Hi,
This is Pavan,

Every month we do a build for that we create a folder like 202107 for current month., then copy some files from previous month build 202106. Currently we're doing it manually.

Now we are automating the process. So for the current month build I'll create a folder with the command "$"(date +%Y%m)"". So how can i get to previous build directory. Can anyone tell exact command to use.

Thanks,
Pavan Kumar

Read the "Question Guidelines" link in my posting signature. We're happy to help you, but asking us to write scripts for you and look up exact commands is fairly rude. Why don't you start by showing us what YOU have done/tried/written so far, and tell us where you're stuck?

There are thousands of bash scripting tutorials and date examples you could find with a brief internet search; have you done any research?

I'll bite, and offer a quick, general solution.

Assuming that...

1) this is a script for a modern shell like bash or zsh, and
2) the directories are named so that they sort naturally, and
3) there are no extraneous entries that could interfere with the sorting

...then you should be able to use simple shell globbing to match and capture all (or a range) of the directory names into an array, with the final array entry containing the one you want. There's no need to even worry about targeting exact dates with this technique.

I'll leave the implementation details for the user to research.
