Hi.

Using a shell array:

Code:

#!/usr/bin/env sh

# @(#) s2       Demonstrate saving file in array, processing based on index.

set -o nounset
echo

debug=":"
debug="echo"

## The shebang using "env" line is designed for portability. For
#  higher security, use:
#
#  #!/bin/sh -

## Use local command version for the commands in this demonstration.

echo "(Versions displayed with local utility \"version\")"
version >/dev/null 2>&1 && version bash

echo

FILE1=${1-data1}
echo " Input file $FILE1:"
cat $FILE1

echo
FILE2=${1-data2}
echo " Input file $FILE2:"
cat $FILE2

echo
echo " Results from processing:"

while IFS=":" read a b
do
  content[$a]="$b"
done <$FILE1

while read a
do
  echo ${content[$a]}
done <$FILE2

exit 0

Producing:

Code:

% ./s2

(Versions displayed with local utility "version")
GNU bash 2.05b.0

 Input file data1:
5:John
4:Michel
9:Rachel
100:George

 Input file data2:
9
100
4
5
5
4
9
100
100

 Results from processing:
Rachel

NAME

       echo, noecho - enable/disable terminal echo

SYNOPSIS

       cc [ flag... ] file... -I /usr/xpg4/include  -L	/usr/xpg4/lib 
	-R  /usr/xpg4/lib  -lcurses  [ library... ]

       c89 [ flag... ] file... -lcurses [ library... ]

       int echo(void);

DESCRIPTION

       The  echo()  function enables Echo mode for the current screen. The noecho() function disables Echo mode for the current screen. Initially,
       curses software echo mode is enabled and hardware echo mode of the tty driver is disabled. The echo() and noecho() functions control  soft-
       ware echo only. Hardware echo must remain disabled for the duration of the application, else the behavior is undefined.

RETURN VALUES

       Upon successful completion, these functions return OK. Otherwise, they return ERR.

ERRORS

       No errors are defined.
