Question

If I am writing a bash script to do an inplace edit of a bunch of files and the line I want to change is something like:

#include <foo/bar.h>

to

#include "bar.h"

what would the syntax be?

old='#include <foo/bar.h>'
new='#include "bar.h'
perl -pe -i.bak 's/$old/$new/g' baz.h

Answer 1

If all the files are in the same directory, this should work:

sed -e 's@#include <foo/bar.h>@#include "bar.h"@' -i *.c
