If the file type is unrecognizable, or if strings is +reading from stdin then it will always display all of the printable +sequences that it can find. +.PP +For backwards compatibility any file that occurs after a command-line +option of just \fB\-\fR will also be scanned in full, regardless of +the presence of any \fB\-d\fR option. +.PP +\&\fBstrings\fR is mainly useful for determining the contents of +non-text files. +.SH "OPTIONS" +.IX Header "OPTIONS" +.IP "\fB\-a\fR" 4 +.IX Item "-a" +.PD 0 +.IP "\fB\-\-all\fR" 4 +.IX Item "--all" +.IP "\fB\-\fR" 4 +.IX Item "-" +.PD +Scan the whole file, regardless of what sections it contains or +whether those sections are loaded or initialized. Normally this is +the default behaviour, but strings can be configured so that the +\&\fB\-d\fR is the default instead. +.Sp +The \fB\-\fR option is position dependent and forces strings to +perform full scans of any file that is mentioned after the \fB\-\fR +on the command line, even if the \fB\-d\fR option has been +specified. +.IP "\fB\-d\fR" 4 +.IX Item "-d" +.PD 0 +.IP "\fB\-\-data\fR" 4 +.IX Item "--data" +.PD +Only print strings from initialized, loaded data sections in the +file. This may reduce the amount of garbage in the output, but it +also exposes the strings program to any security flaws that may be +present in the \s-1BFD\s0 library used to scan and load sections. Strings +can be configured so that this option is the default behaviour. In +such cases the \fB\-a\fR option can be used to avoid using the \s-1BFD\s0 +library and instead just print all of the strings found in the file. +.IP "\fB\-f\fR" 4 +.IX Item "-f" +.PD 0 +.IP "\fB\-\-print\-file\-name\fR" 4 +.IX Item "--print-file-name" +.PD +Print the name of the file before each string. +.IP "\fB\-\-help\fR" 4 +.IX Item "--help" +Print a summary of the program usage on the standard output and exit. +.IP "\fB\-\fR\fImin-len\fR" 4 +.IX Item "-min-len" +.PD 0 +.IP "\fB\-n\fR \fImin-len\fR" 4 +.IX Item "-n min-len" +.IP "\fB\-\-bytes=\fR\fImin-len\fR" 4 +.IX Item "--bytes=min-len" +.PD +Print sequences of displayable characters that are at least +\&\fImin-len\fR characters long. If not specified a default minimum +length of 4 is used. The distinction between displayable and +non-displayable characters depends upon the setting of the +\&\fB\-e\fR and \fB\-U\fR options. Sequences are always terminated +at control characters such as new-line and carriage-return, but not +the tab character. +.IP "\fB\-o\fR" 4 +.IX Item "-o" +Like \fB\-t o\fR.

Useful for finding wide character strings. (\fBl\fR +and \fBb\fR apply to, for example, Unicode \s-1UTF\-16/UCS\-2\s0 encodings). +.IP "\fB\-U\fR \fI[d|i|l|e|x|h]\fR" 4 +.IX Item "-U [d|i|l|e|x|h]" +.PD 0 +.IP "\fB\-\-unicode=\fR\fI[default|invalid|locale|escape|hex|highlight]\fR" 4 +.IX Item "--unicode=[default|invalid|locale|escape|hex|highlight]" +.PD +Controls the display of \s-1UTF\-8\s0 encoded multibyte characters in strings. +The default (\fB\-\-unicode=default\fR) is to give them no special +treatment, and instead rely upon the setting of the +\&\fB\-\-encoding\fR option. The other values for this option +automatically enable \fB\-\-encoding=S\fR. +.Sp +The \fB\-\-unicode=invalid\fR option treats them as non-graphic +characters and hence not part of a valid string. All the remaining +options treat them as valid string characters. +.Sp +The \fB\-\-unicode=locale\fR option displays them in the current +locale, which may or may not support \s-1UTF\-8\s0 encoding. The +\&\fB\-\-unicode=hex\fR option displays them as hex byte sequences +enclosed between \fI<>\fR characters. The \fB\-\-unicode=escape\fR +option displays them as escape sequences (\fI\euxxxx\fR) and the +\&\fB\-\-unicode=highlight\fR option displays them as escape sequences +highlighted in red (if supported by the output device).

This option +allows you to supply any string to be used as the output record +separator. Useful with \-\-include\-all\-whitespace where strings +may contain new-lines internally. +.IP "\fB@\fR\fIfile\fR" 4 +.IX Item "@file" +Read command-line options from \fIfile\fR. The options read are +inserted in place of the original @\fIfile\fR option. If \fIfile\fR +does not exist, or cannot be read, then the option will be treated +literally, and not removed. +.Sp +Options in \fIfile\fR are separated by whitespace. A whitespace +character may be included in an option by surrounding the entire +option in either single or double quotes. Any character (including a +backslash) may be included by prefixing the character to be included +with a backslash. The \fIfile\fR may itself contain additional +@\fIfile\fR options; any such options will be processed recursively. +.SH "SEE ALSO" +.IX Header "SEE ALSO" +\&\fIar\fR\|(1), \fInm\fR\|(1), \fIobjdump\fR\|(1), \fIranlib\fR\|(1), \fIreadelf\fR\|(1) +and the Info entries for \fIbinutils\fR. +.SH "COPYRIGHT" +.IX Header "COPYRIGHT" +Copyright (c) 1991\-2023 Free Software Foundation, Inc. +.PP +Permission is granted to copy, distribute and/or modify this document +under the terms of the \s-1GNU\s0 Free Documentation License, Version 1.3 +or any later version published by the Free Software Foundation; +with no Invariant Sections, with no Front-Cover Texts, and with no +Back-Cover Texts.
