NAME

6       lsmtd - list memory technology devices
7

SYNOPSIS

9       lsmtd [options] [device...]
10

DESCRIPTION

12       lsmtd  lists  information  about all available or the specified MTD and
13       UBI devices.  The lsmtd command reads the sysfs  filesystem  to  gather
14       information.  Alternatively, the procfs filesystem and ioctl interfaces
15       are used, should the sysfs filesytem not be available.
16
17       The command prints all MTD and UBI devices  in  a  pretty-printed  list
18       format by default.
19
20       The  default  output  is  subject  to change. So whenever possible, you
21       should avoid using default outputs in your scripts.  Always  explicitly
22       define  expected columns by using --output columns-list in environments
23       where a stable output is required.
24
25       Use lsmtd --help to get a list of all available columns.
26

OPTIONS

28       -b, --bytes
29              Print columns with size quantities (e.g. erase  block  size)  in
30              bytes instead of a human-readable format.
31
32       -h, --help
33              Display a help text and exit.
34
35       -i, --ascii
36              Only use ascii characters for pretty printing.
37
38       -J, --json
39              Use  JSON  output  format.  All potentially unsafe characters in
40              string values are escaped with JSON  escape  sequences  or  hex-
41              escaped (\u<code>).
42
43       -l, --list
44              Use a pretty-printed list output format (default).
45
46       -m, --no-ubi
47              Do not display information about UBI devices or volumes.
48
49       -n, --noheadings
50              Do  not print column headings when using raw or list output for‐
51              mat.
52
53       -o, --output list
54              Specify which output columns to print.  Use --help to get a list
55              of all supported columns.
56
57              The default list of columns may be extended if list is specified
58              in the format +list (e.g. lsmtd -o +EB-SIZE).
59
60       -O, --output-all
61              Output all available columns.
62
63       -P, --pairs
64              Produce output in the form of  key="value"  pairs.   All  poten‐
65              tially unsafe characters are hex-escaped (\x<code>).
66
67       -r, --raw
68              Produce  output in raw format. All potentially unsafe characters
69              are hex-escaped (\x<code>).
70
71       -u, --si-units
72              Display human readable sizes as powers of ten rather than powers
73              of two.
74
75       -V, --version
76              Print version information and exit.
77
78       -x, --sort column
79              Sort output lines by column.
80

NOTES

82       If  the  --bytes option is not specified, the JSON output format prints
83       sizes as string values even if they do not have a suffix.
