atach is a session manager for dtach.
If all you need is detachment and attachment functionality, screen is
overkill. Unfortunately, using dtach requires manual management of socket
files. Let atach manage dtach sessions (sockets) for you instead.
atach [‐option ...] [session | [command [arguments ...]]
How do I create a new session?
atach pianobar
How do I reattach to a detached session?
atach pianobar
What if I want the session name to be different from the command name?
atach -s radio pianobar
How do I list sessions?
atach
How do I delete a ghost session from a rare dirty dtach exit?
atach -L | grep pianobar | xargs rm
Is there more?
atach --help
homebrew/atach.rb is a Homebrew formula to be installed in $(brew --prefix)/Library/Formula.
compleat/atach.usage is a Compleat completion file to be installed in ~/.compleat.
zsh/_atach is a Zsh completion file to be installed
somewhere in $FPATH.
What if once in a blue moon, I need multiple windows, should I just revert to
screen or tmux? No, there is a much simpler alternative, but more on that
later. First, a few words on screen and tmux.
GNU Screen has not been updated for a couple of years and others are reluctant to adopt it since it has twisted spaghetti code that will make an Italian chef cringe. It is riddled with bugs and the configuration file syntax is attrocious. Most result to googling for other's dot files to copy/paste. However, it does have the advantage of being installed everywhere.
TMUX is the new kid on the block, has
great potential, and is installed by default on a few BSD derivatives. Though,
a few years old, it is still quite buggy, especially on Mac OS X. For example,
pbpaste, used to paste the contents of the clipboard to stdin, does not
work. The patch to make pbpaste work will will result in fatal:
dispatch_imsg: imsg_read failed when executing tmux attach-session, which
defeats the purpose of using tmux if one cannot reattach. It can also randomly
freeze and fail to exit when the subprocess exits. There are also problems with
RPROMPT in ZSH being malformed and the cursor being misplaced.
The UNIX philosophy is 'Write
programs that do one thing and do it well.', also known as, 'Keep it simple,
stupid!' dvtm (Dynamic Virtual
Terminal Manager) is a tiling window manager similar to X11 window managers for
the console. Using atach with dvtm is simple. One does not have to worry
about configuration files, in fact, there are none, nor does one have to worry
about the TERM environmental variable and how to get tput colors to output
256. It just works.
atach -s evil-project dvtm
