is there an easier way??

Thanks!

CyberIT - the -r and -f commands are only necessary if you wanted to delete a directory and it's contents.

-type f
restricts you to finding only regular files, not directories or links or sockets,
see
man find

You can use a for loop to do for each month.So use something like this:

for month in January Febuary March April May June July August September October November December
do
find / -type f -iname 'backup*' -exec rm -i -f {ls.. \\$month\\backup}
done
