Full Discussion: How to send data to previous program (pipe)?
Top Forums Shell Programming and Scripting How to send data to previous program (pipe)? Post 303014592 by JackK on Thursday 15th of March 2018 06:57:01 AM

Both examples given by Don Cragun and Corona688 are working for me and I understand the idea behind it.
However, both those examples rely on a possibility of creating cmd1 and cmd2 from scratch, so that stdin/stdout redirection (Corona688's example) and testing file existence (Don Cragun's example) can be made.
This is, however, not possible when I have sqlplus instead of cmd1. Am I right? If yes, then my problem is still unsolved.
