Re: SED

[Stepan Kasal]

Hello,
        Gopikrishna Kannan reported a bug regarding the program:
> $ cat cmdfile
> s/.*PrintArgs.*$/#ifdef DEBUG \\n  & \\n  #endif \\n /g

This is not a bug, you've misunderstood the documentation.

The manual speaks about "\<newline>" and means the byte '\\'
followed mmediately by the byte '\n'.  IOW, backslash at the end
of a line.

So your sed program should look like this:
s/.*PrintArgs.*$/#ifdef DEBUG\
&\
#endif/

In this concrete stituation, the sed program

/PrintArgs/{
i\
#ifdef DEBUG
a\
#endif
}

may be more appropriate.  (Or you could use another tool, eg. awk.)

HTH,
