Manual_scripting – mikrotik wiki

Scripting host provides a way to automate some router maintenance tasks by means of executing user-defined scripts bounded to some event occurrence.

The events used to trigger script execution include, but are not limited to the System Scheduler, the Traffic Monitoring Tool, and the Netwatch Tool generated events.

RouterOS script is divided into number of command lines.


Create database link Command lines are executed one by one until the end of script or until runtime error occur.

A physical line is a sequence of characters terminated by an end-of-line (EOL) sequence. Database form Any of the standard platform line termination sequences can be used:

A comment starts with a hash character (#) and ends at the end of the physical line. Data recovery process Whitespace or any other symbols are not allowed before hash symbol. Database training Comments are ignored by syntax. Data recovery hardware If (#) character appear inside string it is not considered a comment.

Two or more physical lines may be joined into logical lines using backslash character (\). Best database software A line ending in a backslash cannot carry a comment. Database gui A backslash does not continue a comment. Data recovery technician A backslash does not continue a token except for string literals. Database engine tuning advisor A backslash is illegal elsewhere on a line outside a string literal.

Whitespace can be used to separate tokens. Data recovery rates Whitespace is necessary between two tokens only if their concatenation could be interpreted as a different token.

Variables can be used only in certain regions of the script. Database developer salary These regions are called scopes. Database backup and recovery Scope determines visibility of the variable. Yale b database There are two types of scopes – global and local.

User can define its own groups to block access to certain variables, these scopes are called local scopes. Sybase database Each local scope is enclosed in curly braces (“{ }”).

Every variable, except for built in RouterOS variables, must be declared before usage by local or global keywords. Database design Undefined variables will be marked as undefined and will result in compilation error.

Valid characters in variable names are letters and digits. Database 3 normal forms If variable name contains any other character, then variable name should be put in double quotes. Database for dummies Example:

If variable is initially defined without value then variable data type is set to nil, otherwise data type is determined automatically by scripting engine. A database is a collection of Sometimes conversion from one data type to another is required. Library database It can be achieved using data conversion commands. Database node Example:

change selected items parameter, more than one parameter can be specified at the time. Data recovery after format Parameter can be unset by specifying ‘!’ before parameter.

export configuration from current menu and its sub-menus (if present). Database 2015 If file parameter is specified output will be written to file with extension ‘.rsc’, otherwise output will be printed to console. Data recovery nyc Exported commands can be imported by import command

Import command is available from root menu and is used to import configuration from files created by export command or written manually by hand.

More than one parameter can be specified at a time, for example, /ip route print count-only interval=1 where interface=”ether1″ Loops and conditional statements
