From: Fab on 26 Jul 2010 17:20 Hello readers I use a 64-bit Linux distribution with an AMD dual core. I usually work with MATLAB in the command line. However, there is this weird thing, that when I finish the MATLAB session and return to the shell prompt (I use aterm and xterm) I can type any command but the shell does not print to stdout anymore, so I do not see what I type. I never had this problem on a 32bit machine. Does anybody know why that is, am I missing a package? Thank you Fab

Thanks Walter could you please explain what I just did or why the MATLAB session disables something in the settings? Kind regards Fab

Typically this sort of thing happens when a program takes over control of a terminal (e.g., so that it can handle in-line user editing itself) and then the program crashes before restoring the previous settings. stty echo tells the system to turn character echoing back on for the current input stream. I could refer you to the details of what stty does and how terminal input is handled in Unix, but really it wouldn't help much at all in understanding _why_ this is happening.

Anyway, thanks for your help. I've added stty echo at the end of my matlab alias and it resolves my issue like I want it to. Best, Fab |
