TCL: List Handling Commands
Most of the TCL commands for use in manipulating lists are available in iRules:
list - Create a list
split - Split a string into a proper Tcl list
join - Create a string by joining together list elements
concat - Join lists together
llength - Count the number of elements in a list
lindex - Retrieve an element from a list
lrange - Return one or more adjacent elements from a list
linsert - Insert elements into a list
lreplace - Replace elements in a list with new elements
lsort - Sort the elements of a list
lsearch - See if a list contains a particular element
The remaining documented list handling commands, lrepeat, lreverse, & dict, are not available within iRules. We’ll cover the commands from above that get the most traffic here on the forums.
