how to compare the files between two servers file systems in unix

[Kiran26]

Hi All,

We have recently migrated our SAS environment to PC2.O servers.  After successful migration to new servers we are facing the data mismatching between old and new servers. This is because we performed rsync from old to new servers around some tera bytes of data and after rsync is completed again users have created/updated the datasets which are missing in new servers now.  We are comparing manually and it is very painful to identify the missing files/datasets from old servers to new server.

If we have any script which can identify the missing files form old server to new server that would be of great help. Please help us.

Typically I would say that is for an operating system tool to compare directory structures but which one(s) might be usable depends on the Operating system involve.

If you want to use SAS you should be able to pipe the results of a directory listing command into a data set getting the names and dates and such for each server set. Clean up the paths and you might have a relatively simple compare of the contents of two data sets

Just repeat your rsync. It will only copy new files (with the correct settings of parameters, of course).
