试图找到一种在更改目录后在BASH中执行功能的方法.

Trying to find a way to execute a function within BASH after changing into a directory.

例如，

# cd code/project/blah "Your latest modified files are main.cc blah.hpp blah.cc" (~/code/project/blah) # _

通过上述内容，我希望能够将其他功能包装在bash命令周围.

With the above I'm hoping to be able to wrap other functionality around the bash command.

希望通过zsh钩子函数找到一些东西 zsh.sourceforge/Doc/Release/Functions.html#SEC45

Was hoping to find something along the lines of zsh hook functions zsh.sourceforge/Doc/Release/Functions.html#SEC45

推荐答案

不要忘记 pushd 和 popd ，除非您从不使用它们.我会这样做:

Don't forget about pushd and popd, unless you never use them. I'd do this:

PS1='(\w) \$ ' chdir() { local action="$1"; shift case "$action" in # popd needs special care not to pass empty string instead of no args popd) [[ $# -eq 0 ]] && builtin popd || builtin popd "$*" ;; cd|pushd) builtin $action "$*" ;; *) return ;; esac # now do stuff in the new pwd echo Your last 3 modified files: ls -t | head -n 3 } alias cd='chdir cd' alias pushd='chdir pushd' alias popd='chdir popd'
