Below are couple of ways to list all the modules in Linux Hosts.

1. lsmod command.
Below lsmod command can be executed.

lsmod

Below is example snippet of lsmod command.

Module                  Size  Used by
bridge                114688  0
stp                    16384  1 bridge
llc                    16384  2 bridge,stp
ovmapi                 20480  1 [permanent]
ipmi_devintf           20480  0
ipmi_msghandler        49152  1 ipmi_devintf
rpcsec_gss_krb5        36864  0
auth_rpcgss            61440  1 rpcsec_gss_krb5
nfsv4                 524288  1
nfs                   282624  3 nfsv4
fscache                65536  2 nfsv4,nfs
lockd                  94208  1 nfs
sunrpc                344064  12 rpcsec_gss_krb5,auth_rpcgss,nfsv4,nfs,lockd

2. /proc/modules File

Below command can be executed to list content of /proc/modules File

cat /proc/modules

Below is example snippet of above command.

# more /proc/modules
bridge 114688 0 - Live 0xffffffffa0529000
stp 16384 1 bridge, Live 0xffffffffa0449000
