Thanks. But I also want to remove the #include statements from
the source files, and have one instance of #include for the header
file into which the #includes are collected. Sorry for being so
picky.
I've never used uniq, though I've seen it in the man page listing...
Anyway, the command pipe above isn't working...
`grep include *.c` shows all my includes. `grep include *.c | uniq -d`
isn't showing any.
Here are the contents (in my test, all I have are #include statements):
ex1.c:#include <1a.h>
ex1.c:#include <2.h>
ex1.c:#include <3.h>
ex1.c:#include <4.h>
ex1.c:#include "5.h"
ex1.c:#include <1b.h>
ex2.c:#include <1c.h>
ex2.c:#include <2.h>
ex2.c:#include <3.h>
ex2.c:#include <4.h>
ex2.c:#include "5.h"
ex2.c:#include <1d.h>
ex3.c:#include <1e.h>
ex3.c:#include <3.h>
ex3.c:#include <4.h>
ex3.c:#include "5.h"
ex3.c:#include <1f.h>
ex4.c:#include <1g.h>
ex4.c:#include <4.h>
ex4.c:#include "5.h"
ex4.c:#include <1h.h>
ex5.c:#include <1i.h>
ex5.c:#include "5.h"
ex5.c:#include <1j.h>
The "ex?.c" at the beginning of each makes each line unique, so uniq -d
can't
process. Also the \s+ in your egrep command can't match ^#include ...
Thanks anyway: I know I could strip out the ex?.c, but this still
doesn't
get me what I want...
