Looking for some help, I have two files, one is a large list of various names the other is coordinates. both files start each line with an 8 digit code. I want to lookup 8 digit line code from File1 and copy the line contents to all matching line codes in File2.

(File1) Only one occurence of hash / name.

136667ED ap1_01_a_ap1_01_rails_07
035B337C ap1_01_a_arrows_005
79546F82 ap1_01_a_centreline_010
0E1D31E7 prop_bush_med_02

(File2) Some have multiple hash copies like 0E1D31E7, with different coordinates.

136667ED -1294.6945,-2376.0317,21.8279
035B337C -1314.6719,-2721.7378,12.9467
79546F82 -1283.1066,-2529.9771,12.9635
0E1D31E7 1919.4160,-1814.3889,160.5210
0E1D31E7 1919.9885,-2628.2529,0.7537  
0E1D31E7 192.0235,-2603.1790,4.9978   
0E1D31E7 192.1050,4950.3540,389.4736

Below is how I would like them, The 8 Digit code / name, copied into any code line match in file 2.

136667ED -1294.6945,-2376.0317,21.8279  136667ED ap1_01_a_ap1_01_rails_07  
035B337C -1314.6719,-2721.7378,12.9467  035B337C ap1_01_a_arrows_005       
79546F82 -1283.1066,-2529.9771,12.9635  79546F82 ap1_01_a_centreline_010   
0E1D31E7 1919.4160,-1814.3889,160.5210  0E1D31E7 prop_bush_med_02          
0E1D31E7 1919.9885,-2628.2529,0.7537    0E1D31E7 prop_bush_med_02          
0E1D31E7 192.0235,-2603.1790,4.9978     0E1D31E7 prop_bush_med_02          
0E1D31E7 192.1050,4950.3540,389.4736    0E1D31E7 prop_bush_med_02

Join lines of text with repeated beginning

This may work, I dont know how to run any of these commands. I'm using windows.

  • What does "Some have multiple hash copies" mean?  Please add example(s).  Please do not respond in comments; edit your question to make it clearer and more complete.  P.S. It's confusing that your "large list" file is actually smaller than the other one. – Scott Jun 13 '16 at 18:19

Based on your input, here is the output using the paste command to standard out:

$ paste File1 File2
136667ED ap1_01_a_ap1_01_rails_07   136667ED -1294.6945,-2376.0317,21.8279
035B337C ap1_01_a_arrows_005    035B337C -1314.6719,-2721.7378,12.9467
79546F82 ap1_01_a_centreline_010    79546F82 -1283.1066,-2529.9771,12.9635

Since you have large files, you may consider redirecting the output to a file by using paste File1 File2 > mergedfile.

  • I'm using windows 10, Have installed CoreUtils for Windows - GnuWin32 Could you explain more how to do paste File1 File2 Thanks – Poly Jun 13 '16 at 18:49
  • @Poly If the files are in the same directory, run command as above; if not, give paste two arguments -- the path to File1 followed by path to File2 – KM. Jun 13 '16 at 19:02
  • I'm just running through in cmd, It does look like it will take a while seems to be working. Will this update or output a new text file? – Poly Jun 13 '16 at 19:12
  • @Poly updated answer – KM. Jun 13 '16 at 19:26
  • It never matched any of the 8 digit start codes, to the output – Poly Jun 13 '16 at 19:51

Using join and a shell that understands process substitution:

$ join <(sort file2) <(sort file1)
035B337C -1314.6719,-2721.7378,12.9467 ap1_01_a_arrows_005
0E1D31E7 1919.4160,-1814.3889,160.5210 prop_bush_med_02
0E1D31E7 1919.9885,-2628.2529,0.7537 prop_bush_med_02
0E1D31E7 192.0235,-2603.1790,4.9978 prop_bush_med_02
0E1D31E7 192.1050,4950.3540,389.4736 prop_bush_med_02
136667ED -1294.6945,-2376.0317,21.8279 ap1_01_a_ap1_01_rails_07
79546F82 -1283.1066,-2529.9771,12.9635 ap1_01_a_centreline_010

Or, to duplicate the joining field in the middle of the output:

$ join -o0,1.2,0,2.2 <(sort file2) <(sort file1)
035B337C -1314.6719,-2721.7378,12.9467 035B337C ap1_01_a_arrows_005
0E1D31E7 1919.4160,-1814.3889,160.5210 0E1D31E7 prop_bush_med_02
0E1D31E7 1919.9885,-2628.2529,0.7537 0E1D31E7 prop_bush_med_02
0E1D31E7 192.0235,-2603.1790,4.9978 0E1D31E7 prop_bush_med_02
0E1D31E7 192.1050,4950.3540,389.4736 0E1D31E7 prop_bush_med_02
136667ED -1294.6945,-2376.0317,21.8279 136667ED ap1_01_a_ap1_01_rails_07
79546F82 -1283.1066,-2529.9771,12.9635 79546F82 ap1_01_a_centreline_010

For nicer columns:

$ join -o0,1.2,0,2.2 <(sort file2) <(sort file1) | column -t
035B337C  -1314.6719,-2721.7378,12.9467  035B337C  ap1_01_a_arrows_005
0E1D31E7  1919.4160,-1814.3889,160.5210  0E1D31E7  prop_bush_med_02
0E1D31E7  1919.9885,-2628.2529,0.7537    0E1D31E7  prop_bush_med_02
0E1D31E7  192.0235,-2603.1790,4.9978     0E1D31E7  prop_bush_med_02
0E1D31E7  192.1050,4950.3540,389.4736    0E1D31E7  prop_bush_med_02
136667ED  -1294.6945,-2376.0317,21.8279  136667ED  ap1_01_a_ap1_01_rails_07
79546F82  -1283.1066,-2529.9771,12.9635  79546F82  ap1_01_a_centreline_010
