The command "sensible-editor -O3 ${filename1 filename2 filename3}" specifies the use of the "sensible-editor" command with the "-O3" flag and specifies multiple filename parameters: ${filename1 filename2 filename3}.
Here's a breakdown of the command:
-
"sensible-editor": This is a command that launches the user's preferred text editor.
-
"-O3": This is a flag passed to the "sensible-editor" command. Flags are typically used to modify the behavior of a command. In this case, "-O3" could be an optimization flag that instructs the editor to use a high level of optimization when working with the provided files.
-
"${filename1 filename2 filename3}": This is a set of filename parameters enclosed in curly braces ${}. The specific filenames (e.g., "filename1", "filename2", "filename3") should be replaced with actual file names or paths when running the command. These filenames represent the files that the "sensible-editor" command should open or work with.
Overall, the command opens the user's preferred text editor with the specified optimization level and opens/works with the files provided as parameters.
