Here is an example how you could cycle and compare array elements (example with integers) and print only those from array 1, which are not in array 2:
Somehow there is a blank line at the end. Didn't find where it comes from
Maybe other people have more efficient algorithm to do this which would be interessting for me too.
If you have 2 files with the lists of files you might want to compare, a grep -f file1 file2 or grep -vf file1 file2 might be more efficient than my example.

Hello,
Let's say that we have the two following arrays
@array1=
@array2=
Is there any easy way to compare these two arrays and print the values that exist in array1 and not in array2 and the values that exist in array2 and not in array1?

combine
COMBINE(1)COMBINE(1)NAME
combine - combine sets of lines from two files using boolean operations
SYNOPSIS
combine file1 and file2
combine file1 not file2
combine file1 or file2
combine file1 xor file2
_ file1 and file2 _
_ file1 not file2 _
_ file1 or file2 _
_ file1 xor file2 _
DESCRIPTION
combine combines the lines in two files. Depending on the boolean operation specified, the contents will be combined in different ways:
and Outputs lines that are in file1 if they are also present in file2.
not Outputs lines that are in file1 but not in file2.
or Outputs lines that are in file1 or file2.
xor Outputs lines that are in either file1 or file2, but not in both files.
"-" can be specified for either file to read stdin for that file.
The input files need not be sorted, and the lines are output in the order they occur in file1 (followed by the order they occur in file2
for the two "or" operations). Bear in mind that this means that the operations are not commutative; "a and b" will not necessarily be the
same as "b and a". To obtain commutative behavior sort and uniq the result.
Note that this program can be installed as "_" to allow for the syntactic sugar shown in the latter half of the synopsis (similar to the
test/[ command). It is not currently installed as "_" by default, but you can alias it to that if you like.
