Need to Change File name in Script

I have to ftp 4 files from one server to another.
These files are formatted as zcced.f1.o1.d333.d3333
the only difference with these files is the last four digits.
Once I ftp them I have to take the file with HDr 166 as the begin line and change it to a zcced.f1.ou.d333.d3333.

The other 3 files I will delete.
Can anyone help me on how to change to file name?
Right now I'm using the find command which gets me the file I want but I don't know how to use that info to change to file name.

Yes. You can use find command to find the file and use to change the name of filename as,

find <path> -type f -name "filename" -exec cp {} <newfilename> \;

where,

collected file is noted as {}
-exec cp {} <newfilename> \;

will copy the filename. If you want to fully move then use mv command there.

You can use any shell command on -exec <command> <filename> \; there.

HTH.
