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=, -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:: --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=, -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 1066 .rela.text 1101 .comment 1112 some_bss 1123 .bss 1130 test.cpp 1141 main $ llvm-strings --radix=d test.o 556 _Z5hellov 566 .rela.text 577 .comment 586 some_bss 595 .bss 600 test.cpp 609 main $ llvm-strings -t x test.o 22c _Z5hellov 236 .rela.text 241 .comment 24a some_bss 253 .bss 258 test.cpp 261 main

.. option:: --version

Display the version of the :program:llvm-strings executable.

.. option:: @

Read command-line options from response file <FILE>.

EXIT STATUS

:program:llvm-strings exits with a non-zero exit code if there is an error. Otherwise, it exits with code 0.
