The first line of my ~/.profile is ENV=$HOME/.shinit export ENV. My environment always works, I don’t have to learn fish or any other syntax. profile a number of different times for a number of different shells, I came up with a way to decouple my environment config from the shell I use.

Where Fish Shell Contains own Aliases (functions) Files. Which works for me, because I have no interest in learning fish syntax. Because it's a function in fish you can't expand the body in the command line as you type the alias. I also have a few quick aliases for working on the command line in general.One of the things I like about fish is how there are sane defaults and I don’t need to have any config. In fish the alias command just creates a trivial function. This implementation detail typically has the side effect that any state. The last alias just adds defaults to the ping command. Subshells are child programs that run a few commands for the shell and then exit. It’s a good example of using more complex operations like querying data from a website or API. The third alias is a quick and dirty way of showing the public IP address of the host (or whatever router etc., is fronting the Internet in your network). You could easily do the same on Linux by specifying the correct interface instead of en0 and tweaking the cut command. The second alias is MacOS specific and returns the current IP address of your host. You could do a similar thing with netstat or ss, but this version works on both Linux and macOS. The first alias, ports, uses the lsof command to show every listening UDP and TCP port on the host. 1 I have a bash script and I want to use a command in it, that I defined in my config. You can type:Īlias ports = "sudo lsof -i -n | egrep 'COMMAND|LISTEN|UDP|TCP'" alias mip = "ifconfig en0 | grep inet | grep -v inet6 | cut -d ' ' -f2" alias myip = "curl echo" alias ping = "ping -c 5" Other built-in commands include cd to change directories or echo to write output. You can think about running a built-in command like typing inside a file in your editor and a sub-process as opening a new file. Built-ins are commands that can be run inside the currently running shell process, rather than fork-ed and exec as a sub-process. Aliases and built-in commandsĪliases are created using the alias built-in command. ![]() To find more aliases, you can check folks’ dotfiles repositories on Github as a starting point.

Note that at the moment universal variables are stored in a file whose name is unique to each host. For example, lets create an alias called ll which will expand to ls -l. This allows you to create a shorthand name for a longer command, including its default arguments. The aliases in this post will work for both Bash, which is broadly the default shell on most Linux distributions and zsh, which is the default shell on macOS. 1 Answer Sorted by: 12 Some settings, such as the color theme, are stored as universal variables.
