This n is invalid--------------------------^^^
You should add a backslash before each slash
that is not used as a separator for the s command.
E.g.
s/I want to substitute the \/ character/with the _ character/
s/\/\/\//three slashes/
You can also use a separator of choice for the s command.
That is:
s/foo/bar/ is equivalent to s@foo@bar@
is equivalent to sAfooAbarA
is equivalent to s1foo1bar1.
keep in mind, that our sed might not be
totally compatible with GNU sed.
HTH, Nikos
