I want a ksh script that parse two files (text files, actually my original files are .xls) - input data:

- one file file1 containig lines separated by spaces (or other delimiter)
- 2nd one file2 contain only one numerical value in a line (for simplicity but it might of the same form as the 1st)
- I know the 2nd value in file1 is also numerical and some of them can be found in file2

Output data:

The result should be a file that contains from the file1 only those lines whose 2nd field cannot be found in any line of file1.


I know this is easy, but I am too tired after a full hard working day so an expert can fix it in a minute.
I think it can be done in one line (complex?) command either....

sample input files AND desired output based on sample input PLS!

An example of line in file1 is like:



GAGLIARDI 7 GILBERTO TREZZANO - DG 30450 3TECH 3TECH 3TECH


All the lines are of this form.
Column 2 is interesting for me.

file2 might contain in one line only a number let's say 7:
- then do not output the line,
otherwise if 7 does not exist in file2
- then output the line (in a file).


At this moment both files are some .xls containing the same columns.

Both files contains thousands of lines...

a sample for file2, pls!
What do you consider a 'column' in file1 and file2?
In your sample file1, the 2-nd column has a value '7'. Is that correct?

A line in file1:

GAGLIARDI 743 GILBERTO TREZZANO - DG 30450 3TECH 3TECH 3TECH


A line in file2:

GAGLIARDI 743 GILBERTO TREZZANO - DG 30450 SupportCRM TeamLead 3TECH

assuming file1 and file2 are of the same format:

nawk 'FNR==NR {file2[$2];next} !($2 in file2)' file2 file1
