Ubuntu `系统搜索`另一个驱动器

与其他发行版相比，我喜欢 Ubuntu 的一点是它能够快速搜索。

我一直在寻找everything（Windows 工具）有时是一个替代方案，而且目前看来这是最好的。

但是，这个 Ubuntusystem search只搜索安装了操作系统的本地驱动器。

它不会搜索其他物理驱动器。

这可能吗？

答案1

Ubuntu 为此使用本地数据库。定位数据库是其一个版本，其配置文件位于/etc/updatedb.conf。

内容：

$ more  /etc/updatedb.conf
PRUNE_BIND_MOUNTS="yes"
# PRUNENAMES=".git .bzr .hg .svn"
PRUNEPATHS="/tmp /var/spool /media /home/.ecryptfs /var/lib/schroot"
PRUNEFS="NFS nfs nfs4 rpc_pipefs afs binfmt_misc proc smbfs autofs iso9660 
ncpfs coda devpts ftpfs devfs mfs shfs sysfs cifs lustre tmpfs usbfs 
udf fuse.glusterfs fuse.sshfs curlftpfs ecryptfs fusesmb devtmpfs"

正如您所看到的，很多位置尚未添加到索引中。

这是使用 locatedb 时添加路径的方法示例：

updatedb --localpaths '/ /media/usbdrive/dir/Music /media/usbdrive/dir/Photos'

我不确定是否需要，但是

sudo updatedb

将通过扫描您的磁盘来重新创建数据库，以防更改不会触发它。

让您的其他驱动器和分区自动安装在您的/etc/fstab：

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/nvme0n1p6 during installation
UUID=b40b3925-70ef-447f-923e-1b05467c00e7 /               ext4    errors=remount-ro 0       1

所有这些都将自动被索引以便快速搜索。例如：

$ time locate .bashrc
/etc/bash.bashrc
/etc/skel/.bashrc
/home/rick/.bashrc
/home/rick/.bashrc~
/home/rick/restore/.bashrc
/home/rick/restore/.bashrc~
/mnt/clone/etc/bash.bashrc
/mnt/clone/etc/skel/.bashrc
/mnt/clone/home/rick/.bashrc
/mnt/clone/home/rick/.bashrc~
/mnt/clone/home/rick/eyesome/.bashrc
/mnt/clone/home/rick/restore/.bashrc
/mnt/clone/home/rick/restore/.bashrc~

/usr/share/base-files/dot.bashrc
/usr/share/doc/adduser/examples/adduser.local.conf.examples/bash.bashrc
/usr/share/doc/adduser/examples/adduser.local.conf.examples/skel/dot.bashrc

real    0m0.868s
user    0m0.852s
sys     0m0.017s

甚至 Windows 文件也被编入索引：

$ time locate /cmd.exe
/mnt/c/Windows/SysWOW64/cmd.exe
/mnt/c/Windows/SysWOW64/en-US/cmd.exe.mui
/mnt/c/Windows/System32/cmd.exe

real    0m0.989s
user    0m0.980s
sys     0m0.008s

我添加了该time命令，以便您可以看到它花费的时间不到一秒钟。要计算所有索引文件的数量，请使用：

$ time locate * | wc -l
625125

real    0m39.088s
user    0m38.644s
sys     0m0.423s

39列出 625,125 个文件名并对其进行计数需要几秒钟。
