How to extrapolate text from Multi-Line Command Response in Korn Shell Script

Currently writing a management menu interface for managing printers on our HP UX system.

Scripts are written in Korn Shell.

The following command
lpstat -pTERRYTST

Open in new window

returns the following:-

printer TERRYTST disabled since Apr 10 08:36 -
        new printer
        fence priority : 0

Open in new window


I need to be able to search the response for keywords to identify states.

So I need to fill a variable with 1 if the printer is disabled, another variable with 1 if its new.

No idea how to complete this in Korn Shell scripting as am very new to the language.

Help! :)

You could pass the response to a while, do read line ; evaluate the string, do stuff; done
grep to extract string.

I'm partial to perl for processing text

Using ksh, you can use system commands, including grep assignment, pattern extraction
Test to evaluate....

I've seen multi-line pattern matches, but have not mastered so could not say .....

Going line by line with the match on printer as the start of a line as an indication that the prior printer info is complete.

LPTSTAT=` lpstat -pTERRYTST `
DISABLED=0
( echo $LPTSTAT | grep " disabled " ) && DISABLED=1
NEWLPT=0
( echo $LPTSTAT | grep " new  " ) && NEWLPT=1
if [ "$DISABLED" != 0 ]
then
  echo "Disabled"

Hi noci,

This seems to work well with one exception.

The line:-
( echo $LPTSTAT | grep " disabled since" ) && DISABLED=1

Open in new window

Causes the output to be printed to screen.

Is there a way to not have this printed to the screen?

Thank you.

Use:

Open in new window


To also suppress errors:
( echo $LPTSTAT | grep " disabled since" >/dev/null 2>&1 ) && DISABLED=1
