getpib - Qualcomm Atheros PIB Data Extractor
getpib file offset format [length]
This program is a companion to program setpib and is designed to support shell scripts. It extracts PIB file parameters so that a scripting language can evaluate, manipulate or store them with minimal effort. Good scripting skills and some imagination may be required to make effective use of this program.
Users having a detailed knowledge of PIB content and structure can make extremely effective use of this program; however, Atheros is under no obligation to provide customers with the offset, length or format of PIB file parameters.
This program is part of the Qualcomm Atheros Powerline Toolkit. See the AMP man page for an overview and installation instructions.
- c character
The appended character. Append this character each line of output instead of newline. Use this to create a comma separated list of value, for example, by specifying a comma.
|
-n |
Append a newline to the output. |
|||
|
-q |
Enable quiet mode which has no effect. |
|||
|
-v |
Verbose mode. Does nothing. |
-?,--help
Print program help summary on stdout. This option takes precedence over other options on the command line.
-!,--version
Print program version information on stdout. This option takes precedence over other options on the command line. Usethis option when sending screen dumps to Atheros Technical Support so that they know exactly which version of the Linux Toolkit you are using.
|
file |
The PIB filename. This argument is required and must appear first on the command line. No assumptions are made based on filename and no filename conventions are enforced; however, an invalid PIB file will be rejected. | ||
|
offset |
The data offset in bytes expressed in hexadecimal. This argument is required and must follow the filename. A leading "0x" prefix is optional. The data offset plus the data length cannot exceed the file extent. | ||
|
format |
The output format. This argument is required and must follow the offset. Some formats imply fixed data length. Others formats are for variable length data. The fixed data formats are byte, word, long, hfid, mac and key. The variable data formats are data and text. The formats are described in the next section. | ||
|
length |
The data length in bytes expressed in decimal. This argument is only required for the the data formats data and text. The data offset plus the data length cannot exceed the file extent. The data length cannot exceed 1024. |
|
byte |
Extract 1 byte and display it as an unsigned decimal integer value. The offset advances byte before starting another extraction. | ||
|
word |
Extract 2 consecutive bytes and display them as an unsigned decimal integer value after endian conversion. The offset advances bytes before starting another extraction. | ||
|
long |
Extract 4 consecutive bytes and display them as an unsigned decimal integer value after endian conversion. The offset advances 4 bytes before starting another extraction. | ||
|
huge |
Extract 8 consecutive bytes and display them as an unsigned decimal integer value after endian conversion. The offset advances 8 bytes before starting another extraction. | ||
|
xbyte |
Extract 1 byte and display it as a hexadecimal integer value. The offset advances byte before starting another extraction. | ||
|
xword |
Extract 2 consecutive bytes and display them as a hexadecimal integer value after endian conversion. The offset advances bytes before starting another extraction. | ||
|
xlong |
Extract 4 consecutive bytes and display them as a hexadecimal integer value after endian conversion. The offset advances 4 bytes before starting another extraction. | ||
|
xhuge |
Extract 8 consecutive bytes and display them as a hexadecimal integer value after endian conversion. The offset advances 8 bytes before starting another extraction. |
data length
Extract the specified number of bytes and display them as a hexadecimal string with no punctuation to separate octets. The offset advances length bytes before starting another extraction. The minimum length is 1. The maximum length is 1024.
|
mac |
Extract 6 bytes and display them as a colon-separated hexadecimal string. The offset advances 6 bytes before starting another extraction. This is similar to "data 6" but colons separate each octet. | ||
|
key |
Extract 16 bytes and display them as a colon-separated hexadecimal string. The offset advances 16 bytes before starting another extraction. This is similar to "data 16" but colons separate each octet. | ||
|
hfid |
Extract 64 consecutive bytes and display them as an ASCII string that terminates at the first non-printable character. The offset advances 64 bytes before starting another extraction. This is equivalent to "text 64". |
skip length
Advance the specified number of bytes without displaying anything. The offset advances by length bytes before starting another extraction. The minimum length is 1. The maximum length is 1024.
text length
Extract the specified number of bytes and display them as an ASCII string that terminates at the first non-printable character. The offset advances the specified number of bytes before starting another extraction.
accesspassword
Extract 65 consecutive bytes and display them as an ASCII string that terminates at the first non-printable character. The offset advances 65 bytes before starting another extraction. This format is equivalent to "text 65".
accessusername
Extract 33 consecutive bytes and display them as an ASCII string that terminates at the first non-printable character. The offset advances 33 bytes before starting another extraction. This format is equivalent to "text 33".
adminpassword
Extract 33 consecutive bytes and display them as an ASCII string that terminates at the first non-printable character. The offset advances 33 bytes before starting another extraction. This format is equivalent to "text 33".
adminusername
Extract 33 consecutive bytes and display them as an ASCII string that terminates at the first non-printable character. The offset advances 33 bytes before starting another extraction. This format is equivalent to "text 33".
password
Extract 257 consecutive bytes and display them as an ASCII string that terminates at the first non-printable character. The offset advances 257 bytes before starting another extraction. This format is equivalent to "text 257".
|
url |
Extract 257 consecutive bytes and display them as an ASCII string that terminates at the first non-printable character. The offset advances 257 bytes before starting another extraction. This format is equivalent to "text 257". |
username
Extract 257 consecutive bytes and display them as an ASCII string that terminates at the first non-printable character. The offset advances 257 bytes before starting another extraction. This format is equivalent to "text 257".
The following example extracts one byte from offset 01F7 of PIB file abc.pib and displays it as an unsigned decimal integer string. No length specification is needed because the byte format has an implied length of 1 byte. The displayed value is 232 because the byte format is decimal. We could have specified "data 1" to display the byte in hexadecimal. The return prompt appears on the display line because option -n was omitted.
# getpib abc.pib
01F7 byte
232#
The next example extracts two bytes at offset 01F7 and displays them as a hexadecimal string. A length of 2 is needed because the data format is variable length. We could have specified "word" to display these bytes as an unsigned decimal integer string. The hexadecimal string consists two octets E8 and 8A. The first byte is the same one extracted in the last example. The return prompt appears on a new line because option -n was present.
# getpib abc.pib
01F7 data 2 -n
E88A
