This makes it so we link to the very top of the document instead of a special anchor we manually include. So clicking e.g. :doc:`string <cmds/string>` will link you to cmds/string.html instead of cmds/string.html#cmd-string. I would love to have a way to say "this document from the root of the document path", but that doesn't appear to work, I tried `/cmds/string`. So we'll just have to use cmds/string in normal documents and plain `string` from other commands.

.. _cmd-eval:

|
|
eval - evaluate the specified commands
|

======================================

Synopsis
|
|
--------
|
|
|
|
.. synopsis::
|
|
|
|
eval [COMMANDS ...]
|
|
|
|
Description
|
|
-----------
|
|
**eval** evaluates the specified parameters as a command.
|
|
If more than one parameter is specified, all parameters will be joined using a space character as a separator.
|
|
|
|
If the command does not need access to stdin, consider using :doc:`source <source>` instead.
|
|
|
|
If no piping or other compound shell constructs are required, variable-expansion-as-command, as in ``set cmd ls -la; $cmd``, is also an option.
|
|
|
|
Example
|
|
-------
|
|
|
|
The following code will call the ls command and truncate each filename to the first 12 characters.
|
|
|
|
::
|
|
|
|
set cmd ls \| cut -c 1-12
|
|
eval $cmd
