llvm-strings - print strings

SYNOPSIS

llvm-strings [options] [input...]

DESCRIPTION

llvm-strings is a tool intended as a drop-in replacement for GNU’s 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.

llvm-strings looks for strings in each input file specified. Unlike GNU 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 

$ catinput.txt
bars
foo
wibble blob
$ llvm-stringsinput.txt
bars
wibble blob

OPTIONS

--all, -a

Silently ignored. Present for GNU strings compatibility.

--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.

--help, -h

Display a summary of command line options.

--print-file-name, -f

Display the name of the containing file before each string.

Example:

$ llvm-strings--print-file-nametest.otest.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
--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:

$ llvm-strings--radix=otest.o
 1054 _Z5hellov
 1066 .rela.text
 1101 .comment
 1112 some_bss
 1123 .bss
 1130 test.cpp
 1141 main
$ llvm-strings--radix=dtest.o
 556 _Z5hellov
 566 .rela.text
 577 .comment
 586 some_bss
 595 .bss
 600 test.cpp
 609 main
$ llvm-strings-txtest.o
 22c _Z5hellov
 236 .rela.text
 241 .comment
 24a some_bss
 253 .bss
 258 test.cpp
 261 main
--version

Display the version of the llvm-strings executable.

@<FILE>

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

EXIT STATUS

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