1 # if 0
2 echo "Hello from bash!"
3 exit
4 # endif
5 # include
6 # include
7 int main (int argc, char* argv []) {
8 puts ("Hello from C!")
9 return EXIT_SUCCESS
10}
Next, let me see if I use such a program:
1$ sh test.sh.c
2 Hello from bash!
3$ gcc test.sh.c-o test
4 $. / test
5 Hello from C!
You can even make a source code that compiles and runs itself. As follows:
1 # if 0
2 file= `mktemp`
3 gcc-o $file $0
4$ file
5 rm $file
6 exit
7 # endif
8 # include
9 # include
ten
11 int main (int argc, char * argv []) {
12 puts ("Hello from C!")
13 return EXIT_SUCCESS
14}
Run:
1$ sh test.sh.c
2 Hello from C!
