Some variables, like $PWD, only have one value. In fact, all variables in fish are really lists, that can contain any number of values, or none at all. If it had been two arguments, then name would have been a list of length 2. The set command above used quotes to ensure that Mister Noodle was one argument. This is how fish usually receives the values for things like $LANG, $PATH and $TERM, without you having to specify them again.Įxported variables can be local or global or universal - “exported” is not a scope! Usually you’d make them global via set -gx MyVariable SomeValue.įor more, see Exporting variables. And whatever started your terminal emulator also gave it some variables that it will then pass on unless it specifically decides not to. So if your terminal emulator starts fish, and it exports $LANG set to en_US.UTF-8, fish will receive that setting. This works the other way around as well! If fish is started by something else, it inherits that parents exported variables. It can also be unexported with -unexport or -u. > set -x MyVariable SomeValue > env | grep MyVariable MyVariable=SomeValue Running Commands ¶įish runs commands like other shells: you type a command, followed by its arguments.

If you have a strong understanding of other shells, and want to know what fish does differently, search for the magic phrase unlike other shells, which is used to call out important differences.

This, however, is not a very user-friendly approach.Īn easier way to avoid this error is to add the executable files’ directory to the PATH variable. One way to overcome this error is to write the complete directory of the executable file (or its alias) instead of just entering the command name.
