llvm-strings - print strings
|
|
============================
|
|
|
|
.. program:: llvm-strings
|
|
|
|
SYNOPSIS
|
|
--------
|
|
|
|
:program:`llvm-strings` [*options*] [*input...*]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
:program:`llvm-strings` is a tool intended as a drop-in replacement for GNU's
|
|
:program:`strings`, which looks for printable strings in files and writes them
|
|
to the standard output stream. A printable string is any sequence of four (by
|
|
default) or more printable ASCII characters. The end of the file, or any other
|
|
byte, terminates the current sequence.
|
|
|
|
:program:`llvm-strings` looks for strings in each ``input`` file specified.
|
|
Unlike GNU :program:`strings` it looks in the entire input file, regardless of
|
|
file format, rather than restricting the search to certain sections of object
|
|
files. If "``-``" is specified as an ``input``, or no ``input`` is specified,
|
|
the program reads from the standard input stream.
|
|
|
|
EXAMPLE
|
|
-------
|
|
|
|
.. code-block:: console
|
|
|
|
$ cat input.txt
|
|
bars
|
|
foo
|
|
wibble blob
|
|
$ llvm-strings input.txt
|
|
bars
|
|
wibble blob
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
.. option:: --all, -a
|
|
|
|
Silently ignored. Present for GNU :program:`strings` compatibility.
|
|
|
|
.. option:: --bytes=<length>, -n
|
|
|
|
Set the minimum number of printable ASCII characters required for a sequence of
|
|
bytes to be considered a string. The default value is 4.
|
|
|
|
.. option:: --help, -h
|
|
|
|
Display a summary of command line options.
|
|
|
|
.. option:: --help-list
|
|
|
|
Display an uncategorized summary of command line options.
|
|
|
|
.. option:: --print-file-name, -f
|
|
|
|
Display the name of the containing file before each string.
|
|
|
|
Example:
|
|
|
|
.. code-block:: console
|
|
|
|
$ llvm-strings --print-file-name test.o test.elf
|
|
test.o: _Z5hellov
|
|
test.o: some_bss
|
|
test.o: test.cpp
|
|
test.o: main
|
|
test.elf: test.cpp
|
|
test.elf: test2.cpp
|
|
test.elf: _Z5hellov
|
|
test.elf: main
|
|
test.elf: some_bss
|
|
|
|
.. option:: --radix=<radix>, -t
|
|
|
|
Display the offset within the file of each string, before the string and using
|
|
the specified radix. Valid ``<radix>`` values are ``o``, ``d`` and ``x`` for
|
|
octal, decimal and hexadecimal respectively.
|
|
|
|
Example:
|
|
|
|
.. code-block:: console
|
|
|
|
$ llvm-strings --radix=o test.o
|
|
1054 _Z5hellov
