My embedded system have a industrial computer,the industrial PC run a program automatically while it boot,because I had add a command line in the rc.local,the program can display its status in realtime.I can telnet to the industrial PC with root user,now is the question:How can I watch the program's stdout in the industiral PC ,or redirection the process stdout?

Thank you for any suggestion!

tee takes stdout and redirects it wherever and also sends it to the original stdout.

Code:

mything tee somefile

will write to both the somefile file and to stdout.

Thank you for your tip,the tee command can redirection the stdout to a file and stdout,but I want to redirection the stdout of a process which is running,I can get the process ID by " ps -al",I don't want to stop and restart the process,I just want to see the process stdout.
