Hello Cristoforo,

I am trying to read n number of *.txt files as argument inputs. Each file contains infinite n number of lines in the file. I want to extract the the 4th element of each line. Each element of each line is separated with a column ":".

Line example:

After collecting each element from each line I want to put them on an array so I am able to manipulate the values of each element.

The reason that I am using array of arrays is that I do not know the number of *.txt files that I am going to use.

As a second step I am trying to print the collected values based on order of the files separated with a space in between.

Sample of the expected output:

Line_1_3 Line_3_3 Line_4_3
Line_2_3          Line_5_3
                  Line_6_3
                  Line_7_3
[download]

Each column represents the *.txt file that was loaded. For example if we had loaded the sample.txt it would be column 1, sample_2.txt would be column 2 and sample_3.txt would be column 3.

I hope this explains more and produces less confusion.

Thanks for your time and effort to assist me.
