Bash - pushd

1 - About

Adds a directory to the top of the directory stack, or rotates the stack, making the new top of the stack the current working directory.

If the pushd command is successful, a dirs is performed as well.

3 - Syntax

3.1 - With no arguments


pushd 

With no arguments, exchanges the top two directories and returns 0, unless the directory stack is empty.

3.2 - First Form


pushd [-n] [dir]

if supplied, have the following meanings:

  • -n: Rotates the stack so that the nth directory (counting from the right of the list shown by dirs, starting with zero) is at the top.
  • or ?? -n Suppresses the normal change of directory when adding directories to the stack, so that only the stack is manipulated.
  • dir Adds dir to the directory stack at the top, making it the new current working directory.

pushd returns 0 unless the cd to dir fails.

3.3 - Second Form


pushd [-n] [+n] [-n]

where:

  • +n: Rotates the stack so that the nth directory (counting from the left of the list shown by dirs, starting with zero) is at the top.
  • -n: Rotates the stack so that the nth directory (counting from the right of the list shown by dirs, starting with zero) is at the top.
  • -n Suppresses the normal change of directory when adding directories to the stack, so that only the stack is manipulated.

pushd returns 0 unless the directory stack is empty, a non-existent directory stack element is specified, or the directory change to the specified new current directory fails.

4 - Example

4.1 - Go away and returns


# we are now in /
pushd /aDir/
# we are now in /aDir/
popd
# we are now back in the starting current directory /
