in reply to checking particular part of string

To make it generic you would need a capture group. eg:

echo sumanna | perl -pe 's/(na$)/uc($1)/e;'

Is this what you were after?


Update: for an example with more obvious genericism try:

echo sumanna | perl -pe 's/(..$)/uc($1)/e;'

[stevieb]: james28909: what's the problem/question?
[james28909]: it is not an absolute date like "27" or "31". sometimes it is like wednesday or friday
[james28909]: and i need to format those special instances into an absolute date instead of "yesterday"
[stevieb]: ask a question on SoPW, and include at least a half-dozen examples of the input, and at least one example of expected output
[davido]: Exactly: SoPW. This isn't going to be solved easily in the CB.
[james28909]: in need "yesterday" and so on, to be absolute like "1" or "31"
[stevieb]: ...and throw some of your existing code into the equation as well, just so readers know you've given a try at it ;)
[james28909]: ok
[stevieb]: davido thanks for the link ;) I was being the typical lazy
[davido]: date parsing is hard. The more examples you can provide of the input (within reason) and expected output, the better.
