One Day One GNU/Linux Command ============================= sha1sum - Compute & Check Secure Hash Algorithm Std 1 message digest. Summary: `sha1sum' computes a 160-bit checksum/fingerprint/message-digest for each specified file. `sha1sum' can also determine whether a file & checksum are consistent. The sums are computed as per the FIPS-180-1 [http://www.itl.nist.gov/fipspubs/fip180-1.htm]. Example: $ sha1sum file -- Compute and print the MD5 checksum of that file. $ sha1sum -c input.txt -- Read checksum and filename from the file and validate checksums. $ sha1sum -w -c input.txt -- Same as above and warn if the checksums format is wrong in the file. $ sha1sum --status -c input.txt -- Indicate the status in exit status code. Read: man sha1sum input.txt Format:- 2bff10a7855964335a86e84efb5f4ce9c40d4cfd file1 e62341664decd9f55896ab3635697de29ed1077f file2 9b088ddc22456233a76 file3 HTH :) -- Bharathi S _______________________________________________ To unsubscribe, email [EMAIL PROTECTED] with "unsubscribe <password> <address>" in the subject or body of the message. http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
