Bash Version: 4.3
Patch Level: 11
Release Status: release
Description:
Why does bash clear OLDPWD when a child script is started?
OLDPWD is exported and passed to any children, but bash apparently clears
OLDPWD whenever a child script is started: Can bash be fixed to preserve the
value of any OLDPWD in its initial environment, like it does with PWD?
This appears to happen on all 3.x and 4.x versions of bash.
Repeat-By:
$ cd /etc
$ cd
$ perl -e 'print "<$ENV{OLDPWD}>\n"'
</etc>
$ ksh -c 'echo "<$OLDPWD>"'
</etc>
$ bash -c 'echo "<$OLDPWD>"'
