Computer correction
i would like to correct the sample data that i have:

Code:
test-01
               abc-01     name1
               abc-02     name2
               abc-03     name3
test-02
               abc-20     name4
               abc-21     name5
test-03
               abc-22     name6
               abc-23     name7

will have an output of:

test-01 abc-01 name1
test-01 abc-02 name2
test-01 abc-03 name3
test-02 abc-20 name4
test-02 abc-21 name5
test-03 abc-22 name6
test-03 abc-23 name7

Code:
:p
#!/usr/bin/awk
NF == 0 { next }                                # Skip empty lines
NF == 1 { tag = $1; next }                # Pick up the tag
NF == 3 { print tag, $(NF-1), $NF  }   # Print lines with data

How'd it work? NF was never 3.

Hammer & Screwdriver modified it a little bit
i changed NF == 3 to NF == 2

but what if my data contains same NF?

for example, instead of "test01" i have "test01 testname"?

thanks,

Then you have to find some other way to characterize your data. F'rinstance, your "tag" lines always seem to start at the beginning of a line while the "appended" lines do not, so replace "NF==1" with "/^[^ ]/", i.e., the line begins with a non-blank character.

In ssow's version, you can delete the "NF==0 { next}" line, because you're only printing on lines with 2 fields (per your change).

The man page. Seriously. If you want a little more hand holding, O'Reilly's book Sed And Awk.
