UNIX Humour

[Bakul Shah]

Don't you mean:

cat > hello.c <<EOF
#if 0 /* Magic self-executing C source code.  Run "hello.c"
gcc -Wall -O $0 -o ${0%%.c}
${0%%.c}
rm ${0%%.c}
exit 0

*/
#endif

#include <stdio.h>
int main(void)
{
     printf ("Hi there!\n");
     return 0;
}
EOF
chmod +x hello.c
hello.c
Hi There!
