data_type: string

tool: D7: Usage: mygrep PATTERN [OPTION]... [FILE]...
Search for PATTERN in each FILE or standard input.
PATTERN is, by default, a basic regular expression (BRE).
Example: mygrep -i 'hello world' menu.h main.c



tool: D11: -i, --ignore-case         ignore case distinctions
	while matching the pattern ignore the difference between capital and small letters.
-r, --recursive           like --directories=recurse
	if combine '-r' with '*' search pattern recursivly in all files of the current directory
	if only use '-r' then search in all directories.
-A, --after-context=NUM   print NUM lines of trailing context
-c, --count               print only a count of matching lines per FILE
-L, --files-without-match  print output with line numbar
