| 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 | |
| 42 | --encoding={s,b,l,B,L} |
| 43 | -e {s,b,l,B,L} |
| 44 | Select character encoding: single-byte, bigendian 16-bit, |
| 45 | littleendian 16-bit, bigendian 32-bit, littleendian 32-bit |
| 46 | |
| 47 | --target=BFDNAME |
| 48 | Specify a non-default object file format. |
| 49 | |
| 50 | --help |
| 51 | -h Print the usage message on the standard output. |
| 52 | |
| 53 | --version |
| 54 | -v Print the program version number. |
