## SYNOPSIS

**acpidump** \[*options*\]\
 **acpitbl** \[*filename*\]\
 **acpixtract** \[*options*\] \[*filename*\]

## DESCRIPTION

This manual page documents briefly the **acpidump** , **acpitbl** and **acpixtract** commands. **acpidump** options are described below while **acpitbl** and **acpixtract** can only take an optional filename to read data from (STDIN if omitted) and output the result to STDOUT.

## OPTIONS

acpidump options are as follow:

- **-a, --addr 0x1234**

  look for tables at this phisical address.

- **-t, --table DSDT**

  only dump table with DSDT signature.

- **-o, --output filename**

  redirect output from stdin to filename.

- **-b, --binary**

  dump data in binary form rather than in hex-dump format.

- **-l, --lenght 0x456**

  works only with --addr, dump phisical memory region without trying to understand it's contents.

- **-s, --skip 2**

  skip 2 tables of the given name and output only 3rd one.

- **-h, --help**

  outputs an help message.

- acpixtract only option is:

  - **-n instance\_number**

  prints Nth instance of target table, default is 1.

## EXAMPLES

Dump the DSDT table to the file DSDT.aml in binary format (this can be disassembled later with [iasl(1)](/iasl/1.md):

acpidump -b -t DSDT -o DSDT.aml

Show the FACP table:

acpidump -t FACP \| acpixtract \| acpitbl

Dump the table header or contents of a raw ACPI table:

acpidump -t FACP -b \| acpitbl\
 cat email \| acpixtract FACP \| acpitbl
