UNIX for Dummies Questions & Answers

I have a file named "file1" with contents as shown below:

name(abc) age(123)
empid(a123) degree(graduate)
.
.
.
.

Now suppose I know that the format of my file is as above but I don't know the contents within () ie. as if the file to me is like this
name(???), age(???) etc. How do I extract the contents within () and store it in a variable?
Please help me if possible with a sample code!

sample,

Code:

echo "name(abc) age(123)" | sed 's/^.*(\(.*\)).*(\(.*\))/\1 \2/'

hey please try this out

while read name
do
i=0
name[$i]=`echo $name | sed 's/^.*(\(.*\)).*(\(.*\))/\1/'`
age[$i]=`echo $name | sed 's/^.*(\(.*\)).*(\(.*\))/\2/'`
i=`expr $i + 1`
done < filename

hi

can you tell me if it is a single line file or with line breaks..

It is a multi line file and the inbetween spaces are also not constant ie. name(???), age(???) can be separated by single space/tab/new line.

hey manas,

I didn't understand why the while loop is required?

I tried the following way. It isn't giving any error but no outputs also

x=`nawk -F 'NR == 1 {print $1}' | sed 's/^.*(\(.*\))/\1/'`
echo "$x"

The nawk part is working. I have checked it with echo command. So the input to sed is something like name(abc).

Can you please clarify where I am going wrong?

Input stream is missing
