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

252b5132 | 49 | --target=BFDNAME |
3bf31ec9 | 50 | -T {bfdname} |
252b5132 RH |
51 | Specify a non-default object file format. |
52 | ||
53 | --help | |
54 | -h Print the usage message on the standard output. | |
55 | ||
56 | --version | |
ffbe5983 | 57 | -V |
252b5132 RH |
58 | -v Print the program version number. |
