デフォルトで実行すると、CPUやカーネルのバージョン、HDDやメモリの容量が確認出来る。
ここで、ヘルプの内容を見てみよう。

$ inxi -h
inxi supports the following options. You can combine them, or list them one by one. Examples:
inxi -v4 -c6 OR inxi -bDc 6. If you start inxi with no arguments, it will show the short form.

The following options if used without -F, -b, or -v will show just option line(s): A, C, D, G,
I, M, N, P, R, S, f, i, n, o, p, l, u, r, s, t - you can use these alone or together to show
just the line(s) you want to see. If you use them with -v [level], -b or -F, it will show the
full output for that line along with the output for the chosen verbosity level.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Output Control Options:
-A Audio/sound card information.
-b Basic output, short form. Like inxi -v 2, only minus hard disk names.
-c Color schemes. Scheme number is required. Color selectors run a color selector option
prior to inxi starting which lets you set the config file value for the selection.
Supported color schemes: 0-32 Example: inxi -c 11
Color selectors for each type display (NOTE: irc and global only show safe color set):
94 Console, out of X
95 Terminal, running in X - like xTerm
96 Gui IRC, running in X - like Xchat, Quassel, Konversation etc.
97 Console IRC running in X - like irssi in xTerm
98 Console IRC not in X
99 Global - Overrides/removes all settings. Setting specific removes global.
-C CPU output, including per CPU clockspeed (if available).
-d Optical drive data. Same as -Dd. See also -x and -xx.
-D Full hard Disk info, not only model, ie: /dev/sda ST380817AS 80.0GB. See also -x and -xx.
Disk total used percentage includes swap partition size(s).
-f All cpu flags, triggers -C. Not shown with -F to avoid spamming. ARM cpus show 'features'.
-F Full output for inxi. Includes all Upper Case line letters, plus -s and -n. Does not show
extra verbose options like -x -d -f -u -l -o -p -t -r
-G Graphic card information (card, display server type/version, resolution, glx renderer,
version).
-i Wan IP address, and shows local interfaces (requires ifconfig network tool). Same as
-Nni. Not shown with -F for user security reasons, you shouldn't paste your local/wan IP.
-I Information: processes, uptime, memory, irc client (or shell type), inxi version.
-l Partition labels. Default: short partition -P. For full -p output, use: -pl (or -plu).
-M Machine data. Motherboard, Bios, and if present, System Builder (Like Lenovo). Older
systems/kernels without the required /sys data can use dmidecode instead, run as root.
Dmidecode can be forced with -! 33
-n Advanced Network card information. Same as -Nn. Shows interface, speed, mac id, state,
etc.
-N Network card information. With -x, shows PCI BusID, Port number.
-o Unmounted partition information (includes UUID and LABEL if available). Shows file system
type if you have file installed, if you are root OR if you have added to /etc/sudoers
(sudo v. 1.7 or newer) Example: <username> ALL = NOPASSWD: /usr/bin/file
-p Full partition information (-P plus all other detected partitions).
-P Basic partition information (shows what -v 4 would show, but without extra data). Shows,
if detected: / /boot /home /tmp /usr /var. Use -p to see all mounted partitions.
-r Distro repository data. Supported repo types: APT; PACMAN; PISI; YUM; URPMQ; Ports.
-R RAID data. Shows RAID devices, states, levels, and components, and extra data with
-x/-xx. md-raid: If device is resyncing, shows resync progress line as well.
-s Sensors output (if sensors installed/configured): mobo/cpu/gpu temp; detected fan speeds.
Gpu temp only for Fglrx/Nvidia drivers. Nvidia shows screen number for > 1 screens.
-S System information: host name, kernel, desktop environment (if in X), distro
-t Processes. Requires extra options: c (cpu) m (memory) cm (cpu+memory). If followed by
numbers 1-20, shows that number of processes for each type (default: 5; if in irc,
max: 5): -t cm10
Make sure to have no space between letters and numbers (-t cm10 - right, -t cm 10 -
wrong).
-u Partition UUIDs. Default: short partition -P. For full -p output, use: -pu (or -plu).
-v Script verbosity levels. Verbosity level number is required. Should not be used with -b
or -F
Supported levels: 0-7 Example: inxi -v 4
0 Short output, same as: inxi
1 Basic verbose, -S + basic CPU + -G + basic Disk + -I.
2 Networking card (-N), Machine (-M) data, shows basic hard disk data (names only),
and, if present, basic raid (devices only, and if inactive, notes that). similar
to: inxi -b
3 Advanced CPU (-C), network (-n) data, and switches on -x advanced data option.
4 Partition size/filled data (-P) for (if present): /, /home, /var/, /boot. Shows
full disk data (-D).
5 Audio card (-A); sensors (-s), partition label (-l) and UUID (-u), short form of
optical drives, standard raid data (-R).
6 Full partition (-p), unmounted partition (-o), optical drive (-d), full raid;
triggers -xx.
7 Network IP data (-i); triggers -xxx.
-w Local weather data/time. To check an alternate location, see: -W <location>. For extra
weather data options see -x, -xx, and -xxx.
-W <location> Supported options for <location>: postal code; city, state/country;
latitude/longitude. Only use if you want the weather somewhere other than the machine
running inxi. Use only ascii characters, replace spaces in city/state/country names with
'+'. Example: inxi -W new+york,ny
-x Adds the following extra data (only works with verbose or line output, not short form):
-C CPU Flags, Bogomips on Cpu;
-d Extra optical drive data; adds rev version to optical drive.
-D Hdd temp with disk data if you have hddtemp installed, if you are root OR if you
have added to /etc/sudoers (sudo v. 1.7 or newer)
Example: <username> ALL = NOPASSWD: /usr/sbin/hddtemp
-G Direct rendering status for Graphics (in X).
-G (for single gpu, nvidia driver) screen number gpu is running on.
-i IPv6 as well for LAN interface (IF) devices.
-I System GCC, default. With -xx, also show other installed GCC versions. If running
in console, not in IRC client, shows shell version number, if detected. Init/RC
Type and runlevel (if available).
-N -A Version/port(s)/driver version (if available) for Network/Audio;
-N -A -G Network, audio, graphics, shows PCI Bus ID/Usb ID number of card.
-R md-raid: Shows component raid id. Adds second RAID Info line: raid level; report on
drives (like 5/5); blocks; chunk size; bitmap (if present). Resync line, shows
blocks synced/total blocks. zfs-raid: Shows raid array full size; available size;

