Usage | ||||
|

Description | ||||
This command is useful to execute variable command sequences. <command> is first evaluated as a normal parameter (thus identifiers and variables are substituted) then the evaluated string is executed as a command sequence. -q causes eval to run quietly and don't display any errors in the inner command. -f causes eval to ignore the errors inside <command> and continue execution. This command may be used to rebind the <command> to a specified window. <command> shares the local variables with this command scope so you can easily exchange data with it. Remember that <command> is still a normal parameter and it must be enclosed in quotes if youwant it to be a complex command sequence. eval propagates the <command> return value. |
