Cron job to replace file according to system date

[erictherev]

Hello all,

I am totally new to bash scripting and cron, so please forgive my lack of knowledge.

I am trying to create a cron job that will (most likely via a bash script) compare file names to the system date and replace a file with one that has today's date in the name. This needs to be a job that would run once daily indefinitely.

For instance, I have the following files:

1217.html
1218.html
1219.html
today.html

The system date today is 12/18, so the idea would be to overwrite today.html with 1218.html.

I need to not have the year in the file name, so I would not be able to name the files 12182019.html or 121819.html.

I am sure that this has been addressed in other threads, but I don't know how to word a search to get the results needed. Pointing me in the right direction as far as where to look for ideas on how to do this would be greatly appreciated.
