Usage: cd [OPTIONS] [--help]
|
|
|
|
Move into new context (object or scope). As in UNIX shells use `cd ..` to go
|
|
back, `cd /` to return to Pry top-level and `cd -` to toggle between last two
|
|
scopes. Complex syntax (e.g `cd ../@x/@y`) also supported.
|
|
|
|
cd @x
|
|
cd ..
|
|
cd /
|
|
cd -
