我已经在双启动中安装了 Parrot OS，一切正常。当我检查互联网连接时，它没有显示任何适配器。我有一台带 Wi-Fi 适配器的 MacBook Air：BCM4355 802.11ac 无线。另一个问题是我没有以太网端口，所以如果我必须安装任何软件包，我必须从 USB 上安装。有人知道如何使适配器工作吗？谢谢！
我查看了一些论坛，但它们不适用于 Parrot OS 或 Debian。我试图检查是否有适用于我的 4355 的驱动程序，但没有找到。
如何在 Mac 上获取现代 coreutils？
我遇到了这个问题使用csplit：
foo.txt:
foo
1
foo
2
foo
3
$: csplit foo '^foo$' '{*}'
# error
仔细检查manpage, man csplit,csplit在 Mac 上是 FreeBSD 版本并且不提供该'{*}'选项。事实上，我必须提前提供确切的拆分次数。这将触发czplit我重新实施，或者我可以GNU coreutils在 mac 上使用。
有办法吗？
如何在macos中将HTTP_PROXY大写定义为http_proxy小写？
有没有办法将 HTTP_PROXY 设置为与 http_proxy 类似的工作？
GNU sed新手来了...
我有几个 FASTA 文件（50K），标题格式为
CYTC2889-12|Homo sapiens
我想用下划线得到
CYTC2889-12|Homo_sapiens
并将结果写入文件。
我在 macOS 上运行
我试过了
sed -i.bak 's/\s/_/g' file.fas
但这给了
>CYTC2889-12|Homo _apien_
这很接近，但不正确
有什么想法吗？
July 2022 mac os Monterey V12.1
awk --version 20200816
GNU bash, version 3.2.57(1)-release (x86_64-apple-darwin21)
为什么awk -F对大多数字母有效，但对字母无效t？我有解决方案，但我想了解为什么 awk 对 letter 失败t。
# Count 'e's
% echo "tweeter" | awk -F "e" '{print NF-1}'
3
# Count 'r's
% echo "tweeter" | awk -F "r" '{print NF-1}'
1
# (Attempt to) count 't's
% echo "tweeter" | awk -F "t" '{print NF-1}'
0 <=== ????
# Use gsub()
% echo "tweeter" | awk '{print gsub(/t/, "")}'

我的网络活动显示我正在下载大量未显示在活动监视器中的数据。有没有我可以使用的程序实际上有效？
我试过launchctl list了，但我不知道之后该怎么做。
我也尝试过ps -ax |more，但无法弄清楚任何事情。
我尝试编辑 /private/etc/hosts 和设置

但它什么也没做
我还打开了防火墙并将其设置为阻止所有传入连接。还是没有变化。9GB d/led 现在还在增加。
我也试过看，nettop但我不知道其中哪些在做 d/ling。有关 nettop 的输出，请参见下图。
物品从 NETTOP 中消失是否正常？我看到某些条目出现了半秒钟，然后消失了。

您如何仅获得硬件接口
试过：
ifconfig -a
ip link show
如何使用 ifconfig/ip link show 仅获取本地硬件接口？
就像从我的 ifconfig 我得到（删除了很多）：
en0: inet 192.168.0.146 netmask 0xffffff00 broadcast 192.168.0.255
utun0:
utun1:
utun2:
utun3:
utun4:
更新：我猜这是以前软件接口连接的接口。
然后我用 lsof 对接口 utun 进行了调查：
sudo lsof | grep utun
identitys 577
identitys 577
identitys 577
identitys 577
identitys 577
好吧identitys，在我找到 nmap 工具之前，我仍然认为它是我的计算机本地的东西：
sudo nmap -sn 192.168.0.127/24
Nmap scan report for 192.168.0.6
Host is up (0.13s latency).
MAC Address: <xx:xx:xx:xx:xx:xx> (Sonos)
... # And more
原来是我在本地 Wifi 网络上的 Sonos 扬声器。
为什么 ipconfig/if link show 显示其他接口？
谢谢
我正在运行 macOS 12.3.1
我在我的 .zshrc 中添加了几行，即。
export GREP_OPTIONS='--color=always'
export GREP_COLOR='1;35;40'
在此之后，当我将 grep 输出通过管道传输到 tr 时，它返回相同数量的行，但所有行都是空白的
例如：
grep ^.....$ /usr/share/dict/words | tr "[:lower:]" "[:upper:]"
返回 10230 个空行。
这是预期的吗？
我正在尝试执行以下操作：
echo "/Users/anon/Applications/Chrome Apps.localized/Spotify.app" |
sed -E 's:([^\/]*$).*:\1:'
我认为它会捕获Spotify.app并用它替换整个字符串，但这不起作用。相反，我得到了整个字符串。
所以，我想也许我的正则表达式是错误的，所以我做了下面的测试：
echo "/Users/anon/Applications/Chrome Apps.localized/Spotify.app" |
sed 's:[^\/]*$:PWA.app:'
但我得到了预期的输出：/Users/anon/Applications/Chrome Apps.localized/PWA.app.
所以，我不确定我在这里做错了什么。为什么分组时相同的正则表达式不匹配？
