Package: screen Version: 4.0.3-0.3 Severity: normal
This is likely to bite people who do semi-advanced scripting involving screen. Consider this example script: #!/bin/sh [ $STY ] || exit 1 sleep 5 screen -t one sh -c "sleep 5; ping -c20 localhost | tee /tmp/1" echo $? sleep 1 screen -t two sh -c "sleep 10; ping -c20 localhost | tee /tmp/2" echo $? If I run it inside an attached screen, it does the obvious: creates two temporary windows after 5s, and run ping inside them. But if I detach before the 5s have passed, neither window is created and ping is not run. Both screen invocations still exit successfully. I have no idea if there is a good reason for this behavior. If there is, I can't see it. The screen FAQ doesn't mention what should happen, but everything else works so insanely well with detached screens, so this comes as a complete surprise. It's not Debian-specific because I see it on RedHat Enterprise Linux 4 too ... but it is easier to report it in a well-known and open place like Debian's BTS than to RH or the screen mail address. -- System Information: Debian Release: 4.0 APT prefers stable APT policy: (500, 'stable') Architecture: powerpc (ppc) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.18-3-powerpc Locale: LANG=sv_SE, LC_CTYPE=sv_SE (charmap=ISO-8859-1) Versions of packages screen depends on: ii base-passwd 3.5.11 Debian base system master password ii debconf [debconf-2.0] 1.5.11etch1 Debian configuration management sy ii libc6 2.3.6.ds1-13etch4 GNU C Library: Shared libraries ii libncursesw5 5.5-5 Shared libraries for terminal hand ii libpam0g 0.79-5 Pluggable Authentication Modules l ii passwd 1:4.0.18.1-7 change and administer password and screen recommends no packages. -- debconf information: screen/old_upgrade_prompt: false -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
