Shell Programming and Scripting

Guys

Im checking some of my files for errors. I want to be able to find text and make sure it's located on the right place.

Example

Chapter 1
TEXT LKJ
TEXT 12Y
more and more text
Chapter 2
TEXT 34G
TEXT HHG
more and more text
Chapter 3
TEXT FG45
TEXT 11w
more and more text

many more Chapters

To ensure that "TEXT HHG" is located on the right chapter,
I been doing grep -B 100 -A 100 "TEXT HHG" file

but it's still a pain
is there a way I can check if "TEXT HHG" is between Chapter 2 and Chapter 3 ?

Thank you
Tony

Yes indeed, use sed

Put this inside chapters.sed

Code:

#!/usr/bin/sed -nf

/Chapter 2/,/Chapter 3/ {
   /TEXT HHG/p
}

chmod the script to make it executable, and assuming that your text is in file, run

Code:

./chapters.sed file

and this should do the trick.

EDIT: You could actually make this more generic. Put this into chapters.sh

Code:

 #!/bin/sh

 chap_1=$1
 chap_2=$2
 search=$3

 sed -n "/Chapter $1/,/Chapter $2/ {
    /$3/p
 }" file

Then call the script with

Code:

chapters.sh 2 3 "TEXT HHG"

This is then reusable for other searches.

Perhaps use grep...

grep -nE 'Chapter 2|Chapter 3|TEXT HHG' file

...gives output like....

43:Chapter 2
88:TEXT HHG
106:Chapter 3

Thank you
Works Great
