strings - extract printable strings

Strings  finds  and prints strings containing 6 or more consecutive printable UTF-encoded characters in a
       (typically) binary file, default standard input.  Printable characters are taken to be  ASCII  characters
       from blank through tilde (hexadecimal 20 through 7E), inclusive, and all other characters from value 00A0
       to  FFFF.   Strings reports the decimal offset within the file at which the string starts and the text of
       the string. If the string is longer than 70 runes the line is terminated by three dots and  the  printing
       is resumed on the next line with the offset of the continuation line.
