" "If the argument HEX is given, the binary data will be converted to " "hexadecimal representation and this will be stored in the variable.\n" "MD5, SHA1, SHA224, SHA256, SHA384, and SHA512 " "will compute a cryptographic hash of the content of a file.\n" "STRINGS will parse a list of ASCII strings from a file and " "store it in a variable.
