Is it possible to make a virtual file using sed or awk to feed as input as a regular file?

Question

bash

I have a huge csv text file that needs 1 line to be corrected.
Let's assume that it is not possible to copy it. Is it possible to make such script of sed/awk stream editors etc. in such a way that it corrects the line on the fly and submit it as an argument to the program (loader in the database), so that it regards it as a regular csv file.

Answer 1

db_import <(awk ... myfile | some_command | ...)
