I tried to extract the attached zstandard-compressed tar archive `testdir.tar.zst' using the dired-guess-default suggested shell command, which is unzstd -c %i | tar -xf - It fails with the message zstd: can't stat %i : No such file or directory -- ignored tar: This does not look like a tar archive tar: testdir.tar.zst: Not found in archive What instead works is using the command tar --use-compress-program=unzstd -xvf My GNU tar version also is able to automatically detect zstandard files, so basically just "tar -xvf" is suffisient, but the version with "--use-compress-program=unzstd" is backwards-compatible to older tar versions. I suggest fixing that in `dired-guess-shell-alist-default'. Though there might be tar versions out there which don't support `--use-compress-program' (I don't know), then maybe a piping solution might be better, but that should be done in a way that avoid the above error (not sure what actually causes it). I use GNU tar version 1.35 and unzstd version v1.5.5. --- In GNU Emacs 29.1 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.38, cairo version 1.17.8) System Description: Arch Linux Configured using: 'configure --with-pgtk --with-native-compilation=aot --sysconfdir=/etc --prefix=/usr --libexecdir=/usr/lib --with-tree-sitter --localstatedir=/var --with-cairo --disable-build-details --with-harfbuzz --with-libsystemd --with-modules 'CFLAGS=-march=x86-64 -mtune=generic -O2 -pipe -fno-plt -fexceptions -Wp,-D_FORTIFY_SOURCE=2 -Wformat -Werror=format-security -fstack-clash-protection -fcf-protection -g -ffile-prefix-map=/build/emacs/src=/usr/src/debug/emacs -flto=auto' 'LDFLAGS=-Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now -flto=auto' 'CXXFLAGS=-march=x86-64 -mtune=generic -O2 -pipe -fno-plt -fexceptions -Wp,-D_FORTIFY_SOURCE=2 -Wformat -Werror=format-security -fstack-clash-protection -fcf-protection -Wp,-D_GLIBCXX_ASSERTIONS -g -ffile-prefix-map=/build/emacs/src=/usr/src/debug/emacs -flto=auto'' Configured features: ACL CAIRO DBUS FREETYPE GIF GLIB GMP GNUTLS GPM GSETTINGS HARFBUZZ JPEG JSON LCMS2 LIBOTF LIBSYSTEMD LIBXML2 MODULES NATIVE_COMP NOTIFY INOTIFY PDUMPER PGTK PNG RSVG SECCOMP SOUND SQLITE3 THREADS TIFF TOOLKIT_SCROLL_BARS TREE_SITTER WEBP XIM GTK3 ZLIB Important settings: value of $LC_COLLATE: C.UTF-8 value of $LC_CTYPE: en_GB.UTF-8 value of $LC_MESSAGES: en_US.UTF-8 value of $LC_MONETARY: de_DE.UTF-8 value of $LC_NUMERIC: en_US.UTF-8 value of $LC_TIME: de_DE.UTF-8 value of $LANG: C value of $XMODIFIERS: \@im=fcitx locale-coding-system: utf-8-unix Major mode: Dired by name Minor modes in effect: shell-dirtrack-mode: t tooltip-mode: t global-eldoc-mode: t show-paren-mode: t electric-indent-mode: t mouse-wheel-mode: t tool-bar-mode: t menu-bar-mode: t file-name-shadow-mode: t global-font-lock-mode: t font-lock-mode: t blink-cursor-mode: t buffer-read-only: t line-number-mode: t indent-tabs-mode: t transient-mark-mode: t auto-composition-mode: t auto-encryption-mode: t auto-compression-mode: t Load-path shadows: None found.
