#  `pdftl help`

Get help

## Details
If a `help` argument is given, the remaining arguments are
scanned for a keyword. This can be `tag:<tagname>`, or one of the
operation names, or an option name, or a special help topic, or an
alias. If a match is found, the help is printed. Tags are printed
at the end of any help topics which have tags.

By default, colors are used if printing directly to the
terminal, and usually not in other situations (e.g., if
the output is redirected). If the environment variable
`FORCE_COLORS` is set, then colors should appear in all
cases.

The special help topic `all` is particularly interesting.
## Examples

> Get all help. This is nice if you set `FORCE_COLORS=1` and pipe the output to `less -R`, with the complete command `FORCE_COLORS=1 pdftl help all | less -R`.
```
pdftl help all
```

> Get help topics tagged with `encryption`
```
pdftl help tag:encryption
```

> Gather all examples from the various help topics
```
