How to execute a long CURL command on zsh on mac terminal? - macos

Trying to run a curl command on macos terminal which I was able to run from a windows command prompt. The curl command is relatively long with multiple "--data-urlencode" flags (5 total) and then the final -v flag. On windows, I can simply copy/paste the command to the command prompt or powershell, press Enter, and it runs fine. However, on macos terminal using zsh, the command prompt just shows a reverse prompt after I try to press Enter. It's as if it is waiting for more input or some other run command which I am not aware of.
On macos, I have been able to run shorter curl commands without any issues, but when I paste in a relatively longer curl command, I am presented with more prompts as if zsh doesn't realize the command input is done. I have also tried to manually type out the command to see if copy/paste is the issue, but same problem. I have also tried to change the order of the flag options, but that doesn't make any difference either. I have googled the heck out of this, but alas - no joy.

Bash script for setting up mac keeps skipping commands or simply prints to the console without executing lines

I've been trying to create a bash script that allows me to transfer my existing dev setup to a brand new macbook.
I set up a bash script which is supposed to automate this process but for some reason when I call the script using curl, it doesnt seem to reliably run the whole thing and I cant figure out why that is. example of commands being printed to the console and note executed
If I were to manually enter each line into the terminal and execute, things work as expected however doing so defeats the purpose of the script.
I'll attach some screenshots of the terminal output so you can see the exact issues I'm facing and at which point it behaves oddly.
I've had to run the script a few times to get it to execute the skipped steps but it would be good to understand why certain steps are getting missed. Here's a link to my gist containing the script. Would appreciate any suggestions for improvements or explantations for the behaviour I'm seeing.
Things I have tried that havent resolved my issue:
Splitting the script into two smaller scripts
Erasing my mac and running the script again (done this several times)
Adding sleep 5 between each command
edit: this is how I'm running the script
sudo curl -Lks https://gist.githubusercontent.com/curtis-j-campbell/b695513a44393c3a5084c011c6d0c890/raw | /bin/bash
Thanks in advance
It appears that everything after brew install git is being echoed. That suggests that something in that command is copying its stdin to stdout, so it's processing the rest of the script. Change that line to
brew install git </dev/null
so it won't read the script as its stdin.
Also, you don't need to run curl under sudo. If you need privileges to install the program, you should run bash as the superuser, not curl.
curl -Lks https://gist.githubusercontent.com/curtis-j-campbell/b695513a44393c3a5084c011c6d0c890/raw | sudo /bin/bash

Line wrapping in cygwin prompt?

I have looked at duplicate questions. Nothing has worked.
I use Gitbash, and when using Cygwin, I source the gitbash prompt (/Git/etc/bash.bashrc) to display the same prompt. In Gitbash, the prompt works. In cygwin, the output line wraps. For example:
[ "$python_version" ] && python_version='\[\033[95;38;5;227m\]🐍'"${python_version##* } "
This line causes a wrap (only in cygwin) when appended to PS1. The minttyrc and color settings are exactly the same. Removing the color, which I think is the problem, fixes the wrap. However, I believe everything is escaped correctly, and as it doesn't wrap in gitbash, I don't know what the problem is.
The color here seems to be the issue, as removing it fixes it. But why? What is so different about the terminals? I also wonder if it could be an issue with an early escape, but PyCharm's shellcheck says it's all fine.
Wrapping example:
Cygwin:
⬢14.7.0p/new 🐍3.8.3 (venv) ❯
GitBash (ideal output):
~/Desktop/new 🐍3.8.3 ⬢14.7.0 (venv) ❯
It only occurs within the prompt (PS1 variable, aka PROMPT_COMMAND); not when actually typing out commands in the terminal.
Answer: Cygwin is trash (excuse the exaggeration). It has so many utilities but many have encountered bugs like this, and it is really a shame. I uninstalled it, removed its variables from PATH, and with C:\Program Files\Git\bin added to such, I could now ssh in using ssh -t user#host bin "bash -l". This gave me a correct prompt, in ssh or not, with no wrapping; I was able to install other utilities, such as g++, using MinGW. I hope Cygwin gets things sorted out soon, as I debugged in every single way; changed no code, uninstalled it, and then had a successful output.

