NAME

       lsmtd - list memory technology devices

SYNOPSIS

       lsmtd [options] [device...]

DESCRIPTION

       lsmtd  lists  information  about  all available or the specified MTD and UBI devices.  The
       lsmtd command reads the sysfs filesystem to gather information. Alternatively, the  procfs
       filesystem and ioctl interfaces are used, should the sysfs filesystem not be available.

       The command prints all MTD and UBI devices in a pretty-printed list format by default.

       The  default  output  is  subject  to change. So whenever possible, you should avoid using
       default outputs in your scripts.  Always  explicitly  define  expected  columns  by  using
       --output columns-list in environments where a stable output is required.

       Use lsmtd --help to get a list of all available columns.

OPTIONS

       -b, --bytes
              Print  columns  with  size quantities (e.g. erase block size) in bytes instead of a
              human-readable format.

       -h, --help
              Display a help text and exit.

       -i, --ascii
              Only use ascii characters for pretty printing.

       -J, --json
              Use JSON output format. All potentially unsafe  characters  in  string  values  are
              escaped with JSON escape sequences or hex-escaped (\u<code>).

       -l, --list
              Use a pretty-printed list output format (default).

       -m, --no-ubi
              Do not display information about UBI devices or volumes.

       -n, --noheadings
              Do not print column headings when using raw or list output format.

       -o, --output list
              Specify  which  output columns to print.  Use --help to get a list of all supported
              columns.

              The default list of columns may be extended if list  is  specified  in  the  format
              +list (e.g. lsmtd -o +EB-SIZE).

       -O, --output-all
              Output all available columns.

       -P, --pairs
              Produce output in the form of key="value" pairs.  All potentially unsafe characters
              are hex-escaped (\x<code>).

       -r, --raw
              Produce output in raw format. All potentially  unsafe  characters  are  hex-escaped
              (\x<code>).

       -u, --si-units
              Display human readable sizes as powers of ten rather than powers of two.

       -V, --version
              Print version information and exit.

       -x, --sort column
              Sort output lines by column.

NOTES

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