Read textfile and enter the values in array

luna_soleil · #1 (**permalink**) 02-25-2009

Hi,

I want to put values in .txt file into array. Example :

$vi repo.txt
abc
def
ghi
jkl
mno
pqr

i want the output to be like this:
$echo ${mydf[1]}
abc
$echo ${mydf[2]}
def
$echo ${mydf[3]}
ghi
$echo ${mydf[4]}
jkl
$echo ${mydf[5]}
mno
$echo ${mydf[6]}
pqr

my script:
for i in 1 2 3 4 5 6
do
read mydf[$i] < repo.txt
print "mydf[$i] value is ${mydf[i]}"
done

What's wrong with my script? cuz anytime I echo ${mydf[1]}, I got empty output.. not abc...

Please helppp

Thanks

Hi cfajohnson,

I do not have problem on print "mydf[$i] value is ${mydf[i]}" as I get the correct output but I have problem when trying to echo the value of ${mydf[1]} on the command prompt after running this script. Any tips?

A script cannot affect the environment of the calling shell unless it is sourced:

Code:
. script-name
