+Usage: md5sum [OPTION]... [FILE]...
+Print or check MD5 (128-bit) checksums.
+With no FILE, or when FILE is -, read standard input.
+
+  -b, --binary            read in binary mode
+  -c, --check             read MD5 sums from the FILEs and check them
+  -t, --text              read in text mode (default)
+  Note: There is no difference between binary and text mode option on GNU system.
+
+The following three options are useful only when verifying checksums:
+      --quiet             don't print OK for each successfully verified file
+      --status            don't output anything, status code shows success
+  -w, --warn              warn about improperly formatted checksum lines
+
+      --help     display this help and exit
+      --version  stampa le informazioni sulla versione ed esce
+
+The sums are computed as described in RFC 1321.  When checking, the input
+should be a former output of this program.  The default mode is to print
+a line with checksum, a character indicating type (`*' for binary, ` ' for
+text), and name for each FILE.
