# lsmod 显示已载入系统的模块 ## 补充说明 **lsmod命令** 用于显示已经加载到内核中的模块的状态信息。执行lsmod命令后会列出所有已载入系统的模块。Linux操作系统的核心具有模块化的特性，应此在编译核心时，务须把全部的功能都放入核心。您可以将这些功能编译成一个个单独的模块，待需要时再分别载入。 ### 语法 ``` lsmod ``` ### 实例 ``` [root@LinServ-1 ~]# lsmod Module Size Used by ipv6 272801 15 xfrm_nalgo 13381 1 ipv6 crypto_api 12609 1 xfrm_nalgo ip_conntrack_ftp 11569 0 xt_limit 6721 2 xt_state 6209 2 ip_conntrack 53665 2 ip_conntrack_ftp,xt_state nfnetlink 10713 1 ip_conntrack xt_tcpudp 7105 6 xt_multiport 7233 1 iptable_filter 7105 1 ip_tables 17029 1 iptable_filter x_tables 17349 5 xt_limit,xt_state,xt_tcpudp,xt_multiport,ip_tables dm_mirror 24393 0 dm_multipath 27213 0 scsi_dh 12481 1 dm_multipath video 21193 0 backlight 10049 1 video sbs 18533 0 power_meter 16461 0 hwmon 7365 1 power_meter i2c_ec 9025 1 sbs dell_wmi 8401 0 wmi 12137 1 dell_wmi button 10705 0 battery 13637 0 asus_acpi 19289 0 ac 9157 0 lp 15849 0 snd_hda_intel 401453 0 snd_seq_dummy 7877 0 snd_seq_oss 32577 0 snd_seq_midi_event 11073 1 snd_seq_oss snd_seq 49585 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi_event snd_seq_device 11725 3 snd_seq_dummy,snd_seq_oss,snd_seq snd_pcm_oss 42817 0 snd_mixer_oss 19009 1 snd_pcm_oss snd_pcm 72517 2 snd_hda_intel,snd_pcm_oss ide_cd 40161 0 snd_timer 24517 2 snd_seq,snd_pcm tpm_tis 16713 0 r8169 43077 0 snd_page_alloc 14281 2 snd_hda_intel,snd_pcm tpm 19041 1 tpm_tis i2c_i801 12737 0 mii 9409 1 r8169 serio_raw 10693 0 i2c_core 24897 2 i2c_ec,i2c_i801 snd_hwdep 12869 1 snd_hda_intel tpm_bios 11073 1 tpm cdrom 36577 1 ide_cd pcspkr 7105 0 parport_pc 29669 1 sg 36973 0 snd 57797 9 snd_hda_intel,snd_seq_oss,snd_seq,snd_seq_device,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer,snd_hwdep parport 37513 2 lp,parport_pc soundcore 11553 1 snd dm_raid45 67273 0 dm_message 6977 1 dm_raid45 dm_region_hash 15681 1 dm_raid45 dm_log 14785 3 dm_mirror,dm_raid45,dm_region_hash dm_mod 63993 4 dm_mirror,dm_multipath,dm_raid45,dm_log dm_mem_cache 9537 1 dm_raid45 ata_piix 23749 4 libata 158085 1 ata_piix sd_mod 25409 6 scsi_mod 144277 4 scsi_dh,sg,libata,sd_mod ext3 126281 3 jbd 57705 1 ext3 uhci_hcd 25421 0 ohci_hcd 24937 0 ehci_hcd 34509 0 ``` * 第1列：表示模块的名称。 * 第2列：表示模块的大小。 * 第3列：表示依赖模块的个数。 * 第4列：表示依赖模块的内容。 通常在使用lsmod命令时，都会采用类似`lsmod | grep -i ext3`这样的命令来查询当前系统是否加载了某些模块。 --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://hezhiqiang.gitbook.io/linux/ming-ling/lsmod.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
