DESCRIPTION
===========
- ifquery can be used to parse interface configuration file, dump
+ **ifquery** can be used to parse interface configuration file, query
running state or check running state of the interface with configuration
- in /etc/network/interfaces file.

- ifquery always works on the current interfaces(5) file
- /etc/network/interfaces.

OPTIONS
=======
positional arguments:
- IFACE interface list separated by spaces. IFACE list and '-a' argument are mutually exclusive.
+
+ **IFACE** interface list separated by spaces. **IFACE** list and **'-a'** argument are mutually exclusive.
optional arguments:
+
-h, --help show this help message and exit
-a, --all process all interfaces marked "auto"
-d, --debug output debug info
- --allow CLASS ignore non-"allow-CLASS" interfaces
+ -l, --allow CLASS ignore non-"allow-CLASS" interfaces
- --with-depends run with all dependent interfaces. This option
+ -w, --with-depends run with all dependent interfaces. This option
is redundant when -a is specified. When '-a' is
specified, interfaces are always executed in
dependency order.

1 on error
- --print-dependency {list,dot} print iface dependency in list or dot format.
+ -p, --print-dependency {list,dot} print iface dependency in list or dot format
- --syntax-help print supported interface config syntax. Scans all
+ -s, --syntax-help print supported interface config syntax. Scans all
addon modules and dumps supported syntax from them

DESCRIPTION
===========
- reloads network interfaces(5) file /etc/network/interfaces.
+ reloads network **interfaces(5)** file **/etc/network/interfaces**.
runs ifdown on interfaces that changed in the interfaces file and
subsequently runs ifup on all interfaces.
- ifreload is equivalent to ``ifdown -a`` followed by ``ifup -a``
+ ifreload is equivalent to **ifdown -a** followed by **ifup -a**
but it skips ifdown for interfaces that did not change in the config
file.
EXAMPLES
========
- # reload /etc/network/interfaces file
- ifreload -a
+ # reload all auto interfaces in **interfaces(5)** file
+
+ **ifreload -a**
# reload all interfaces using service command
- service networking reload
