19 | /* Usage: strings [options] file... | |
20 | ||
21 | Options: | |
22 | --all | |
23 | -a | |
7fac9594 NC |
24 | - Scan each file in its entirety. |
25 | ||
26 | --data | |
27 | -d Scan only the initialized data section(s) of object files. | |
252b5132 RH |
28 | |
29 | --print-file-name | |
30 | -f Print the name of the file before each string. | |
31 | ||
32 | --bytes=min-len | |
33 | -n min-len | |
34 | -min-len Print graphic char sequences, MIN-LEN or more bytes long, | |
35 | that are followed by a NUL or a newline. Default is 4. | |
36 | ||
37 | --radix={o,x,d} | |
38 | -t {o,x,d} Print the offset within the file before each string, | |
39 | in octal/hex/decimal. | |
40 | ||
334ac421 EA |
41 | --include-all-whitespace |
42 | -w By default tab and space are the only whitepace included in graphic | |
43 | char sequences. This option considers all of isspace() valid. | |
44 | ||
252b5132 RH |
45 | -o Like -to. (Some other implementations have -o like -to, |
46 | others like -td. We chose one arbitrarily.) | |
47 | ||
8745eafa NC |
48 | --encoding={s,S,b,l,B,L} |
49 | -e {s,S,b,l,B,L} | |
50 | Select character encoding: 7-bit-character, 8-bit-character, | |
51 | bigendian 16-bit, littleendian 16-bit, bigendian 32-bit, | |
52 | littleendian 32-bit. | |
d132876a | 53 | |
252b5132 | 54 | --target=BFDNAME |
3bf31ec9 | 55 | -T {bfdname} |
252b5132 RH |
56 | Specify a non-default object file format. |
57 | ||
58 | --help | |
59 | -h Print the usage message on the standard output. | |
60 | ||
61 | --version | |
ffbe5983 | 62 | -V |
252b5132 RH |
63 | -v Print the program version number. |
