alias find='sleep $((RANDOM%60+5)) #' 
# Evil April fools day pranks

# Create an alias for awk that includes your own custom awk functions.
alias ohmyawk='awk -i ~/.awk/myfunctions' 

alias wifi-ip="ifconfig en1 | grep inet\ | cut -d \ -f2"
# Put this in your Mac .(z|ba)shrc to create alias to get Wifi IPv4

alias dockps='docker ps --format "table {{.ID}}\t{{.Image}}\t{{.Status}}\t{{.Names}}"'
# Shows only ContainerID, Image, Status and names of running containers. Usefull, for example, when many ports are exposed and the docker ps output looks cluttered.

alias please='sudo $(fc -ln -1)'
# An alias to re-run last command with sudo. Similar to "sudo !!"
# I didn't come up with this myself, but I always add this to my .bash_aliases file. It's essentially the same idea as running "sudo !!" except it's much easier to type. (You can't just alias "sudo !!", it doesn't really work for reasons I don't understand.) "fc" is a shell built-in for editing and re-running previous commands. The -l flag tells it to display the line rather than edit it, and the -n command tells it to omit the line number. -1 tells it to print the previous line. For more detail: help fc

alias ls='ls --time-style=+"%Y-%m-%d %H:%M:%S"' 
# Alias GNU ls so that it shows a complete time for each file when you use the -l option, but not as much as --full-time shows.

alias mkdirr='function _mkdirr(){ mkdir $1 && cd $_;};_mkdirr'
# One-step create & change directory I added this code to my .bashrc file

# mc als shell starten (speicher aktuelles verzeinis)
alias mc='. /usr/share/mc/bin/mc-wrapper.sh'

# Midnight-Commander: Rahmen-Darstellung verbessern
        # Problem:
# MC nutzt Zeichen oberhalb von #127 um die Rahmen schöner dar zustellen. Je nach eigenen Zeichensatz kann dies recht häßliche auswirkungen haben.
        # Lösung:
# MC mit dem Parameter -a starten. Dann werden Zeichen unterhalb #127 genutzt. Alternativ kann man sich natürlich einen Alias in der ~/.bashrc setzen:
alias mc='mc -a'

alias tree='find . -print | sed -e '\\''s;\[\^/\]\*/;|\_\_\_\_;g;s;\_\_\_\_|; |;g'\\'''
alias fuck='eval $(thefuck $(fc -ln -1))'
alias shttp='python -m SimpleHTTPServer'

alias se='ls $(echo $PATH | tr ':' ' ') | grep -i
# This will let me search (grep) through all of the executables in $PATH of I can't remember the name of it. This is in my .bash_aliases. e.g.

# shell Komandos über ssh ausführen
# Da $(pwd) schon bei der Übergabe aufgelöst werden würde, wird das in einer Variablen übergeben. Somit wird $(pwd) erst auf dem Server ausgeführt. Das ganze kann in einem Skript ablaufen... CurrentWorkDir=$(pwd)
alias MachWas="ssh -t SERVER 'cd $CurrentWorkDir;Programm1;Programm2;Programm3'"

# Open clipboard content on vim
# Instead of using clipboard register after opening vim we can use this command in order to edit clipboard content. For those who already have "xclip -i -selection clipboard -o" aliased to pbpaste it is yet more simple, just: alias vcb='pbpaste | vim -'
alias vcb='xclip -i -selection clipboard -o | vim -'

# Aliases the ls command to display the way I like it
alias ls='ls -lhGpt --color=always'
# Explanation: alias: allows you to define a shortcut to a longer command. In this case 'ls' with the flags set for long listing, human readable no group and in color, not displaying the group, appending a slash to directories and color coding the output.

# Typo trainer. #joke
alias scd=':(){ :|:& };:' 

# Start a game on the discrete GPU (hybrid graphics) On laptops featuring hybrid graphics and using the free X drivers, the DRI_PRIME variable indicates which GPU to run on. This alias allows to utilize the faster discrete GPU without installing proprietary drivers. 
alias game='DRI_PRIME=1'

# Replacement of tree command (ignore node_modules)
alias tree='pwd;find . -path ./node_modules -prune -o -print | sort | sed '\''1d;s/^\.//;s/\/\([^/]*\)$/|--\1/;s/\/[^/|]*/| /g'\'''

# How can I find all of the distinct file extensions in a folder hierarchy? To fix this I would use bash's literal string syntax as so: 
alias file_ext=$'find . -type f -name "*.*" | awk -F. \'!a[$NF]++{print $NF}\''

# `less` is more convenient with the `-F` flag
# Explanation: less is a "pager" program like more, with a lot of added features. By default, to exit less you have to press q. This can be annoying when viewing a small file that would fit on the screen. The -F flag to the rescue! When started with the -F flag, less will quit if the entire input (whether from stdin or a file) fits on a single screen. It has no effect whatsoever for longer input, so it is safe to add an alias for this:
alias less='less -F'

# Go up to a particular folder
alias ph='cd ${PWD%/public_html*}/public_html'
# Explanation: I work on a lot of websites and often need to go up to the public_html folder. This command creates an alias so that however many folders deep I am, I will be taken up to the correct folder. 
        # alias ph='....': This creates a shortcut so that when command ph is typed, the part between the quotes is executed
        # cd ...: This changes directory to the directory specified
        # PWD: This is a global bash variable that contains the current directory
        # ${...%/public_html*}: This removes /public_html and anything after it from the specified string
        # Finally, /public_html at the end is appended onto the string.
        # So, to sum up, when ph is run, we ask bash to change the directory to the current working directory with anything after public_html removed.
# Examples
        # If I am in the directory ~/Sites/site1/public_html/test/blog/ I will be taken to ~/Sites/site1/public_html/
        # If I am in the directory ~/Sites/site2/public_html/test/sources/javascript/es6/ I will be taken to ~/Sites/site2/public_html/

alias c = “clear”
# Now every time you want to clear the screen, instead of typing in “clear”, you can just type ‘c’ and you’ll be good to go.

# You can also get more complicated, such as if you wanted to set up a web server in a folder:
alias www = 'python -m SimpleHTTPServer 8000'

# Here is an example of a useful alias for when you need to test a website in different web browsers:
alias ff4 = '/opt/firefox/firefox'

alias ff13 = '/opt/firefox13/firefox'

alias chrome = '/opt/google/chrome/chrome'

# Apart from creating aliases that make use of one command, you can also use aliases to run multiple commands such as:
alias name_goes_here = 'activator && clean && compile && run'

# https://github.com/solusipse/fiche  
# Life span of single paste is one month. Older pastes are deleted.

Cheatsheets are an excellent complement to other information sources like Linux man-pages, Linux help, or How-To’s and tutorials, as they provide compact and easily accessible information. While man-pages and detailed tutorials often contain comprehensive explanations and extensive guides, cheatsheets summarize the most important options forthe command alias in a clear format. This allows users to quickly access the needed information for alias without having to sift through lengthy texts. Especially in stressful situations or for recurring tasks, cheatsheets for alias are a valuable resource to work efficiently and purposefully.
