7.2.6 hexdump

Dump the contents of a file to standard output in hex format.

Syntax

hexdump [ -j bytes | --skip-bytes=bytes ] [ -N bytes | --read-bytes=bytes ] 
   [ --aio=naio ] [ -x ] [{ -w | --wallet } wallet-location ] 
   [{ -T | --trace } trace-level ] filename

Command Options

The options for the hexdump command are:

filename: Specifies the file being output.
-j, --skip-bytes: Optionally specifies the number of input bytes to skip.
-N, --read-bytes: Optionally specifies the number of bytes to read and output.
--aio: Optionally specifies the number of async I/Os to use. The default value is 4.
-x: Displays the file contents in hex notation. This is the default behavior anyway.
-w, --wallet: Optionally specifies the path to the Exascale wallet directory.
-T, --trace: Optionally enables tracing and sets the trace level to 1 (minimum tracing), 2 (medium tracing), or 3 (maximum tracing).

If the $ADR_BASE environment variable is set, the trace file is written to:
```
$ADR_BASE/diag/EXC/xsh_<username>/<hostname>/trace/xsh_<date>.trc
```
Otherwise, the trace file is written to:
```
/tmp/diag/EXC/xsh_<username>/<hostname>/trace/xsh_<date>.trc
```
