.SH NAME
llvm-strings \- print strings
.SH SYNOPSIS
.sp
\fBllvm\-strings\fP [\fIoptions\fP] [\fIinput...\fP]
.SH DESCRIPTION
.sp
\fBllvm\-strings\fP is a tool intended as a drop\-in replacement for GNU\(aqs
\fBstrings\fP, 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.
.sp
\fBllvm\-strings\fP looks for strings in each \fBinput\fP file specified.
Unlike GNU \fBstrings\fP it looks in the entire input file, regardless of
file format, rather than restricting the search to certain sections of object
files. If "\fB\-\fP" is specified as an \fBinput\fP, or no \fBinput\fP is specified,
the program reads from the standard input stream.
.SH EXAMPLE
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
$ cat input.txt
bars
foo
wibble blob
$ llvm\-strings input.txt
bars
wibble blob
