Re: GREP doesn't work

Good observation. So, I thought I would check out your theory.

STRQSH
$
Cd /production/goanywhere/logs/2014-03-03
$
find . -type f | xargs grep QSYSOPR4

it lists 5 files that contain this text, then it just sits there
awhile. Probably at least a minute or two and the $ finally returns.
Interesting since there are only 5 files in the directory. What is
taking so long for the $ to appear?

As you can tell, I don't use QSHELL very much and forgot to pay
attention to the $.

My first reaction was... But that is quite near the opposite of what I was experiencing!

So I just now tested using a typical grep request that I might make. What I noticed this time, is that my issue was my own _confusion_, based on how long the _initial shell prompt_ takes to appear after I first enter QSH; my prompt is not the $, but reverting back to $ makes no difference.

The effect merely *appears* to be that grep ran asynchronously, because the initial prompt from *before* issuing the grep had not yet been presented. Thus when eventually the prompt is presented, that text appears to prefix the returned data; i.e. making the grep seem to have returned control to the shell, whilst the grep work was still being performed. That combined with the next prompt also being presented slowly, allowed me to misinterpret the effects.

So I guess my only concern is why the initial prompt is taking such a ridiculously long time to appear on v7r1, as compared to earlier releases.