available.
-N Chip vendor:product ID for each nic.
-R md-raid: Superblock (if present); algorythm, U data. Adds system info line (kernel
support,read ahead, raid events). If present, adds unused device line. Resync line,
shows progress bar.
-S Display manager (dm) in desktop output, if in X (like kdm, gdm3, lightdm).

-S Panel/shell information in desktop output, if in X (like gnome-shell, cinnamon,
mate-panel).
-w -W Location (uses -z/irc filter), weather observation time, wind chill, heat index,
dew point (shows extra lines for data where relevant).
-y Required extra option: integer, 80 or greater. Set the output line width max. Overrides
IRC/Terminal settings or actual widths. If used with -h, put -y option first.
Example: inxi -y 130
-z Security filters for IP/Mac addresses, location, user home directory name. Default on for
irc clients.
-Z Absolute override for output filters. Useful for debugging networking issues in irc for
example.

Additional Options:

-H This help menu, plus developer options. Do not use dev options in normal
operation!
--recommends Checks inxi application dependencies + recommends, and directories, then shows
what package(s) you need to install to add support for that feature.
-V --version inxi version information. Prints information then exits.

Debugging Options:
-% Overrides defective or corrupted data.
-@ Triggers debugger output. Requires debugging level 1-14 (8-10 - logging of data). Less
than 8 just triggers inxi debugger output on screen.
1-7 On screen debugger output
8 Basic logging
9 Full file/sys info logging
10 Color logging.
The following create a tar.gz file of system data, plus collecting the inxi output to
file. To automatically upload debugger data tar.gz file to ftp.techpatterns.com:
inxi -xx@ <11-14>
For alternate ftp upload locations: Example: inxi -! ftp.yourserver.com/incoming -xx@ 14
11 With data file of xiin read of /sys.
12 With xorg conf and log data, xrandr, xprop, xdpyinfo, glxinfo etc.
13 With data from dev, disks, partitions, etc., plus xiin data file.
14 Everything, full data collection.

Advanced Options:
