find and replace
Hello,
I would like some advice re the following. Suppose I have a file that contains many rows of data. The following line appears approx 1000 times in the file. "some other data" 1125 0.944 200.00 I would like the line to read (for all 1000 lines) "some other data" House 1125 0.944 200.00 The only constant value in the line is the 0.944 value. Thanks in advance.

assumed your exemple, on *nix try sed 's/\(.*\) \([0-9]*[0-9]\) \(0\.944\) \(.*\)/\1 House \2 \3 \4/' inputfile >outputfile NOTA: spaces are relevant \1 is "some other data" \2 are the digits after "some other data" and before 0.944 \3 is 0.944 \4 is all after 0.944 very similar syntax using perl.
