grex

$ grex -i ${space_separated_strings}

try on your machine

The command "grex -i ${space_separated_strings}" is using the "grex" tool with the "-i" option and a variable called "space_separated_strings".

Here's the breakdown of each component:

"grex": "grex" is a command-line tool used to generate regular expressions (regex) by analyzing input strings. It helps create pattern matching rules for text processing.
"-i": The "-i" option is used to make the command case-insensitive. This means that the generated regex will match both uppercase and lowercase versions of the input strings.
"${space_separated_strings}": This is a variable that stores space-separated strings. The variable's value could be set elsewhere in the script or environment. It represents a collection of strings that the "grex" command will analyze to create the regex.

Overall, the command uses the "grex" tool to analyze the given space-separated strings, generates a regular expression pattern, and outputs it. The generated regex pattern can then be used for various purposes, such as searching, matching, or extracting specific text patterns from other text files or data sources.
