Ignore Failed Read (GNU tar 1.35)

#### 4.3.3 Ignore Failed Read

`--ignore-failed-read` ¶

  Do not exit with nonzero if there are mild problems while reading.

This option has effect only during creation. It instructs tar to treat as mild conditions any missing or unreadable files (directories), or files that change while reading. Such failures don’t affect the program exit code, and the corresponding diagnostic messages are marked as warnings, not errors. These warnings can be suppressed using the `--warning=failed-read` option (see Controlling Warning Messages).
