Adds synopses for those commands missing them. Moves all synopsis sections to code blocks. This improves the appearance, although highlighting as fish code may not be the ideal appearance.

.. _cmd-eval:
|
|
|
|
eval - evaluate the specified commands
|

======================================
|
|
|
|
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 your command does not need access to stdin, consider using ``source`` instead.
|
|
|
|
If no piping or other compound shell constructs are required, variable-expansion-as-command, as in ``set cmd ls; $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
