autocomplete - zsh cdpath and autocompletion


My CDPATH in zsh looks like this:


export CDPATH='.:..:../..'

Unfortunately, this means that when I try to autocomplete after typing 'cd ', there're way too many irrelevant autocomplete options, depending on where I am. For example, if I'm in my home directory, typing cd tries to autocomplete every user on the system because CDPATH has ".."


Is there a way to keep my CDPATH as shown above, but have the autocomplete for cd, pushd, etc. ignore the CDPATH value, and autocomplete only based on the current directory?



Answer



path-directories


One way is to add the following completion settings in your .zshrc to remove path-directories from the suggestion sources.


zstyle ':completion:*:complete:(cd|pushd):*' tag-order \
    'local-directories named-directories'

group names


Alternatively or additionally, the following settings should display a heading for all respective groups of completion suggestions so you can see which directories are local directories and which are suggestions from your cdpath.


zstyle ':completion:*' group-name ''
zstyle ':completion:*:descriptions' format %d

You can apply standard prompt formats to these descriptions to make them stand out:


zstyle ':completion:*:descriptions' format %B%d%b        # bold
# zstyle ':completion:*:descriptions' format %S%d%s        # invert/standout
# zstyle ':completion:*:descriptions' format %U%d%u        # underline
# zstyle ':completion:*:descriptions' format %F{green}%d%f # green foreground
# zstyle ':completion:*:descriptions' format %K{blue}%d%k  # blue background
# etc.

That helps make sense of the different sources quite a bit in my experience.



Note 1: zsh has two representations for array variables like PATH and CDPATH, of which the lower case variant is an actual array. This means you can:


cdpath=(path/to/dir /path/to/another/dir)

Or, to get your desired result:


cdpath=(.. ../..)

I personally find it a bit more readable than the colon-separated pseudo array.


Note 2: Exporting CDPATH isn't necessary unless you have several programs that want it set.

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...

linux - Extract/save a mail attachment using bash

Using normal bash tools (ie, built-ins or commonly-available command-line tools), is it possible, and how to extract/save attachments on emails? For example, say I have a nightly report which arrives via email but is a zip archive of several log files. I want to save all those zips into a backup directory. How would I accomplish that? Answer If you're aiming for portability, beware that there are several different versions of mail(1) and mailx(1) . There's a POSIX mailx command, but with very few requirements. And none of the implementations I have seem to parse attachments anyway. You might have the mpack package . Its munpack command saves all parts of a MIME message into separate files, then all you have to do is save the interesting parts and clean up the rest. There's also metamail . An equivalent of munpack is metamail -wy .

performance - Single Threaded Qaud Core v.s Hyper-Threading Dual Core

Let's say we have two CPUs, One is Quad Core 3.2 Ghz with 4 Cores, and We have a Dual Core 3.2 Ghz with 2 Cores with 2 threads in each Core (Hyper-Threading). My assumption as a programmer will be, the 4 cores 4 threads should perform faster than 2 cores 4 threads since the second CPU needs to switch between threads in order to emulate 4 cores while the first one doesn't need to perform such switching as each core can perform independently and individually. I want to confirm that my assumption is true, if not please explain why one is better than the other. Answer I do believe thats true - since hyper threading does share some elements - specifically the main execution resources, you'll be able to run 4 full threads at once, rather than waiting for those resources to be freed up. The point of HT is to get better performance with a smaller use of die area - your quad core would generally be a bigger chip - say almost twice as large, than a non HT dual core chip, while a HT...

freeze - How do I stop windows 8.1 from freezing when the screen locks

This happens to me on a regular basis if I leave the computer for upwards of 10 minutes. It didnt do so at first but started after a couple of days. This is possibly related to further windows updates although nothing seems to tie in obviously when looking at my update history. I have to hold the power button in to power off. If the screens have switched off aswell they wont come back on, if they haven't I see the login picture and can move the mouse pointer but nothing happens and no combination of keyboard mashes or mouse clicks lets me see the login prompt. In the event log (type event viewer into the start menu) under system before every Critical problem (me powering down the machine without restarting) I get distributedCOM errors talking about this guid: "The server {BF6C1E47-86EC-4194-9CE5-13C15DCB2001} did not register with DCOM within the required timeout." I also get the same error for this 1B1F472E-3221-4826-97DB-2C2324D389AE. This seems to be a common theme and...
