정답:
usrsharezoneinfo
Explanation:
The /usr/share/zoneinfo directory contains the binary time zone files that are used by the system to determine the local time for any region. The files are organized in subdirectories by continent, country, or ocean. Some files represent the standard time zones, while others may have historical or political variations. To set the system's timezone, one can create a symbolic link from /etc/localtime to the appropriate file in the /usr/share/zoneinfo directory. For example, to set the timezone to America/New_York, one can use the command sudo ln -sf /usr/share/zoneinfo/America/New_York /etc/localtime. Alternatively, one can use the timedatectl command to set the timezone without creating the link manually. Reference:

정답:
etstatbinnetstatssusrbinss
Explanation:
The netstat command, meaning network statistics, is a command-line utility in the Linux system to display network configuration and activity, including network connections, routing tables, interface statistics, masquerade connections, and multicast memberships1. The netstat command can display different types of network data depending on the command line option selected. Some of the common options are:
-a: This option displays active TCP connections, TCP connections with the listening state, as well as UDP ports that are being listened to.
-r: This option displays the routing table information, which is a list of rules that determine where the packets are sent.
-i: This option displays the network interface information, such as the name, MTU, RX-OK, TX-OK, etc.
-s: This option displays the network statistics by protocol, such as TCP, UDP, ICMP, IP, etc.
For example, to display the open network connections, one can run:
netstat -a
To display the routing table, one can run:
netstat -r
To display the network interface statistics, one can run:
netstat -i
To display the network statistics by protocol, one can run:
netstat -s
