The command grex -d ${space_separated_strings} is using the grex tool with the -d flag and passing a variable ${space_separated_strings} as an argument.

grex is a command-line tool that generates regular expressions (regex) based on input strings. It helps in creating regex patterns by analyzing the given input strings. It is a useful tool for quickly constructing regex patterns.
The -d flag in this command specifies that the input strings are space-separated or delimited by spaces.
${space_separated_strings} is a placeholder for a variable that should be replaced with actual space-separated strings. This variable should be provided when running the command. It can contain one or more strings separated by spaces.

So, when you run this command with the appropriate value for ${space_separated_strings}, grex will analyze the provided strings and generate a regular expression pattern that matches all given strings.
