Escaping backslash char in string

[BTon15]

Hopefully this is really simple for somebody out there:

I want to build a string that I'm going to pass to the system() function command to do a Unix sed. I want my string to look like this:

-e '/\[SECTION\]/d'

i.e. I want my sed to remove a line that contains [SECTION]
The sed works fine, but I'm having problems creating the string in C. I'm doing this as follows:

strcpy (str, " -e '/\\\[SECTION\\\]/d' ");

My compiler is giving me this:

"tmp.c", line 9.22: 1506-235 (W) Incorrect escape sequence \[. \ ignored.
"tmp.c", line 9.22: 1506-235 (W) Incorrect escape sequence \]. \ ignored.

The string does seem to end up with what I want though, despite the warnings. I've tried removing some of the backslashes but this makes it worse.

Any ideas how I can compile this to avoid the warnings, whilst still ending up with the string I want?

Many thanks in advance.

Use \\ instead of \\\.
\\ = "\", then you have \[ which isn't a valid escape sequence.

This works for me...

strcpy (str, " -e '/\\[SECTION\\]/d' ");

Hope this helps.

Thanks guys - that works great.
I was sure I had already tried that before, but maybe I couldn't see the wood for the trees!
