Concatenating two files
Aloha
I am new to the linux environment and would like to pose this question: File1.txt --------- 01659942.pdf: 01659943.pdf:x+2г42T0 AHDRB!9KH%+R)K@@!$ 01659944.pdf: 01659945.pdf: File2.txt --------- << /CreationDate (D:20060419121647-05'00') /Title (A 8-32 kbit/s Scalable Wideband Speech and Audio Coding Candidate for ITU-T G729EV Standardization) /Producer (PDFlib+PDI 6.0.3 \(COM/Win32\)) /ModDate (D:20060609142615-04') << /CreationDate (D:20060419121647-05'00') /Title (An Embedded Scalable Wideband Codec based on the GSM EFR Codec) /Producer (PDFlib+PDI 6.0.3 \(COM/Win32\)) /ModDate (D:20060609142616-04') << /CreationDate (D:20060419121647-05'00') /Title (Multiple Description Coding for Voice over IP using Sinusoidal Speech Coding) /Producer (PDFlib+PDI 6.0.3 \(COM/Win32\)) /ModDate (D:20060609142617-04') << /CreationDate (D:20060419121647-05'00') /Title (RESYNCHRONIZATION OF THE ADAPTIVE CODEBOOK IN A CONSTRAINED CELP CODEC AFTER A FRAME ERASURE) /Producer (PDFlib+PDI 6.0.3 \(COM/Win32\)) /ModDate (D:20060609142618-04') Desired Resultant File (FileR.txt) ======================> 01659942.pdf:A 8-32 kbit/s Scalable Wideband Speech and Audio Coding Candidate for ITU-T G729EV Standardization 01659943.pdf:An Embedded Scalable Wideband Codec based on the GSM EFR Codec 01659944.pdf:Multiple Description Coding for Voice over IP using Sinusoidal Speech Coding 01659945.pdf:RESYNCHRONIZATION OF THE ADAPTIVE CODEBOOK IN A CONSTRAINED CELP CODEC AFTER A FRAME ERASURE Instructions: ============= Please cut and paste the contents of the two files in blank text files. Question ======== I would like to know what is the command required to concatenate the first two files (looks like a vertical concatenation) in order to obtain the desired output file. I have found a similar post but there is no explanation in that post that will help me extend the logic enumerated in that case to my question. So I shall really appreciate if the person clarifying would be a bit generous with his explanation. Thanks, Ingrid |
Ingrid,
You need to parse both files to temp once, containing just what you need and then "paste" them together: cut -d":" -f1 <file1> > temp_file1 cut -d"(" -f3 <file2> >temp_file2 cut -d")" -f1 <temp_file2> >temp2_file2 paste -d":" temp_file1 temp2_file2 > result_file PS: Try one by one command and see on the screen what you're getting PPS: Always, always create a back-up. |
