= What's shell.rb?
|
It realizes a wish to do execution of command and filtering like
|

|
sh/csh. However, Control statement which include sh/csh just uses
|
||||||
|
facility of ruby.
|

= Main classes
|
All shell objects have a each unique current directory. Any shell object
|
||||||
|
execute a command on relative path from current directory.

||||||
|
|
||||||
Every shell object has its own current working directory, and executes
|
** Filter
|
||||||
each command as if it stands in the directory.
|
|
||||||
|
|
||||||
--- Shell#cwd
|
Any result of command exection is a Filter. Filter include Enumerable,
|
||||||
--- Shell#dir
|
therefore a Filter object can use all Enumerable facility.
|
||||||
--- Shell#getwd
|
|
||||||
--- Shell#pwd
|
|
||||||
|
|
||||||
Returns the current directory
|
* Main methods
|
||||||
|
** Command definition
|
||||||
|
|
||||||
--- Shell#system_path
|
For executing a command on OS, you need to define it as a Shell
|
||||||
|
method.
|
||||||
|
|
||||||
Returns the command search path in an array
|
notice) Also, there are a Shell#system alternatively to execute the
|
||||||
|
command even if it is not defined.
|
||||||
|
|
||||||
--- Shell#umask
|
+ Shell.def_system_command(command, path = command)
|
||||||
|
Register command as a Shell method
|
||||||
|
|
||||||
Returns the umask
|
++ Shell.def_system_command "ls"
|

+ Shell.new
|
||||||
|
Shell creates a Shell object of which current directory is the process
|
||||||
|
current directory.
|
||||||
|
|
||||||
In order to execute a command on your OS, you need to define it as a
|
+ Shell.cd(path)
|
||||||
Shell method.
|
Shell creates a Shell object of which current directory is <path>.
|
||||||
|
|
||||||
Alternatively, you can execute any command via Shell#system even if it
|
** Process management
|
||||||
is not defined.
|
|
||||||
|
|
||||||
--- Shell.def_system_command(command, path = command)
|
+ jobs
|
||||||
|
The shell returns jobs list of scheduling.
|
||||||
|
|
||||||
