Package: zsh Version: 4.3.11-4 Severity: normal It seems that if you unset the SHLVL environment variable, the SHLVL is not properly propagated over exec:
% zsh % echo $SHLVL 2 % unset SHLVL % echo $SHLVL % perl -e 'print "$ENV{SHLVL}\n"' % exec perl -e 'print "$ENV{SHLVL}\n"' 1 The last line is unexpeced. In bash, it is 0. zsh must be caching SHLVL for some special handling during exec; but the cache is not updated by unset. If you set SHLVL explicitly, things are as expected (at least this is the same as bash): % zsh % SHLVL=9 % echo $SHLVL 9 % perl -e 'print "$ENV{SHLVL}\n"' 9 % exec perl -e 'print "$ENV{SHLVL}\n"' 8 Andrew -- System Information: Debian Release: wheezy/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: i386 (i686) Kernel: Linux 2.6.38-2-686 (SMP w/1 CPU core) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages zsh depends on: ii libc6 2.11.2-11 Embedded GNU C Library: Shared lib ii libcap2 1:2.20-1 support for getting/setting POSIX. ii libncursesw5 5.9-1 shared libraries for terminal hand Versions of packages zsh recommends: ii libc6 2.11.2-11 Embedded GNU C Library: Shared lib ii libpcre3 8.12-3 Perl 5 Compatible Regular Expressi Versions of packages zsh suggests: ii zsh-doc 4.3.11-4 zsh documentation - info/HTML form -- debconf information: zsh/rcmove: -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
