get string out of text file after "= "

Shell Programming and Scripting
1

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:

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!

look up awk and setting the delimiter (FS)

3

try this

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

or

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

4

My first (success after a lot of errors!) try with awk (:

awk 'BEGIN {FS="="} {print $2}' header.tex | sed 's/"//g'

To put it in a variable:

VARIABLE=$(awk 'BEGIN {FS="="} {print $2}' header.tex | sed 's/"//g')
5 
read line < infile
projectname="${line#*= }"
6 
cat filename |sed 's/.*="\(.*\)".*/\1/' > output.txt
7 
sed -n '1s/.*= //p' infile
8 
while IFS="=" read a b
do
    echo $a
    echo $b
done <"file"

Misread your post, I thought you wanted to get rid of the double quotes around the value as well, since it appears you don't want to do that, this should do the job:

sed 's/.*=\(.*\)/\1/' < <inputfile>
