6. Getting file informationΒΆ
The info command provides a visual summary of the data within any of the data files CIS supports.
To get this summary, run a command of the format:
$ cis info <datagroup> [--type ["VD" | "SD"]]
where:
<datagroup>
is a CIS datagroup specifying the variables and files to read and is of the format
[<variable>...:]<filename>[:product=<productname>]
where:variable
is an optional variable or list of variables to use.filenames
is a mandatory file or list of files to read from.product
is an optional CIS data product to use (see Data Products):
Note that the product can only be specified if a variable is specified. See Datagroups for a more detailed explanation of datagroups.
--type
allows the user to list only SD
or VD
variables from an HDF file, the default is All
Running without a variable ($ cis info <filenames>
) will print a list of the variables available in those files
such as:
Trop
latitude
longitude_1
surface
unspecified_1
level6
ht
msl
latitude_1
To get more specific information about one or more variables in those files, simply pass those as well:
$ cis info var1,var2:<filenames>
where $var1
and $var2
are the names of the variables to get the information for.
