| 228 | USAGE: |
| 229 | bkots [ options ] [PATH...] |
| 230 | |
| 231 | POSITIONAL ARGUMENTS: |
| 232 | PATH Path(s) of file(s) or directory(ies) |
| 233 | |
| 234 | OPTIONS: |
| 235 | --dry-run |
| 236 | Do everything except run 'ots' commands. |
| 237 | -h, --help |
| 238 | Display help information. |
| 239 | --include-dotfiles |
| 240 | Include files and directories starting with '.' (not |
| 241 | included by default). |
| 242 | -r, --recursive |
| 243 | Consider files in dirs recursively. |
| 244 | --version |
| 245 | Display script version. |
| 246 | -v, --verbose |
| 247 | Display debugging info. |
| 248 | -- |
| 249 | Mark end of options. Interpret remaining arguments as |
| 250 | positional arguments. |
| 251 | |
| 252 | DESCRIPTION: |
| 253 | Scans files by file paths or directory paths provided by |
| 254 | positional arguments to see if Open Timestamps '.ots' file |
| 255 | exists. If so, attempt to upgrade and verify the '.ots' |
| 256 | file. If no '.ots' file exists, attempt to create one. |
| 257 | |
| 258 | Files with a dotfile parent directory located anywhere in the |
| 259 | file path are ignored by default. (e.g. 'HEAD' in |
| 260 | '/home/user/diary/.git/logs/HEAD' because of '.git'). Dotfiles |
| 261 | themselves are also ignored by default |
| 262 | (e.g. '/home/user/.gitconfig'). |
| 263 | |
| 264 | Files modified less than 1 minute ago are ignored. |
| 265 | |
