何か変なことを見つけました。通常のユーザーとしてコマンドを実行すると、file常に誤ったシステムコールエラーが発生します。
例えば扱いにくい:
$ file ~/.zshrc
[1] 18553 invalid system call file ~/.zshrc
$ file ~/.bashrc
Bad system call
これはオブジェクトファイル、wm環境（ttyでも発生）に依存せず、シェルに依存しないようです。
このエラーを防ぐ唯一の方法は、コマンドをrootとして実行するか、次のコマンドを使用することですsudo。
$ sudo file ~/.bashrc
/home/user/.bashrc: ASCII text
予想される動作のようには見えません。この問題の原因が何であるかを知っている人はいますか？
デバッグを続行する方法がわかりません。このコマンドに直接関連するコンテンツが見つからなかったため、コメントやリンクが役に立ちます。fileこのコマンドの影響を受けるコマンドは1つのようです。

私はGentooを使用していますが、コンパイル時にそれを見つけました。file梱包なしseccompロゴを使えばとても良いです。

私のための1つの解決策はコンパイルすることでした。システムアプリケーション/ファイルUSE フラグを使用してパッケージを無効にします。もう1つのアプローチは、seccompUSEフラグとUSEフラグの両方を有効にしてパッケージをコンパイルすることです。seccomplzma

lzma : Support for LZMA (de)compression algorithm
seccomp : Enable seccomp (secure computing mode) to perform system call
filtering at runtime to increase security of programs
