atuin:tldr:a3916
This command is using the eval
command in combination with command substitution ($(atuin init ${select})
).
The eval
command in bash is used to evaluate and execute the given arguments as a shell command. It takes the arguments, concatenates them into a single command, and then executes that command.
The command substitution part, $(atuin init ${select})
, is enclosed within $()
which means that the output of the command inside the parentheses is substituted in place. So, the command atuin init ${select}
is executed, and its output is used as part of the evaluated command.
To break it down further:
${select}
is a variable being passed as an argument to theatuin init
command.atuin
is likely the name of a program or script that is being called.init
is an argument being passed to theatuin
command to execute some initialization process.
Overall, this command executes the atuin
command with the init
argument, passed with the value of the ${select}
variable, and then evaluates the resulting command.
