Shell Programming and Scripting

Hi all;

Here is my file:

V1.3=4
V1.4=5
V1.1=3
V1.2=6
V1.3=6

Please, can you help me to write a script shell that counts the sum of values in my file (4+5+3+6+6) ?

Thank you so much for help.
Kind regards.

Hello chercheur111,

Could you please try following and let me know if this helps you.

awk -F"=" '{SUM=SUM?SUM+$NF:$NF} END{print "SUM = "SUM}'  Input_file

Output will be as follows.

SUM = 24

Thanks,
R. Singh

This could be simplified a little bit to:

awk -F"=" '{SUM+=$NF} END{print "SUM = "SUM}'  Input_file

If you want to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk or nawk .
