Method: Dir#chdir

Defined in:

dir.c

#chdir ⇒ 0 #chdir { ... } ⇒ Object

Changes the current working directory to self:

Dir.pwd # => "/"

With a block, temporarily changes the working directory:

• Calls the block.

• Changes to the given directory.

• Executes the block (yields no args).

• Restores the previous working directory.

• Returns the block’s return value.

Uses Dir.fchdir if available, and Dir.chdir if not, see those methods for caveats.

Overloads:

• #chdir ⇒ 0

  Returns:

  • (0)
• #chdir { ... } ⇒ Object

  Yields:

  Returns:

  • (Object)
