# Introduction
Just a curation of commands I keep finding myself having to google.
If your often scouring through documentation or saving snippets, I would recommend using (Dash)[https://kapeli.com/dash].
## Linux
### Monitoring
Monitor the end of a file
`sudo tail -f /var/log/apache2/access.log`
### Scp
Copying from remote to local
`scp -vr user@remote:/path/to/file destination/folder`
Inverse for local to remote
`scp -vr /local/file user@remote:/path/to/destination`
_scp may not work while using zsh, so you may need to switch to bash._
## Docker
Build image (from directory where there is a dockerfile)
`docker build -t __placeholder__ .`
Create background container
`docker run -dp 9200:9200 --name ES elasticsearch`
_The "d" from -dp actually makes it run in the backfound_
Remove all images
`docker rmi -f $(docker images -q)`
Run commands inside container
`docker run -it --rm __placeholder__ bash`
Stop containers all
`docker stop $(docker ps -q)`
## Git
### Branching
Create Branch
`git branch _branch_name_`
`git checkout _branch_name_`
Shorthand for the above
`git checkout -b _branch_name_`
When happy with changes, merge
`git checkout master`
`git merge _branch_name_`
### changing config
Set global username and email
`git config --global user.name "Marc Harriss"`
`git config --global user.email [email protected]`
Get config
`git config -l`
Where to find git conf
`sublime ~/.gitconfig`
### Submodules
Pull all changes in the repo including changes in the submodules
`git pull --recurse-submodules`
Pull all changes for the submodules
`git submodule update --remote`
Add submodule and define the master branch as the one you want to track
`git submodule add -b master [URL to Git repo]`
`git submodule init`
### General
`grep -lr '<<<<<<<' . | xargs git checkout --theirs`
Copy ssh key
`cat ~/.ssh/id_rsa.pub | pbcopy .` _(mac)_
Fix host verification issue
`ssh-keyscan -H __website.com__ >> ~/.ssh/known_hosts`
### Time-machine
Remove folder once uploaded
`git rm -r --cached node_modules && touch .gitignore && echo "node_modules/" >> .gitignore`
Undo commits
`git reset --soft HEAD^`
Reset to last commit
`git reset --hard HEAD^`
## JavaScript
Listen to all events
```JavaScript
Object.keys(window).forEach(key => {
if (/^on/.test(key)) {
window.addEventListener(key.slice(2), event => {
console.log(event);
});
}
});
```
Psuedo elements
```JavaScript
var color = window.getComputedStyle(
document.querySelector('.element'), ':before'
).getPropertyValue('color')
```
## NPM
### Fix paths
`cd ~/npm-global/bin`
_Check if command your are trying to run exists_
_Add alias in ~/.zshrc | ~/.bashrc whichever terminal you use_
`alias ng="~/.npm-global/bin/__placeholder__`
### Fix npm links
Add to top of ~/.zshrc | ~/.bash_profile
`source /Users/YOUUSERNAME/.bash_profile`
View all global packages
`npm ls -g --depth 0`
Shell autocomplete
`npm completion >> ~/.bashrc`
Or
`npm completion >> ~/.zshrc`
## MacOS
Add app bar space
`defaults write com.apple.dock persistent-apps -array-add '{"tile-type"="spacer-tile";}’`
`$Killall Dock`
_repeat for each spacer_
Flush dns
`sudo killall -HUP mDNSResponder;say DNS cache has been flushed`
If that doesnt work then
`sudo killall -HUP mDNSResponder;sudo killall mDNSResponderHelper;sudo dscacheutil -flushcache;say MacOS DNS cache has been cleared`
Launching programs from the terminal.
```shell
chrome () {
open -a /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome "$1"
}
```
```shell
code () {
open -a /Applications/Visual\ Studio\ Code.app/Contents/MacOS/Electron "$1"
}
```
Watching files
`sudo fs_usage | grep my.cnf`
### Obliterate MYSQL from MAC
_Backup your databases_
Check for MySQL processes
`ps -ax | grep mysql`
Stop and kill any MySQL processes
Analyze MySQL on HomeBrew:
`brew remove mysql`
`brew cleanup`
Remove files:
`sudo rm /usr/local/mysql`
`sudo rm -rf /usr/local/var/mysql`
`sudo rm -rf /usr/local/mysql*`
`sudo rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist`
`sudo rm -rf /Library/StartupItems/MySQLCOM`
`sudo rm -rf /Library/PreferencePanes/My*`
Unload previous MySQL Auto-Login:
`launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist`
Remove previous MySQL Configuration:
`sublime /etc/hostconfig`
_Remove the line MYSQLCOM=-YES-_
Remove previous MySQL Preferences:
`rm -rf ~/Library/PreferencePanes/My*`
`sudo rm -rf /Library/Receipts/mysql*`
`sudo rm -rf /Library/Receipts/MySQL*`
`sudo rm -rf /private/var/db/receipts/*mysql*`
`sudo rm -rf /etc/my.cnf`
`sudo rm -rf /etc/mysql/`
Reboot just to ensure any MySQL processes are killed
Try to run mysql, it shouldn't work
## MongoDB
Check if apache2 active
`sudo netstat -plunt | grep apache2`
### Install and fix
`brew update`
`brew install mongodb`
`mkdir -p /data/db`
It's likely to encounter perm issues.
`sudo chown -R "id -un" /data/db`
## Browser JS
```JavaScript
Add script to head
var script = document.createElement('script');
script.src = "https://code.jquery.com/ui/1.12.1/jquery-ui.js";
script.integrity = "sha256-T0Vest3yCU7pafRw9r+settMBX6JkKN06dqBnpQ8d30=";
script.crossOrigin = "anonymous";
document.head.append(script);
```
Change icons Across Page
```JavaScript
(function (newS, selector) {
var fonts = document.querySelectorAll(selector)
fonts.forEach(function(item) {
item.classList.remove(selector);
item.classList.add(newS);
})
})('far', 'fa')
```
## Ruby
### Managing gems
```shell
gem build
gem push -
```
### Ruby gems credentials
```shell
curl -u mharriss https://rubygems.org/api/v1/api_key.yaml > ~/.gem/credentials; chmod 0600 ~/.gem/credentials
```
## Python
### Python packages
```shell
# Install latest version of setuptools and wheel
python3 -m pip install --user --upgrade setuptools wheel
# Run in the directory where setup.py is located
python3 setup.py sdist bdist_wheel
# Install Twine to upload the generated packages
python3 -m pip install --user --upgrade twine
# Upload to test.pypi.org
python3 -m twine upload --repository-url https://test.pypi.org/legacy/ dist/*
```
