是否可以追踪我的 shell(bash, fish, zsh)？

Question

我正在使用运行ning archlinux（具体来说是 arcolinux 发行版），一切都很好，但有一个小问题让我很烦恼，这个问题是每次我打开一个终端时，这个 pops 我们在航站楼顶部

"Linux pengu 5.15.25-1-lts x86_64 未知"

我知道这是一个带有自定义标志的 uname 命令，但是我的 config.fish（我使用 fish shell（我运行 fish 和 bash i)，我知道每次我打开我的鱼 shell 我的 config.fish 运行中的东西时，我是否遗漏了什么？这是我的 config.fish:

{

fish_vi_key_bindings
set VIRTUAL_ENV_DISABLE_PROMPT "1"
set -x MANPAGER "sh -c 'col -bx | bat -l man -p'"
## Export variable need for qt-theme
if type "qtile" >> /dev/null 2>&1
   set -x QT_QPA_PLATFORMTHEME "qt5ct"
end

# Set settings for https://github.com/franciscolourenco/done
set -U __done_min_cmd_duration 10000
set -U __done_notification_urgency_level low


## Environment setup
# Apply .profile: use this to put fish compatible .profile stuff in
if test -f ~/.fish_profile
  source ~/.fish_profile
end

# Add ~/.local/bin to PATH
if test -d ~/.local/bin
    if not contains -- ~/.local/bin $PATH
        set -p PATH ~/.local/bin
    end
end

# Add depot_tools to PATH
if test -d ~/Applications/depot_tools
    if not contains -- ~/Applications/depot_tools $PATH
        set -p PATH ~/Applications/depot_tools
    end
end

set -p PATH ~/.scripts
set -p PATH /home/omar/eclipse/java-2021-12/eclipse
set -p PATH ~/bin

我试图通过在我的鱼上调用 strace 之类的东西来调试问题 shell 但它只是重新启动了我的鱼 shell，我还写了一个小脚本，我做了一个 while 循环并执行此命令：ps -ax | grep 名称；睡眠0.1 这应该给我任何 uname 命令的实例一遍又一遍地运行ning 我的鱼 shell 但没有 uname 实例我真的很困惑

Answer 1

strace 可以使用 -p:

附加到进程

-p pid         trace process with process id PID, may be repeated

这样您就可以附加到您的运行进程。

您可能还会觉得有用

  -f             follow forks
  -ff            follow forks with output into separate files

如果附加到父进程。

Answer 2

你可以通过设置fish_trace变量让fish输出它运行的命令。示例：

fish_trace=1 fish

文档中提到了这一点 around debugging fish。

Answer 3

虽然我没有跟踪鱼 shell 系统调用或类似的东西，但我意识到我正在使用 oh-my-fish 插件或框架，并且它正在加载一个显示不需要的消息的主题，感谢您的提示，虽然我至少现在知道如何追踪鱼 shell
