$ echo -e "foo\nbar" > baz.txt
$ perl -p -e 's/foo\nbar/FOO\nBAR/m' baz.txt
foo
bar
How can I get this replacement to work?
You can use the -0
switch to change the input separator:
perl -0777pe 's/foo\nbar/FOO\nBAR/' baz.txt
-0777
sets the separator to undef
, -0
alone sets it to \0
which might work for text files not containing the null byte.
Note that /m
is needless as the regex does not contain ^
nor $
.
