matchPattern

Parse command line strings and add tokens

Match pattern column to stringToMatch column and assigning tags based on a match.

Command line strings are input to a function, which tokenizes the command line arguments. Distinguishes between command line arguments and the values passed into the arguments. Then interprets metadata about the arguments and values.

The first step is properly parsing command line parameters the way the shell interpreter would parse them for interpretation before they are handed to the executable that will operate on those arguments.

Usage Details

matchPattern(table:TableReference, stringToMatch:String, patternTable:TableReference, pattern:String, tags:String, matchType:String)

Parameters:
table(TableReference)-The table to which the operate is applied
stringToMatch(String)-Column in a 'table' to match to pattern
patternTable(TableReference)-Table that contains patterns, tags and a matchType columns
pattern(String)-pattern column in a patternTable
tags(String)-tags column to assign after pattern matches
matchType(String)-match type of a pattern: '0'-> string match on each tokens in a string, '1'-> regex match on a tokens, '2'-> regex match on a whole string without tokenization.

Returns:
Input table with additional commandline_tags column is returned. Please read documentation page for usage of this operator

Shortly, this operator does following procedures, for each row in a table it will do regex matching to each of the pattern column values inside patternTable, and if it matches then assigns the tag that you provided in tags column.

Example

Input
table that contains the command lines for auto tagging (commandsTable)

command_line
powershell.exe abc:emil user
cmd.exe word /progfiles
ls.exe -a -f -n20

table that contains patterns (patternTable)

pattern tag type
[-/]([0-9a-z]+)arg_%s1
:([0-9a-z]+)user_%s1
([0-9a-z]+)purearg_%s1
matchPattern(commandsTable, "command_line", patternsTable, "pattern", "tags", "type")

Output

it should produce the following output.

field1 field2
powershell.exe abc :emil user{"exec":"powershell", "tags":["purearg_abc","user_emil","purearg_user"]}
cmd.exe word /progfiles {"exec":"cmd", "tags":["purearg_word","arg_progfiles"]}
ls.exe -a -f -n20 {"exec":"ls", "tags":["arg_a","arg_f","arg_n20"]}
