I have files (~1k) that look (basically) like this: NAME1.txt NAME ATTR VALUE NAME1

I have files (~1k) that look (basically) like this:

NAME1.txt
NAME    ATTR    VALUE
NAME1   x       1      
NAME1   y       2
...

NAME2.txt
NAME    ATTR    VALUE
NAME2   x       19
NAME2   y       23
...

Where the ATTR collumn is same in everyfile and the name column is just some version of the filename. I would like to combine them together into 1 file that looks like:

All_data.txt
ATTR    NAME1_VALUE    NAME2_VALUE    NAME3_VALUE ...
X       1              19             ...
y       2              23             ...
...

Is there simple way to do this with just command line utilities or will I have to resort to writing some script?

Thanks

    You need to write a script.
    gawk is the obvious candidate
    You could create an associative array in a BEGIN block, using FILENAME as the KEY and
    ATTR ” ” VALUE
    values as the value.
    Then create your output in an END block.
    gawk can process all txt files together by using *txt as the filename

    It’s a bit optimistic to expect there to be a ready made command to do exactly what you want.
    Very few command join data horizontally.
