3.4.6. vzpkg info

This command displays information about EZ templates, YUM software packages, and individual software packages.

Syntax.  

vzpkg info [-F {<OS_template>|<CT_name>} -q|-d <app_template> [<parameters> ...]
vzpkg info -p|-g [-C|-r] [-F {<OS_template>|<CT_name>} -q|-d {<package_name>|<yum_package_group>} [<parameters> [...]]

Table 3.29. Options

NameDescription

<CT_name>

Container name.

<OS_template>

OS EZ template.

<app_template>

Application EZ template.

<package_name>

Software package name.

<yum_package_group>

YUM software group name.

-F, --for-os {<OS_template>|<CT_name>_}

Displays information on the application EZ template or the software package (if the -p option is specified) included in the specified OS EZ template or applied to the indicated container.

-p, --package

Displays information about the specified software package. Must be used with the -F option.

-g, --groups

Displays information about the packages included in the specified YUM software group.

-C, --cache

Displays the information on the specified package from the local vzpkg cache. You can omit this parameter if the elapsed time from the last vzpkg cache update does not exceed the value of the METADATA_EXPIRE parameter specified in the /etc/vztt/vztt.conf file.

-r, --remote

If the elapsed time from the last vzpkg cache update does not exceed the value of the METADATA_EXPIRE parameter specified in the /etc/vztt/vztt.conf file, you should use this option to make vzpkg info get the information on the specified package from the remote repositories set for handling the EZ template where this package is included.

-d, --debug <num>

Sets the debugging level to one of the specified values (from 0 to 10). 10 is the highest debug level and 0 sets the debug level to its minimal value.

-q, --quiet

Disables logging to the screen and to the log file.

While executed, vzpkg info parses the subdirectories and files located in the /vz/template/<os_name>/<os_version>/<arch>/config directory and containing the EZ template meta data. To run the command, you should specify either the OS EZ template or the container name. In either case, detailed information on the corresponding OS EZ template is displayed. You can also use the -F option to get the necessary information on any application EZ template included into the OS EZ template or applied to the container.

By default, vzpkg info displays all meta data on the EZ template/package specified. However, you can reduce the amount of the output information by using special parameters (<parameters>) listed in the table below.
