pysaurio 0.2.1

A tool for searching & extracting information from multiple text files.

This package contains two tools: Raptor y Reptar

Raptor

Raptor for extracting and displaying information from a set of files of the same type; and creating a single file with all the selected information.

The information in the files may be in multiple rows:

PC01.txt:
User=ms123
Name=Mayra Sanz
OS=GNU/Linux
IP=10.226.140.1

But, also, the information may be in several columns. It is possible to read data from multiple fields in a single line:

PC01.log:
User: ms123     Name: Mayra Sanz
OS: GNU/Linux   IP: 10.226.140.1

Example: data from the following files:

PC01.txt:
User=ms123
Name=Mayra Sanz
OS=GNU/Linux
IP=10.226.140.1

PC02.txt:
User=lt001
Name=Luis Toribio
OS=GNU/Linux
IP=10.226.140.2

PC03.txt:
User=co205
Name=Clara Osto
OS=Win
IP=10.226.140.3

… You can create a CSV file with the following information:

users.csv:
User,Name,OS,IP
MS123,Mayra Sanz,GNU/linux,10.226.140.1
LT001,Luis Toribio,GNU/linux,10.226.140.2
CO205,Clara Osto,Win,10.226.140.3

To achieve this you need to create a template (.rap) with Raptor, which is similar to an INI file with the following information:

users.rap:
[General]
description = Get list of users
extension = txt
prefix = PC
output_folder = txt
input_folder = txt
output_file = users.csv
delimiter = ,
quotechar = "
include_header = 1
include_file = 0
include_record_num = 0
include_empty_record = 0
search_multiple = 0
alternate_header =
search_multiple = 0

[Fields]
user = User=
name = Name=
os = OS=
ip = IP=

[Rules]
rule1 = ('user', 'UPPER')

To create .rap template (If the .rap template exists it is not saved):

from pysaurio import Raptor
rap1 = Raptor()
rap1.description = 'Get list of users'
rap1.extension = 'txt'
rap1.prefix = 'PC'
rap1.input_folder = 'txt'
rap1.output_folder = 'txt'
rap1.output_file = 'users.csv'
rap1.delimiter = ','
rap1.quotechar = '"'
rap1.include_header = '1'
rap1.include_file = '1'
rap1.include_record_num = '1'
rap1.include_empty_record = '0'
rap1.search_multiple = '0'
rap1.alternate_header = ''
rap1.fields['user'] = 'User='
rap1.fields['name'] = 'Name='
rap1.fields['os'] = 'OS='
rap1.fields['ip'] = 'IP='
rap1.rules.append(('user', 'UPPER'))
rap1.rules.append(('name', 'REMOVEFROM', ' '))
rap1.Save("users.rap")
del rap1

Attribute List:

• prefix: files must begin with this string

• input_folder: folder of files to read

• output_folder: output folder to save file with result

• search_multiple: ‘0’ or ‘1’

• alternate_header: alternative text of the report header

• fields: dictionary with fieldnames and search string (read template)

• record: dictionary with fieldnames and values (read template)

• rules: list of rules (read template)

• list_files: list of filenames to read (auto)

• record_counter: number of records (auto)

• errors: list of errors (auto)

• number_errors: number of errors after you open or save a template

Functions available for rules:

• rule1 = (fieldname, ‘SUBSTR’, postion_initial, lenght)

• rule1 = (fieldname, ‘REPLACE’, search_string, replace_string)

• rule1 = (fieldname, ‘REPLACEALL’, search_string, replace_string)

• rule1 = (fieldname, ‘UPPER’)

• rule1 = (fieldname, ‘LOWER’)

• rule1 = (fieldname, ‘REVERSE’)

• rule1 = (fieldname, ‘REMOVE’)

• rule1 = (fieldname, ‘FIELDISDATA’)

• rule1 = (fieldname, ‘REMOVEFROM’, ‘string’)

• rule1 = (fieldname, ‘REMOVETO’, ‘string’)

Opens template (.rap) and creates (.csv) file from the data read from multiple text files:

from pysaurio import Raptor
import csv

rap2 = Raptor()
rap2.Open('users.rap')
if rap2.number_errors == 0:
    file_csv = open(rap2.output_file, 'w', newline='')
    csv_output = csv.writer(file_csv,
                            delimiter=rap2.delimiter,
                            quotechar=rap2.quotechar,
                            quoting=csv.QUOTE_MINIMAL)
    if rap2.include_header == '1':
        fields_list = rap2.BuildHeader()
        print(fields_list)
        csv_output.writerow(fields_list)

    for row in rap2.list_files:
        valid_record, new_record = rap2.BuildRow(row)
        new_record = rap2.ApplyRules(new_record)
        if valid_record:
            new_record = list(new_record.values())
            print(new_record)
            csv_output.writerow(new_record)
    file_csv.close()
else:
    print(rap2.ShowError())
del rap2

Reptar

Reptar allows merge files, including only the necessary lines.

Example: data from the following files:

PCS01.txt:
User,Name,OS,IP
ms123,Mayra Sanz,GNU/Linux,10.226.140.1
lt001,Luis Toribio,GNU/Linux,10.226.140.2
co205,Clara Osto,Win,10.226.140.3

PCS02.txt:
User,Name,OS,IP
nn345,Nadia Pacheco,Win,10.226.140.4
jm401,Juan Madrid,GNU/Linux,10.226.140.5

… You can create a file with the following information:

Linux.csv:
User,Name,OS,IP
MS124,MAYRA SANZ,GNU/LINUX,10.226.140.1
LT001,LUIS TORIBIO,GNU/LINUX,10.226.140.2
CO205,CLARA OSTO,WIN,10.226.140.3
JM401,JUAN MADRID,GNU/LINUX,10.226.140.5

In this example, lines that contain the text “Linux” or beginning with the text “co205” are included:

from pysaurio import Reptar
rep1 = Reptar()
rep1.description = 'Get list of Linux users'
rep1.extension = 'txt'
rep1.prefix = 'PCS'
rep1.input_folder = 'txt'
rep1.output_folder = 'txt'
rep1.output_file = 'Linux.csv'
rep1.include_header = '1'
rep1.include_file = '0'
rep1.include_record_num = '0'
rep1.alternate_header = ''
rep1.lines.append(('INCLUDE', 'Linux'))
rep1.lines.append(('INCLUDRE', '^co205'))
rep1.rules.append(('line', 'UPPER'))
rep1.Save("linux.rep")
del rep1

# Opens .rep template and create file with output information

rep2 = Reptar()
rep2.Open('linux.rep')
if rep2.number_errors == 0:
    file_csv = open(rep2.output_file, 'w')
    if rep2.include_header == '1':
        header = rep2.BuildHeader(rep2.list_files[0])
        print(header)
        file_csv.write(header + '\n')

    for row in rep2.list_files:
        current_file = open(rep2.input_folder + row, 'rb')
        while True:
            new_record = current_file.readline()
            new_record = new_record.decode("utf-8", "ignore")
            if not new_record: break
            valid_record, new_record = rep2.BuildRow(new_record, row)
            if valid_record:
                new_record = rep2.ApplyRules(new_record)
                print(new_record)
                file_csv.write(new_record + '\n')
        current_file.close()
    file_csv.close()
else:
    print(rep2.ShowError())
del rep2

Functions available for including and excluding lines:

• line1 = (‘EXCLUDE’, ‘string’)

• line1 = (‘INCLUDE’, ‘string’)

• line1 = (‘EXCLUDRE’, ‘regex’) # See module re

• line1 = (‘INCLUDRE’, ‘regex’) # See module re

The package contains more examples and data files to test.