Preserving PS1 while in SSH with GitBash?

I have a complicated prompt. Very. I use git-bash for windows.
SSH-ing in on gitbash sends me to the CMD prompt. I know to type ssh -t user#host "bash -l" to get a bash prompt. It works, however, I use a repository called gitstatus to speed up the parsing of the git commands, and sshing in using bash -l calls the PS1 set in /c/cygwin/etc/bash.bashrc (for Mintty), NOT ~/bash.bashrc (for GitBash). This initially seems fine, as I can just copy paste the code from the GitBash *.bashrc to cygwin's. However, the gitstatus repository only works on bash terminals, aka not Cygwin/Mintty, so the prompt when I ssh in appears quite slower in git repos (Mintty doesn't allow gitstatus to be sourced and speed up parsing, once again) than if I was not SSH-ed in and using the GitBash-sourced prompt.
Are there any work arounds for this? I have seen many simnilar questions here but none have provided me a solution.
If you're in my situation, just source the scripts (duh). If you can't execute foo in file x when it should do the same thing as bar in file y, just source bar from file x. It seems obvious but took me a moment.
ALSO: Make sure to run dos2unix.exe on admin command prompt to remove carriage returns every time you make a change.

Print terminal command output directly into vim - macOS

Whenever I enter a terminal command in vim (e.g., !echo hello), I am momentarily kicked out to view the result of that terminal command and then prompted with Press ENTER or type command to continue. This is a bit jarring. I would like to stay within vim and with the command output printed out at the bottom.
I know vim :read will take the terminal output and actually put it into my buffer, but that is not what I am looking to do. Here is some reading if you are interested in a tangent.
It looks like when I run vim in Screen I get what I am looking for, but I am trying to get this to work with tmux and the stock Mac terminal.
After a ton of research, probably too much, I got it! It looks like vim will send commands to the terminal, which in turn defines the behavior of how the terminal commands are processed from vim. Put this into your .vimrc file:
set t_ti= t_te= " show results from terminal commands within vim!
From what I understand, this just makes sure to send nothing to the terminal, which yields my desired results!
Side note: the above addition to your .vimrc file will also prevent the vim buffer from clearing when exiting vim (e.g., :wq). I am okay with this! It is kind of nice sometimes to see what you were just working on :).

cd into folders breaks/hangs zsh for minutes using Windows cmd, Powershell, Hyper, and Bash (Ubuntu)

To clarify which I've tried:
Ubuntu bash
Hyper
Powershell
Git bash
cmd
I have installed Ubuntu bash on my Windows 10 PC. When I open ubuntu.exe up and I type zsh after the shell has started, my zsh shell starts up instead, as expected. This is perfectly fine and it does exactly what I want.
The problem: When I do the following sequences:
cd
[TAB]
[ARROW KEYS] (select an item)
ENTER
It should cd into that folder. And it does that, but it literally takes over a minute to do so. CTRL+C to cancel does not work.
Now that I'm in that folder, I can clear the console by typing clear, so that's what I do:
user#user-pc > /mnt/c/folder/otherfolder > GIT-REPO > clear
When I type clear and hit enter, it takes probably 30+ seconds before it clears the window.
I have tried a bunch of themes and a bunch of terminals/command prompts, but none of them work, not even the default one.
I've installed zsh and oh-my-zsh by doing these commands inside the Ubuntu bash shell:
sudo apt-get install zsh
curl -L https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh | bash
Any idea why this odd behavior happens? It looks like it's zsh, because I can easily cd into other folders using all of the above terminals. The problem also happens if I simply cd /mnt/c/folder/otherfolder/ with and without the trailing slash.
Does it only happen in that particular folder? IME, large git repositories can be really slow on zsh+WSL even with the default prompt.
