Month manipulation in script

[qzq17j]

Please respond, how can I manipulate month, for example I want to run a script every month by extracting data of the previous month from a file. I know how to code overlapping year once I know how to find out previous month and previous year from the current date. Any suggestions ?

Just a thought, but why not do it the easy way. I assume you are storing the file as something like "file2001-01". So why not make a symbolic link "ln -s file2001-01 lastmonth". Then in your script just look for the file "lastmonth". At the end of the script, delete the "lastmonth" file and create a new symbolic link.
