Bash Version: 4.2
Patch Level: 24
Release Status: release
Description:
Executing `cd //` will put you in the root directory as expected;
however executing `pwd` will report "//" as your working directory.
Also, if your Bash prompt has "$PWD" in it then it will also
report "//" as your working directory. This quirk appears only
with the Bash builtin version of `pwd`; the GNU Coreutil version of
`/bin/pwd` will report "/" as expected.
Also note that if you execute `cd ///` or `cd ////` or `cd /////`, etc...
then you will be put in the root directory and `pwd` will report "/"
as expected. In other words, this quirk appears only if you cd to "//".
Repeat-By:
#!/bin/bash
cd /
pwd
/usr/bin/pwd
cd //
pwd
/usr/bin/pwd
cd ///
pwd
/usr/bin/pwd
cd ////
pwd
