什么会创建 /tmp/fileRandomName 日志文件，如何禁用它或重定向到 /dev/null？

  • 772

每个用户登录时都会创建一些文件，这些文件/tmp看起来像.xsession-errors或其他一些日志。例如，当前名称是/tmp/filercrEUk. 我没有看到它们在注销后被删除，我也不需要它们。

    这些文件由以下人员创建/etc/X11/Xsession：

    ERRFILE=$HOME/.xsession-errors

# attempt to create an error file; abort if we cannot
if (umask 077 && touch "$ERRFILE") 2> /dev/null && [ -w "$ERRFILE" ] &&
  [ ! -L "$ERRFILE" ]; then
  chmod 600 "$ERRFILE"
elif ERRFILE=$(tempfile 2> /dev/null); then
  if ! ln -sf "$ERRFILE" "${TMPDIR:=/tmp}/xsession-$USER"; then
    message "warning: unable to symlink \"$TMPDIR/xsession-$USER\" to" \
             "\"$ERRFILE\"; look for session log/errors in" \
             "\"$TMPDIR/xsession-$USER\"."
  fi
else
  errormsg "unable to create X session log/error file; aborting."
fi

    唯一的方法是修补它。它特别包括检查 ~/.xsession-errors 是否为符号链接。我制作了一个补丁，增加了对 env var 的检查$NOXSESSIONERRORS。您可以在 中定义它/etc/environment。
