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

252b5132 | 47 | --target=BFDNAME |
3bf31ec9 | 48 | -T {bfdname} |
252b5132 RH |
49 | Specify a non-default object file format. |
50 | ||
51 | --help | |
52 | -h Print the usage message on the standard output. | |
53 | ||
54 | --version | |
ffbe5983 | 55 | -V |
252b5132 RH |
56 | -v Print the program version number. |
