Re: [PLUG] pushd and popd on debian squeeze

[David Coulson <david@davidcoulson.net>]

It is an internal bash command, so you can't use 'which' or 'find' on it, as there is no binary.

yes, the script starts with #!/bin/bash

"which popd" reports nothing
"find -name popd" in the root directory shows nothing. 

It appears not to be on this box.

They're shell commands.  Make sure your script starts with:

#!/bin/bash

and NOT:

#!/bin/sh

While sh is usually symlinked to bash, if it's run as sh, it will
emulate the Bourne Shell, and bash-specific commands like pushd and
popd will not be available.
