Sets custom environment variables before the shell starts. Was usefull as a workaround to get TERM=xterm-color inject when using terminator on ubuntu.

inject-env.c

#include <unistd.h>
#include <stdlib.h>
 
int main(int argc, char **argv) {
	char* shell = getenv("SHELL");
 
	if( shell == NULL )
		shell = "bash";
 
	char* param[2];
	param[0] = shell;
	param[1] = NULL;
 
	int i = 0;
	for( i=0; i<argc; i++ ) {
		putenv(argv[i]);
	}
 
	execvp(shell, param);
	return 0;
}
