Hello I am trying to fix a problem with the return value coming from exit within a if statement. This test shows the problem: barebox:/ cat ./tif if [ 1 -ne 0 ]; then echo in if exit 1 fi barebox:/ ./tif in if barebox:/ echo $? 0 In common/hush.c run_list_real(struct pipe *pi) calls run_pipe_real(struct pipe *pi). In function run_pipe_real(struct pipe *pi) line 540 a child pipe is started. This child pipe works fine and set a prober last_return_code. After return from run_list_real(struct pipe *pi) the return value -2 (Line 702) is given from run_pipe_real(struct pipe *pi) to run_list_real(struct pipe *pi) and here the right last_return_code will be overwritten. exit is a command only modifying the wanted exit value r with "return -r - 2". So here we have also -2 or -3 as return value. Is the problem located in the line 700 "if (rcode < -1)" statement, or should exit be a reserved word to controls the flags? I am not sure why we need the father pipe. Kind Regards Dipl. Ing.
