Enhance the cd command in cmd
Add some new features to the cd command: * `cd`: go to %HOME% or %USERPROFILE% * `cd -`: go to previous directory * `h`: show 10 lines of history * `cd [0-9]`: go to the history lines passed in parameter * `p`: pop the last line in the history, and go there (sort of undo cd) Also, no need to pass the `/d` parameter anymore, cd will change the drive automatically.

|
||||
|
||||
If you want to run SSH agent on startup, uncomment the line in `/vendor/init.bat`so it says `@call "%CMDER_ROOT%/bin/agent.cmd"`.

|
||||
### cd new feature
|
||||
|
||||
The `cd` command has some new usefull features:
|
||||
* `cd`: go to `%HOME%` or `%USERPROFILE%`
|
||||
* `cd -`: go to previous directory
|
||||
* `h`: show 10 lines of history
|
||||
* `cd [0-9]`: go to the history lines passed in parameter (only if the directory does not exist)
|
||||
* `p`: pop the last line in the history, and go there (sort of undo cd)
|
||||
|
||||
Also, no need to pass the `/d` parameter anymore, `cd` will change the
|
||||
drive automatically.
|
||||
|
||||
## Todo
|
||||
|
||||
1. Complete PowerShell compatibility.
