If preserving the order of lines in File 1 is important, this comes close to producing the output you requested:
Code:
awk '
BEGIN { # Set input and output field separators
FS = OFS = ":"
}
NR == 1 {
# Save 1st input file pathname (since we will overwrite it later)
f1name = FILENAME
}
NR == FNR {
# Gather data from 1st input file
d[++f1c] = $2 # Data to be saved.
l[$1] = f1c # Line # from 2nd file to be printed on Line # from
# 1st file.
next
}
FNR in l {
# Gather data from 2nd input file for any line specifeid in the 1st
# field in the 1st file.
o[l[FNR]] = $1
}
END { # Overwrite the 1st input file with data gathered from both input files.
for(i = 1; i <= f1c; i++)
print o[i], d[i] > f1name
}' "File "[12]
which, with the sample input files you provided, changes the contents of File 1to be:
Code:
xyz2: Apple
xyz1: Banana
xyz5: Pear
xyz7: Orange
Be sure that you have a backup copy of File 1 before trying this since this script overwrites it.
If you want to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk, /usr/xpg6/bin/awk, or nawk.

join
JOIN(1) General Commands Manual JOIN(1)NAME
join - relational database operator
SYNOPSIS
join [-an] [-e s] [-o list] [-tc] 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.
-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.
