: This is a placeholder variable that should be replaced with the desired option for selection. It could be-E
for extended regular expression or-i

: This is another variable that should be replaced with the desired value for option, based on the selected option.
"${search_pattern}"
: This variable should be replaced with the pattern you want to search for. It should be enclosed in double quotes.${filename}
