SHELL (str)

Path of current shell

Description

SHELL is an environmental variable containing the full path to the current shell -- which in our case is Murex.

This variable is set by Murex to conform to POSIX standards. However, being an environmental variable, it can be overwritten via export.

For Murex specific code, you are recommended to use MUREX_EXE, which is a reserved variable, and thus read only, if you require precision and safety.

Other Reserved Variables

• Numeric (str): Variables who's name is a positive integer, eg 0, 1, 2, 3 and above
• $., Meta Values (json): State information for iteration blocks
• ARGV (json): Array of the command name and parameters within a given scope
• COLUMNS (int): Character width of terminal
• EVENT_RETURN (json): Return values for events
• HOSTNAME (str): Hostname of the current machine
• MUREX_ARGV (json): Array of the command name and parameters passed to the current shell
• MUREX_EXE (path): Absolute path to running shell
• PARAMS (json): Array of the parameters within a given scope
• PWDHIST (json): History of each change to the sessions working directory
• PWD (path): Current working directory
• SELF (json): Meta information about the running scope.
• SHELL (str): Path of current shell
