Reading a line from a file

[dude70_1]

Hi Guys,

I have a file where I have some properties. I want to read their value by property name like..

p1=value1
p2=value2

one time I want to read value of just p2. How do I do it?

Thanks in adv.

Hi Dude70,

try this:

grep "^p2=" file

do you want to set the variable in the script or just see, what is it?

the value you get by:
string=`grep "^p2=" file`
value=`expr "${string}" : ".*=\(.*\)"`

greetings,

Michael

Hi Dude70,

you have accidently opened two threads for the same problem. Maybe you should ask that the second thread be deleted.

greetings,

Hi,

Perhaps you shuld make een array. Then you can read all of your variables.

Succes

cat filename | awk -d "=" '{ print $2}'
