Shell Programming and Scripting

Hello All,

A part of my very basic perl code requires me to read a single value from a text file.

The file output is the following:

Code:

Reading image ... done
IMAGEREGION=0x0x0-256x162x256
VOXELDIMENSION=0.9375000000x1.2000000477x0.9375000000
VOXELNUMBER=10527001
VOXELVALUESSUM=17106334539.8829383850
VOXELVALUESMIN=0.9334983230
VOXELVALUESMAX=44340.0000000000
VOXELVALUESMEAN=1624.9960021741
VOXELVALUESMEDIAN=695.7995605469

Am trying to read value 44340 alone and assign it to a variable.

Any help will be very much appreciated.
Many thanks

use below

Code:

perl -lanF'=' -e  '/MAX/ and print $max=$F[1] ;'

if you just want the integer part as mentioned:

Code:

perl -lanF'[=.]' -e  '/MAX/ and print $max=$F[1] ;'

Try:

Code:

open FH,"file.txt";
while(<FH>) { print int($2) if /(VOXELVALUESMAX=)(.*)/; }
close FH;

or Using awk,

Code:

awk -F=. '/MAX/ { print int($2); }' file

if you want the int part

Code:

perl -lanF'=' -e  '/MAX/ and print $max=int($F[1]) ;'

thank you all for your replies but am still facing some issues
1. am trying to write it within code itself so for some reason whenever I use the single line bit of code from ahmad.diab and anchal_khare I get Bad name after lanF' I think am typing it in wrong.

2. The awk portion from you dennis jacob gives me just 4 digits and not 5. I get 4340 instead of 44340
Also for some reason the perl portion of reading in the file, at least doesnt give me any errors but am stuck at printing the value, how do I assign it to a variable

Apologies all, you have been very helpful but am a real novice here.

Any other suggestions will be very appreciated.
Thanks

put a sample of you input data and your code.
