Loop over multiple arrays
Hi All
I need really really help with this :-

I have two files ( File1 , File 2) both files are output of two different scripts.

File1 usually has a list of names ( sometimes 3 names sometimes 5 sometimes more , depends about the output of the script)
File2 usually has a list of numbers (ages) (depends about how many names in File1)

So if File1 has 3 names , File2 will have 3 different ages.

For example ,

If file1 has

Code:
Jon
Kim
Lee


File2 will has

Code:
23
44
21

I am trying to have my output to be like this :-

Code:
Jon is 23 
Kim is 44
Lee is 21

my current out put is :-

Code:
Jon is 23
Jon is 44
Jon is 21
Kim is 23
Kim is 44
Kim is 21
Lee is 23
Lee is 44
Lee is 21

here is my script :-

Code:
for NM in `cat /tmp/File1 | cut -d'=' -f2 | sort -u`; do 
  for AG in `cat /tmp/File2 | cut -d'=' -f2 | sort -u`; do 
 
    echo -ne  "$NM is $AG)"  >> /tmp/Output 
 
  done 
done


Can someone please help!

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 specifed 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.
