llvm-strings - print strings

llvm-strings [/options/] [/input…/]

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.

#+begin_quote

      $ cat input.txt
      bars
      foo
      wibble blob
      $ llvm-strings input.txt
      bars
      wibble blob

#+end_quote

–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:

#+begin_quote

#+begin_quote

        $ 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

#+end_quote #+end_quote

–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:

#+begin_quote

#+begin_quote

        $ 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

#+end_quote #+end_quote

–version

Display the version of the llvm-strings executable.

@<FILE>

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

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