20 | /* Usage: strings [options] file... | |
21 | ||
22 | Options: | |
23 | --all | |
24 | -a | |
25 | - Do not scan only the initialized data section of object files. | |
26 | ||
27 | --print-file-name | |
28 | -f Print the name of the file before each string. | |
29 | ||
30 | --bytes=min-len | |
31 | -n min-len | |
32 | -min-len Print graphic char sequences, MIN-LEN or more bytes long, | |
33 | that are followed by a NUL or a newline. Default is 4. | |
34 | ||
35 | --radix={o,x,d} | |
36 | -t {o,x,d} Print the offset within the file before each string, | |
37 | in octal/hex/decimal. | |
38 | ||
39 | -o Like -to. (Some other implementations have -o like -to, | |
40 | others like -td. We chose one arbitrarily.) | |
41 | ||
8745eafa NC |
42 | --encoding={s,S,b,l,B,L} |
43 | -e {s,S,b,l,B,L} | |
44 | Select character encoding: 7-bit-character, 8-bit-character, | |
45 | bigendian 16-bit, littleendian 16-bit, bigendian 32-bit, | |
46 | littleendian 32-bit. | |

252b5132 | 48 | --target=BFDNAME |
3bf31ec9 | 49 | -T {bfdname} |
252b5132 RH |
50 | Specify a non-default object file format. |
51 | ||
52 | --help | |
53 | -h Print the usage message on the standard output. | |
54 | ||
55 | --version | |
56 | -v Print the program version number. | |
