merging rows into new file based on rows and first column
I have 2 files,
file01= 7 columns, row unknown (but few)
file02= 7 columns, row unknown (but many)
now I want to create an output with the first field that is shared in both of them and then subtract the results from the rest of the fields and print there
e.g.
file 01
James
0
50
25
10
50
30
Mark
0
50
25
10
50
30
file02
James
5
100
50
10
150
60
Dean

Mark

John

output

Mark

I know there is a command join to join them and then use awk but is there a better way to do it?
Using the input files you specified and the commands that you say you ran, I get:
(note that there are trailing spaces on both lines above because you are printing the value of the undefined variable g) rather than the
which is the output you said you wanted.
Given that (except for the names in column one) both input records for James and Mark are identical in file01 AND (except for the names in column one) both input records for James and Mark are also identical in file02, why would you expect different values in columns two through seven in the output?
From you description, I had assumed you wanted something like
which given the input files you specified would produce
which matches what you were getting with your combination of join and awk (except for the trailing space), but uses tabs instead of spaces as the field separator.

I have a space delimited text file. I want to extract rows where the third column has 0 as a value and write those rows into a new space delimited text file. How do I go about doing that? Thanks! (2 Replies)

I have a tab delimited text file where the first column can take on three different values : 100, 150, 250. I want to extract all the rows where the first column is 100 and put them into a separate text file and so on. This is what my text file looks like now:

I need to delete rows based on the number of lines in a different file, I have a piece of code with me working but when I merge with my C application, it doesnt work.
