Package: file Version: 5.11-2 Severity: normal Dear Maintainer,
In some cases, 'file' misreports an explicitly declared '#!/bin/sh' POSIX shell script as 'data'. My best guess is that these large files contain self-extracting binary payload which is being found by 'file', but they are most certainly still shell scripts and IMHO, an explicit '#!' (shebang, magic interpreter) line should NEVER be overriden by any analysis algorithm in 'file', unless it is to provide more details. (and this is new behaviour in 'wheezy') (i.e. it seems that some new algorithm has been given higher precedent than simply reporting the shebang interpreter contents) $ lsb_release -ds Debian GNU/Linux 7.0 (wheezy) $ file --version file-5.11 magic file from /home/sdowdy/.magic:/usr/share/file/magic $ cat /home/sdowdy/.magic cat: /home/sdowdy/.magic: No such file or directory (i.e. no user overrides, and i haven't touched /usr/share/file/magic*) (any of Dell's DUP .BIN kits exhibit this issue, so i provide one as an example) $ wget http://downloads.dell.com/FOLDER00797936M/1/R710_BIOS_VCNMH_LN32_6.3.0.BIN ... 2013-05-06 14:31:23 (1.16 MB/s) - `R710_BIOS_VCNMH_LN32_6.3.0.BIN' saved [5103874/5103874] $ file R710_BIOS_VCNMH_LN32_6.3.0.BIN R710_BIOS_VCNMH_LN32_6.3.0.BIN: data (on 'squeeze', this is not misreported as data, but correctly as POSIX shell script) [squeeze:begin] pick:tmp# lsb_release -ds Debian GNU/Linux 6.0.6 (squeeze) pick:tmp# wget http://downloads.dell.com/FOLDER00797936M/1/R710_BIOS_VCNMH_LN32_6.3.0.BIN 2013-05-06 15:07:21 (1.16 MB/s) - "R710_BIOS_VCNMH_LN32_6.3.0.BIN" saved [5103874/5103874] pick:tmp# file R710_BIOS_VCNMH_LN32_6.3.0.BIN R710_BIOS_VCNMH_LN32_6.3.0.BIN: POSIX shell script text executable [squeeze:end] $ head -2 R710_BIOS_VCNMH_LN32_6.3.0.BIN #!/bin/sh $ head -10 R710_BIOS_VCNMH_LN32_6.3.0.BIN | file - /dev/stdin: POSIX shell script, ASCII text executable (correctly reported if we strip the binary payload) thanks, --stephen -- System Information: Debian Release: 7.0 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.2.0-4-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US, LC_CTYPE=en_US (charmap=ISO-8859-1) Shell: /bin/sh linked to /bin/dash Versions of packages file depends on: ii libc6 2.13-38 ii libmagic1 5.11-2 ii zlib1g 1:1.2.7.dfsg-13 file recommends no packages. file suggests no packages. -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
