Why does zsh not work in an Emacs shell mode any more?

Z-Shell Frequently-Asked Questions
Emacs 19.29 or thereabouts stopped using a terminal type of "emacs" in shell buffers, and instead sets it to "dumb". Zsh only kicks in its special I'm-inside-emacs initialization when the terminal type is "emacs". Probably the most reliable way of dealing with this is to look for the environment variable $EMACS, which is set to t in Emacs' shell mode. Putting [[ $EMACS = t ]] && unsetopt zle in your .zshrc should be sufficient.

Why does zsh kill off all my background jobs when I logout?

Z-Shell Frequently-Asked Questions
Simple answer: you haven't asked it not to. Zsh (unlike [t]csh) gives you the option of having background jobs killed or not: the nohup option exists if you don't want them killed. Note that you can always run programs with nohup in front of the pipeline whether or not the option is set, which will prevent that job from being killed on logout. (nohup is actually an external command.

How does synchronization mode work?

DenyHosts Frequently Asked Questions
DenyHosts daemons periodically connect (based on the configuration file parameter SYNC_INTERVAL) to the denyhosts.net remote server. If hosts have been denied by this daemon then they will automatically be transmitted to denyhosts.net. If new hosts have been denied by others (that is, other users running DenyHosts in synchronization mode), then they will be added to your HOSTS_DENY file automatically (based on your SYNC_DOWNLOAD_THRESHOLD setting).

Why does shell mode lose track of the shell's current directory?

GNU Emacs FAQ
Emacs has no way of knowing when the shell actually changes its directory. This is an intrinsic limitation of Unix. So it tries to guess by recognizing 'cd' commands. If you type cd followed by a directory name with a variable reference (cd $HOME/bin) or with a shell metacharacter (cd ../lib*), Emacs will fail to correctly guess the shell's new current directory.

How does incremental mode work?

AspectJ Frequently Asked Questions
In incremental mode, ajc minimizes the files that need to be recompiled after another file has changed. In Java, only the changed files need to be recompiled, but in AspectJ, other files might also need to be recompiled or re-woven. Depending on what is modified, we may need to re-weave code. If you change a pointcut and save it, we currently have to check everywhere in case a new match is occurring or an old match is no longer correct.

I don't have root access: how do I make zsh my login shell?

Z-Shell Frequently-Asked Questions
Unfortunately, on many machines you can't use chsh to change your shell unless the name of the shell is contained in /etc/shells, so if you have your own copy of zsh you need some sleight-of-hand to use it when you log on. (Simply typing zsh is not really a solution since you still have your original login shell waiting for when you exit.) The basic idea is to use exec <zsh-path> to replace the current shell with zsh. Often you can do this in a login file such as .

How do I use a shell in Emacs?

GNU Emacs FAQ for Windows
You can use an interactive subshell in Emacs by typing "M-x shell". Emacs uses the SHELL configuration variable to determine which program to use as the shell. If you installed Emacs using the addpm.exe program, then addpm.exe will associate the value %COMSPEC% with SHELL in the registry. Emacs will then use the value of the COMSPEC environment variable when it starts up, unless the SHELL environment variable is explicitly defined (as when using the emacs.bat batch file).

Why does value mode not work for date conditions?

LIM Frequently Asked Questions
Many people have tried to mix value mode with date conditions. For example, take the query SHOW 1: DJIA WHEN Date is 1 value after yearly Close What people are trying to do with this is to get the first value of 'DJIA' after the close of the year. I.e., the yearly close happens on 12/31; a day later is 1/1 which is a New Year's Day, a holiday. So, people expect the query to return the value of 'DJIA' on the day immediately after New Year's Day. Unfortunately, that is not how the system works.

Subject: 7.35 How come my alt key combinations don't work in emacs X mode?

It is even possible to use both Alt keys together, resulting in Meta-versions of the extra characters. For some reason, Flex licensing requires /dev/lan0 to have read and write permissions for everybody. This is somewhat insecure, but is fixed in FLEXlm versions after 2.4. You should really upgrade your software, but if you can't, pls see their Web Site (see below) or here is one workaround: chgrp/chmod g+s on any binaries that need to access /dev/lan0.

A4.4 Is there an Emacs mode for Gri?

Gri Frequently Asked Questions
Yes. Peter Galbraith has written a very powerful mode for Gri commandfiles which is supplied with Gri and which is fully documented in the manual. The capabilities of the mode include the following. Uses built-in knowledge of Gri commands to 'complete' your commands. For example, typing 'drM-TAB' (where M-TAB is the completion keystroke) causes the mode to write 'draw' in place of the 'dr'. Pressing M-TAB again gives a list of all Gri commands starting with 'draw'.

What is a dual-mode tag and how does it work?

ARS Tracking Assets at the Speed of Business
Most RFID devices are single mode of operation devices. This means that they operate at a specific frequency for both transmitting and receiving data (or commands). Almost all passive devices are single mode. For instance operation at 13.56 MHz or 868/915 MHz means that the devices are commanded at this frequency and modulate a return signal at the same frequency. Semi-active devices are generally single frequency devices but use a battery to boost signals.
