Options:
--all
-a
- - Do not scan only the initialized data section of object files.
+ - Scan each file in its entirety.
+
+ --data
+ -d Scan only the initialized data section(s) of object files.
--print-file-name
-f Print the name of the file before each string.
-t {o,x,d} Print the offset within the file before each string,
in octal/hex/decimal.
+ --include-all-whitespace
+ -w By default tab and space are the only whitepace included in graphic
+ char sequences. This option considers all of isspace() valid.
+
-o Like -to. (Some other implementations have -o like -to,
others like -td. We chose one arbitrarily.)
-T {bfdname}
Specify a non-default object file format.
+ --output-separator=sep_string
+ -s sep_string String used to separate parsed strings in output.
+ Default is newline.
+
--help
-h Print the usage message on the standard output.
