How to compile

By default multitail requires the ncursesw library (ncursesW!) to compile and run. You can choose to use the non-wide char version (ncurses) by setting UTF8_SUPPORT to "no" in the makefile. Note that this disables UTF8 support. On Cygwin, you need the libpcre-devel package.

Tips

Following Python tqdm / HuggingFace Trainer logs that use carriage-return progress bars? Start MultiTail with --collapse-cr so lone \r overwrites are collapsed instead of forming multi-hundred-KB lines:

multitail --collapse-cr train.log

You can also use MultiTail to view logfiles on other hosts! How? Like this: multitail -l "ssh username@host tail -f file" Q: but then I cannot enter the password! A1: use authentication via keys A2: or use "ssh-agent": then you only once have to enter your passphrase (so login once to that host manually, and then start MultiTail)

Q & A

Q: the program fails then resizing the terminal-window A: solution: upgrade ncursesw to version 5.3 (or more recent)

Q: when I use the -l option on some program, I get nothing in the window A: now that is strange! please tell me what program you're trying to interface to MultiTail. please do: any help is appreciated!
