Description Thierry Vignaud 2010-09-24 15:05:04 UTC

Description of problem:
For options that are known to output quite a lot of data, rpm shoulduse $PAGER, $LESSOPEN and the like in order to not flood the console.
Eg:  rpm -q --changelog, rpm -qa, ...

Version-Release number of selected component (if applicable):
rpm-4.8.1-5.fc14.x86_64

How reproducible:
always

Steps to Reproduce:
1. run "rpm -q --changelog rpm"
2.
3.
  
Actual results:
console is flooded and only

Expected results:
A nice enhancement would be to automatically use more/less/... like eg man does

Sorry but not going to happen. Rpm is not the kind of interactive tool as eg 'man' is, and automatic pager invocation is IMO nothing but annoying distraction to unix tradition. Things like 'ls' dont use automatic paging either.

Sorry to hear this.

I will try one last argument : think of "rpm -q --changelog" as "git log".
Both provides the same kind of data (history).

The later is more usefull in the sense that when it detects an interactive shell, it automatically uses a pager.
