Simple Unix Chat
UNIX shell is good like that, that you can combine thing in shell scripts and command-line you can make such a combined program, if you are using programs that are designed to support that (unfortunately, too many modern programs don't, although some do).However, is there a race condition with writing to the files? Since it is append mode, I would expect that would prevent other processes overwriting the file, although would it prevent other processes writing in the middle of a line if it gets interrupted? Actually, I don't know.I had made a simple two user chat system with logging using ts, tee, and nc; using a shell script with only a single line of code. This produces two log files, one for sending and one for receiving; however, I can then use cat and sort to interleave the logs into a single log file.
