sed across multiple files
I've got a bunch of files (40 or so) and in each there is a substitution I need to perform.
I execuet the following sed command but it just make the changes to the screen without affecting the original file.
sed "s/, LA/,LA/g" *
(All files in the directory need this update).
So I tried redirecting...
for x in *
do
sed "s/, LA/,LA/g" $x > new_$x
done
And that worked. But I'm not sure about renaming the files back to what they were. mv obviously doesnt' like the wildcards and I'm not sure how to convert back.
I'd also like to know if there is a way to do this without piping to a new file...
