Hi, just joined minutes ago. I am trying join tab-delimited files into a single file/table

Example, say I have these 4 files/tables:

ID value (table1)

Aa 22

Bb 28

Cc 32

Dd 50

ID value (table2)

Aa 34

Cc 112

Dd 77

Ee 89

Kk 124

ID value (table3)

Bb 75

Cc 91

Dd 132

ID value (table4)

Aa 66

Cc 94

Ee 213

Gg 250

The output after joining should look like this:

ID value1 value2 value3 value4

Aa 22 34 0 66

Bb 28 0 75 0

Cc 32 112 91 94

Dd 50 77 132 0

Ee 0 89 0 213

Gg 0 0 0 250

Kk 0 124 0 0

My best effort:

 #usr/bin/perl!
use strict;
#I opened all files (containg the tables) one by one; is #there a way 
+I can open all files at once?
open(FILEH1, "<table1.txt");
 while (my $file = <FILEH1>){
      chomp $file;
      my @file1 = split('\t', $file); #to pick IDs and #values => $fil
+e1[0] and $file1[1]
}

open(FILEH2, "<table2.txt");
#and continued to tables 3 and 4.

#And then I tried to collect the items which is where I got #stuck.

Your post has nothing to do with a reply to the original post (OP).

I suggest that you start a new question.

I see that you do understand how to use <code>...</code> tags, so format this critter a bit better.
