GNU/Linux Command – MD5SUM

md5sum — Compute and Check MD5 Check sums.
`md5sum’ computes a 128-bit checksum/fingerprint/message-digest for each specified file. `md5sum’ can also determine whether a file and checksum are consistent.
$ md5sum file -- Compute and print the MD5 checksum of that file.  $ md5sum -c input.txt -- Read checksum and filename from the file and validate checksums.  $ md5sum -w -c input.txt -- Same as above and warn if the checksums format is wrong in the file.  $ md5sum --status -c input.txt -- Indicate the status in exit status code.  Format of input.txt file: 787e64182f251c0b877f734cbe77d987 file1 be7b28e15963d38e05591118cfe049d2 file2 9b088ddc22456233a76 file3
