type: command not found

I have a problem with my code because I do not know why if I debug it well because when I run it, it gives me the following errors.

I can not understand if it is a problem of some include, because it has execution permissions -x I call it from ./consumidor.c and the debugging with gcc consumidor.c -or consumidor.

Thank you very much in advance I hope someone can help me maybe it's silly but I can not find the solution
