- 对我的启动脚本的某些修改以
dash: 1: [[: not found结尾，并以ashshell结束。 - 我自然地认为这是一些基于配置文件（.profile等）的脚本，该脚本在基于POSIX的shell上运行时使用了
bash的{{1}}。但是不知道是哪一个。 - 因此决定在
[[下运行它，以查找正在读取的所有文件。结果令我惊讶-strace输出中未列出任何基于配置文件的文件。
结果
strace使用普通$ strace -fe trace=%file bash -c exit

运行，这样似乎也什么也没显示。
问题
- 如何列出外壳程序最终读取的所有文件？ （请注意，问题不是根据文档应该读取的内容，而是真正在运行时读取的 内容）
- 为什么上面没有显示
strace -f bash |& grep profile，.profile，/etc/profile/etc/bashrc等中的任何一个？ - （有点偏离主题）为什么在这里发生一系列
.bashrc-ENOENT-似乎是在所有env路径上搜索bash。但是为什么会这样呢？ （如何在此处找到实际执行stat("/home/quarkstone/.cargo/bin/bash",0x7ffe62a61e90) = -1 ENOENT (No such file or directory)命令的内容，从而导致PATH搜索）
