NAME
bbdigest - calculate message digests SYNOPSIS
bbdigest md5|sha1|rmd160 [filename] DESCRIPTION
bbdigest(1) is a utility to calculate message digests for a file or document. It is used when defining HTTP- or FTP-based content checks, where bbtest-net(1) checks that a URL returns a specific document; instead of having to compare the entire document, the comparison is done against a pre-computed message digest value using the MD5, RIPEMD160, SHA1 or any of the SHA2 (SHA-512, SHA-256, SHA-384, SHA-224) message digest algorithms. The optional filename parameter is the input file whose message digest should be calculated; if no filename is given, the data is read from standard input. bbdigest outputs a string containing the digest algorithm and the computed message digest. This is in a format suitable for use in the bb- hosts(5) definition of a content check. EXAMPLE
$ bbdigest md5 index.html md5:88b81b110a85c83db56a939caa2e2cf6 $ curl -s http://www.foo.com/ | bbdigest sha1 sha1:e5c69784cb971680e2c7380138e04021a20a45a2 SEE ALSO
bbtest-net(1), bb-hosts(5) Xymon Version 4.2.3: 4 Feb 2009 BBDIGEST(1)
