get string out of text file after "= "
I have a text file like:

The name of the project = "Symbion centrifuge"
The name of the subsytem = "motor demon"


now i would like to read the string after the = into a variable to write it to another file.

later use like:
Code:
sed s/'PROJECTNAME'/"$projectname"/ <header.tex >temp


in $projectname i would like to have "Symbion centrifuge".

I have problems to do that...

Please help me!

try this

awk -F"=" '{print $2}' filename

or

awk -F"=" '{print $2}' filename > outputfile.txt

My first (success after a lot of errors!) try with awk (:
Code:
awk 'BEGIN {FS="="} {print $2}' header.tex | sed 's/"//g'

To put it in a variable:
Code:
VARIABLE=$(awk 'BEGIN {FS="="} {print $2}' header.tex | sed 's/"//g')
