.. _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.
|
|
|
|
Example
|
|
-------
|
|
|
|
The following code will call the ls command. Note that ``fish`` does not support the use of shell variables as direct commands; ``eval`` can be used to work around this.
