提问by Mark Szymanski
Is there any way to get the SSID of the current wireless network through a shell script on Mac OS X?
有什么办法可以通过 Mac OS X 上的 shell 脚本获取当前无线网络的 SSID？

The command
命令
/System/Library/PrivateFrameworks/Apple80211.framework/Resources/airport -I
will give you details about your current wireless network connection.
将为您提供有关当前无线网络连接的详细信息。
To get specifically the SSID, use this command:
要具体获取 SSID，请使用以下命令：
/System/Library/PrivateFrameworks/Apple80211.framework/Resources/airport -I | awk -F: '/ SSID/{print }'

Where isn'tthere a wheel in need of re-inventing?
哪里没有需要重新发明的轮子？
networksetup -getairportnetwork en1 | cut -c 25-
is what you'd use on 10.6, 10.7 changed the "Hardware Port" name from "Airport" to "Wi-Fi", and therefore you'd cut off one less letter,
是您在 10.6 上使用的，10.7 将“硬件端口”名称从“机场”更改为“Wi-Fi”，因此您少了一个字母，
aru$ networksetup -getairportnetwork en1 | cut -c 24-

In case the device is named something other than en1, one needs to first get the correct device name, than the corresponding SSID:
如果设备的名称不是en1，则需要首先获得正确的设备名称，而不是相应的 SSID：
networksetup -listallhardwareports | awk '/Wi-Fi/{getline; print }' | xargs networksetup -getairportnetwork

The following has been tested on OS X and prints the SSID without any hard-coded column widths:
以下已在 OS X 上进行测试，并在没有任何硬编码列宽的情况下打印 SSID：
system_profiler SPAirPortDataType | awk -F':' '/Current Network Information:/ {
getline
sub(/^ */, "")
sub(/:$/, "")
print
}'
Essentially, this takes the output of system_profiler SPAirPortDataType, and prints the line after "Current Network Information:" trimming leading whitespace and the trailing colon (since SSIDs can contain :s).
本质上，这需要输出system_profiler SPAirPortDataType, 并在Current Network Information:修剪前导空格和尾随冒号后打印“ ”行（因为 SSID 可以包含:s）。
