Could anyone let me know how to concatenate year and previous month in Unix Using date command

[ballardw]

Is this related to a UNIX command or within a SAS data set?

If the later, are your values numeric or character? What do you want the output to look like?

This is related to unix.

I would want the value as abc.201503.txt when i run a report in the month of April.

Is there any date command to eexecute this.

You need the GNU version of date; some UNIXes (eg AIX 5.3) have a default date command that does not include all the capabilities of GNU date.

Call it like that:

date -d "1 month ago" +%Y%m

Be careful: if you call that on March 31st, you still get 201503, because February did not have a 31st, and you land on March 3.
