Package: bash Version: 4.4-4 Severity: important Dear Maintainer,
Man page for bash seems to suggest that any interactive invocations can be identified simply by checking "$-" for 'i' or testing for the presence of a non-empty PS1 variable e.g: - "[[ -v PS1 ]]" - "[[ -n $PS1 ]]" - "! [[ -z $PS1 ]]" All of these tests used to work on my system, but no longer (I suspect something changed in the last couple of weeks). The only reliable measure I can use now to see if a script was invoked interactively is to test for "-t 0" or similar. I'm not sure if this change in behaviour is wanted or not, but if so then perhaps an update to the man and info pages should be made? Also not sure if this limited to Debian or a general issue with bash, but I've come across this on machines running jessie and stretch. -- System Information: Debian Release: 9.0 APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-1-amd64 (SMP w/2 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages bash depends on: ii base-files 9.8 ii dash 0.5.8-2.4 ii debianutils 4.8.1 ii libc6 2.24-9 ii libtinfo5 6.0+20161126-1 Versions of packages bash recommends: ii bash-completion 1:2.1-4.3 Versions of packages bash suggests: pn bash-doc <none> -- no debconf information
