Compare columns of multiple files and print those unique string from File1 in an output file.
Hi,
I have multiple files that each contain one column of strings:
File1:
Code:
123abc
456def
789ghi
File2:
Code:
123abc
456def
891jkl
File3:
Code:
234mno
123abc
456def
In total I have 25 of these type of file.
I want to compare the strings in File 1 with the 24 other files and Print in my output ONLY those strings in File 1 that do not appear in ANY other file.
Can anyone help me?
Thanks!

Since you didn't include CODE tags I can't be sure whether or not you intended for there to be an empty line at the start of File1. When I added CODE tags for you, I assumed that you did not want an empty line at the start of File1.
Please use CODE tags so we don't have to guess.

Good morning all,
I have a problem that is one step beyond a standard awk compare.

join
JOIN(1) General Commands Manual JOIN(1)NAME
join - relational database operator
SYNOPSIS
join [ options ] file1 file2
DESCRIPTION
Join forms, on the standard output, a join of the two relations specified by the lines of file1 and file2. If file1 is `-', the standard
input is used.
File1 and file2 must be sorted in increasing ASCII collating sequence on the fields on which they are to be joined, normally the first in
each line.
There is one line in the output for each pair of lines in file1 and file2 that have identical join fields. The output line normally con-
sists of the common field, then the rest of the line from file1, then the rest of the line from file2.
Fields are normally separated by blank, tab or newline. In this case, multiple separators count as one, and leading separators are dis-
carded.
These options are recognized:
-an In addition to the normal output, produce a line for each unpairable line in file n, where n is 1 or 2.
-e s Replace empty output fields by string s.
-jn m Join on the mth field of file n. If n is missing, use the mth field in each file.
-o list
Each output line comprises the fields specified in list, each element of which has the form n.m, where n is a file number and m is a
field number.
-tc Use character c as a separator (tab character). Every appearance of c in a line is significant.
SEE ALSO sort(1), comm(1), awk(1)BUGS
With default field separation, the collating sequence is that of sort -b; with -t, the sequence is that of a plain sort.
The conventions of join, sort, comm, uniq, look and awk(1) are wildly incongruous.
