So I have this makefile rule :

header:
 rm -f ./include/temp.txt
 cat ./srcs/ft_*/ft_*.c | grep -E "^w" | sed 's/$$/;/' | sed '/int main/d' | sed '/inttmain' >> ./include/temp.txt
 awk '//; /# define/while(getline<"header.h")print' temp.txt >tmp
 mv tmp header.h

I am trying to create a lib project and I have a lot of functions in the ./srcs/ directory, each functions is stored in a ft_name_of_the_function directory. I want to have a Makefile rule that edit the header file of the lib (which is in ./include/ and called header.h) by adding each prototype.

This script was working as a shell executable but doesn't seem to work after I put this in the makefile. I can still tell the makefile to run a shell executable but I would like to understand. When I run make header it gives me this standard output :

rm -f ./include/temp.txt
cat ./srcs/ft_*/ft_*.c | grep -E "^w" | sed 's/$/;/' | sed '/int main/d' | sed '/inttmain' >> ./include/temp.txt
sed: -e expression n°1, caractère 10: expression régulière d'adresse inachevée
Makefile:41: recipe for target 'header' failed
make: *** [header] Error 1

This sed command:

sed '/inttmain'

is not formed properly. You need an optional address (or addresses) and an action. If you run this at the command line you get this:

$ sed '/inttmain'
sed: -e expression #1, char 10: unterminated address regex

If you want it to be like the previous one:

sed '/int main/d'

but with a tab instead of a space, you probably want this:

sed '/inttmain/d'

You can combine these by using s+ to match some whitespace:

sed '/ints+main/d'

I just figure out I did some other mistakes so in some case people are trying to do the same thing here is my final code :

cp ./include/initlibft.h ./include/libft.h
rm -f ./include/temp.txt
cat ./srcs/ft_*/ft_*.c | grep -E "^w" | sed 's/$/;/' | sed '/main(/d' >> ./include/temp.txt
awk '//; /# define/while(getline<"./include/temp.txt")print' ./include/libft.h >tmp
mv tmp ./include/libft.h
