22 amanda-match \- Common Amanda Match Expression
25 Several Amanda commands allow the user to specify dumps using "match expressions"\&. This manual page describes the syntax of these expressions\&.
27 In some places, only certain match expressions are allowed\&. However, several commands take a dump specification ("dumpspec") consisting of a sequence of several expressions intended to match particular dumps in the catalog\&. Other applications take a DLE specification which indicates a set of DLEs to be operated on\&. These formats are described below\&.
28 .SH "HOST & DISK EXPRESSIONS"
30 The hosts and disks match by word\&. Each word is a glob expression, and words are separated by the character \'\&.\' for host expressions and \'/\' for disk expressions\&. You can anchor the expression on the left with a \'^\' or on the right with a \'$\'\&. The matcher is case insensitive for hosts but case sensitive for disks\&. A match succeeds if all words in the expression match contiguous words in the host or disk\&.
32 If the disk is a UNC ("\e\ewindows\eshare") then all \'\e\' are converted to \'/\' before the match\&. Using \'\e\' is complicated because of the extra quoting required by the shell and amanda\&. It\'s easier to use \'/\' because it requires less quoting ("//windows/share")
34 The special characters follow\&. Note that the shell interprets some of these characters, so when used on the command line, they must be escaped appropriately for the shell\&.
38 word separator for a host
43 word separator for a disk
48 word separator for a UNC disk
53 anchor at left of word
58 anchor at right of word
63 match exactly one character except the separator
68 match zero or more characters except the separator
73 match zero or more characters including the separator
78 match exactly one of the characters enclosed by the brackets\&.
83 match exactly one character that is not enclosed by the brackets\&.
91 foo\&.hosta\&.org, and
156 (note dots:) \&.opt\&.
192 \e\ewindows2\eshare\&.
200 \e\ewindows\eshare2\&.
206 \e\ewindows\eshare\&.
208 .SH "DATESTAMP EXPRESSIONS"
210 A datestamp expression is either a prefix of the datestamp, or a range expression (separated by \'\-\') matching several prefixes\&. A leading ^ is removed, while arailing $ will force an exact match\&.
215 match all dates beginning with 20001212, 20001213 or 20001214
225 match all dates between 20001212 and 20001224
230 match all dates that start with 2000121 (20001210\-20001219)
235 match all dates that start with 2 (20000101\-29991231)
240 match all dates between 20000101\-20101231
247 .SH "LEVEL EXPRESSIONS"
249 Level expressions are either prefix matches e\&.g\&., "1", which matches "1", "10", and "123", absolute matches e\&.g\&., "3$" which only matches "3", or a range e\&.g\&., "3\-5" which only matches levels 3, 4, and 5\&.
250 .SH "DUMP SPECIFICATIONS"
252 A dump specification is used to select one or more dumps from the catalog\&. It consists of a sequence of match expressions in the order host, disk, datestamp, and level\&. Note that some commands do not take a level argument, out of historical accident\&. Note, too, that the datestamp expression matches the time that the dump was made on the Amanda client, rather than the date it was moved to tape\&.
255 amtool MyConfig ^vpdesktop$
257 all dumps of host "vpdesktop"
260 amtool MyConfig \'*\' /var/stage
267 amtool MyConfig www1 /var/www \'*\' www2 /var/www \'*\'
269 All dumps of /var/www on www1 and www2 (assuming amtool does not require a level argument)
271 .SH "DLE SPECIFICATIONS"
273 A DLE specification is used to select one or more DLEs\&. It consists of a sequence of match expressions\&. The first must be a host, and subsequent expressions will be experimentally matched against both hosts and disks in the
274 \fBdisklist\fR(5), preferring hosts\&. This dynamic matching process can lead to odd behavior in extreme cases (e\&.g\&., where a disk and a host have the same name), but for most uses does exactly what is expected\&.
277 amtool MyConfig vpdesktop /home/anderson
283 amtool MyConfig \'*\' ^/etc \'*\' ^/var
292 amtool MyConfig web1 www web2 www
294 If no host matches "www", all DLEs matching
296 on hosts web1 and web2\&. If a host matches "www", then all DLEs on hosts www, web1, and web2\&.
