使用自定義 zshrc 啟動 zsh
我希望能夠使用類似於命令的自定義 rc 文件啟動 zsh：
bash --rc-file /path/to/file如果這是不可能的，那麼是否可以啟動 zsh，執行
source /path/to/file，然後留在同一個 zsh 會話中？注意：該命令
zsh --rcs /path/to/file不起作用，至少對我不起作用……編輯：總的來說，我希望能夠執行以下操作：
ssh到遠端伺服器“example.com”，執行zsh，source我的配置位於/path/to/file，全部在 1 個命令中。這是我一直在努力的地方，尤其是因為我不想覆蓋遠端機器上的任何配置文件。
從手冊頁：
STARTUP/SHUTDOWN FILES Commands are first read from /etc/zshenv; this cannot be overridden. Subsequent be‐ haviour is modified by the RCS and GLOBAL_RCS options; the former affects all startup files, while the second only affects global startup files (those shown here with an path starting with a /). If one of the options is unset at any point, any subsequent startup file(s) of the corresponding type will not be read. It is also possible for a file in $ZDOTDIR to re-enable GLOBAL_RCS. Both RCS and GLOBAL_RCS are set by default. Commands are then read from $ZDOTDIR/.zshenv. If the shell is a login shell, com‐ mands are read from /etc/zprofile and then $ZDOTDIR/.zprofile. Then, if the shell is interactive, commands are read from /etc/zshrc and then $ZDOTDIR/.zshrc. Finally, if the shell is a login shell, /etc/zlogin and $ZDOTDIR/.zlogin are read. When a login shell exits, the files $ZDOTDIR/.zlogout and then /etc/zlogout are read. This happens with either an explicit exit via the exit or logout commands, or an implicit exit by reading end-of-file from the terminal. However, if the shell termi‐ nates due to exec'ing another process, the logout files are not read. These are also affected by the RCS and GLOBAL_RCS options. Note also that the RCS option affects the saving of history files, i.e. if RCS is unset when the shell exits, no history file will be saved. If ZDOTDIR is unset, HOME is used instead. Files listed above as being in /etc may be in another directory, depending on the installation. As /etc/zshenv is run for all instances of zsh, it is important that it be kept as small as possible. In particular, it is a good idea to put code that does not need to be run for every single shell behind a test of the form `if [[ -o rcs ]]; then ...' so that it will not be executed when zsh is invoked with the `-f' option.因此您應該能夠將環境變數設置
ZDOTDIR為新目錄以讓 zsh 查找一組不同的點文件。正如手冊頁所建議的那樣，
RCS並且GLOBAL_RCS不是 rc 文件的路徑，因為您嘗試使用它們，而是您可以啟用或禁用的選項。因此，例如，該標誌--rcs將啟用該RCS選項，導致 zsh 從 rc 文件中讀取。您可以使用以下命令行標誌來啟用或禁用 zshRCS或GLOBAL_RCS：--globalrcs --rcs -d equivalent to --no-globalrcs -f equivalent to --no-rcs要回答您的另一個問題：
是否可以啟動 zsh，執行“source /path/to/file”，然後留在同一個 zsh 會話中？
是的，根據上述說明，這很容易。只是執行
zsh -d -f然後source /path/to/zshrc。
