AWK/SED. How to remove parentheses in simple text file

Question

I have a text file looking like this:

(-9.1744438E-02,7.6282293E-02) (-9.1744438E-02,7.6282293E-02)  ... and so on.

I would like to modify the file by removing all the parenthesis and a new line for each couple so that it look like this:

-9.1744438E-02,7.6282293E-02
-9.1744438E-02,7.6282293E-02
...

A simple way to do that?

Any help is appreciated,

Fred

Answer 1

I would use tr for this job:

cat in_file | tr -d '()' > out_file

With the -d switch it just deletes any characters in the given set.

To add new lines you could pipe it through two trs:

cat in_file | tr -d '(' | tr ')' '\n' > out_file

Answer 2

As was said, almost:

sed 's/[()]//g' inputfile > outputfile

or in awk:

awk '{gsub(/[()]/,""); print;}' inputfile > outputfile
