Top Forums Shell Programming and Scripting Compare values in two files. For matching rows print corresponding values from File 1 in File2. Post 302641733 by Santoshbn on Wednesday 16th of May 2012 12:44:18 PM

Thank you very much for the response Otheus. I tried using the solution, column2 in the output printed below seems fine against the two columns 1 & 3. But the output is missing the rest of the columns from file2. The last column has SQL Statment which runs into multiple lines, so I am mainly concerned as to how it will show up once that column is included in the output.

Code:
=> awk 'NR==FNR{A[$1]=$2;next} A[$1]{$5=A[$1];print}' file2 file1

paste

PASTE(1)						      General Commands Manual							  PASTE(1)

NAME

       paste - paste multiple files together

SYNOPSIS

       paste [-s] [-d list] file...

OPTIONS

       -d     Set delimiter used to separate columns to list.

       -s     Print files sequentially, file k on line k.

EXAMPLES

       paste file1 file2   # Print file1 in col 1, file2 in col 2

       paste -s f1 f2	   # Print f1 on line 1 and f2 on line 2

       paste -d : file1 file2
			   # Print the lines separated by a colon

DESCRIPTION

       Paste  concatenates  corresponding  lines of the given input files and writes them to standard output. The lines of the different files are
       separated by the delimiters given with the option -s. If no list is given, a tab is substituted for every linefeed, except  the	last  one.
       If  end-of-file	is hit on an input file, subsequent lines are empty.  Suppose a set of k files each has one word per line.  Then the paste
       output will have k columns, with the contents of file j in column j.  If the -s flag is given, then the first file is on line 1, the second
       file on line 2, etc.  In effect, -s turns the output sideways.

       If  a list of delimiters is given, they are used in turn.  The C escape sequences 
, 	, \, and  are used for linefeed, tab, backslash,
       and the null string, respectively.
