cat hosts | xargs -I{} ssh root@{} hostname
```
- Use null character delimiter to manage filenames with whitespaces, example `locate -0 patern | xargs -0 ls -al` or `find / -print0 -type d | xargs -0 ls -al`.
To iterate on filenames containing whitespaces in a for loop, set your IFS to only '\n' using `IFS=$'\n'`.
- Prefer the `-0` or `-print0` options to enable null characters to delimit filenames. This better supports filenames with whitespace.Example : `locate -0 pattern | xargs -0 ls -al` or `find / -print0 -type d | xargs -0 ls -al`. To iterate on filenames containing whitespace in a for loop, set your IFS to only '\n' using `IFS=$'\n'`. Always surround your bash variables with `"`.
- `pstree -p` is a helpful display of the process tree.
