My question is similar to this one but the answers don't address how I would like to solve it in my case:

Background: I have two computers generating experimental results that are filed in directories based on timestamps. E.g.:

190525184212  190525184433  190525185428  190525194813 ...

I am moving the results to one host computer using rsync (with --remove-source-files) but since it is possible for two experiments to start during the same second it is possible that this will overwrite results already on the host computer.

What I would like is it append to the directory names when they are identical. Something like this:

190525184212  190525184433  190525184433_1  190525185428  190525194813 ...

(The alternative would be for each machine to add its own unique id to the directory names to avoid conflicts but that means hashing the hostname or something and I am not expecting many conflicts so the solution above would be more appealing to me)

I'm guessing I have to write some kind of bash script (like this one but it was down-voted)? But was hoping for a ready-made solution.


Footnote: The sub-directories are not all in one main directory as implied above. There are more than one sub-directory so solutions have to be recursive.

  • Not getting any feedback, I'll assume this is not a good idea and do the merge operation in Python. – Bill May 26 '19 at 19:47
  • the title of your post is convoluted ... a simpler title may attract more attention .... something like how do I merge identically named files? – jsotola May 26 '19 at 20:31

    @jsotola They don't want to merge the files though, they want to rename them if they already exist. – Sparhawk May 26 '19 at 23:56
  • rsync with "no clobber" sounds (to me) like one should use "cp" with appropriate command options, something like: cp --backup=existing -t <src> <dest> – Theophrastus May 27 '19 at 0:13

    If you are looking to distinguish 'same name' from 'same file' then why not just script a find, compare file names and rename any files with the same names but different MD5 or SHA256 hashes? – bu5hman May 29 '19 at 17:56
