awk compare specific columns from 2 files, print new file
Hello. I have two files. FILE1 was extracted from FILE2 and modified thanks to help from this post. Now I need to replace the extracted, modified lines into the original file (FILE2) to produce the FILE3.

FILE1

Code:
1466 55.27433 14.72050 -2.52E+03 3.00E-01 1.05E+04 2.57E+04

FILE3

I was able to do this by first extracting the lines from FILE2 that are in FILE1 > tmp using the post linked to above. Then I used to diff to get the remaining lines from FILE2 > tmp2. I edited tmp2 to remove extraneous symbols and used cat to combine tmp2 and FILE1. sort -n was the final command needed.

Pretty standard problem:
Code:
awk 'FNR==NR { r[$1] = $0; next; } r[$1] { print r[$1]; next } { print }' FILE1 FILE2 >FILE3

where FILE2 contains the ORIGINAL lines, and FILE1 contains the ones you want to replace, keyed on column 1.
