Array assignments must not have spaces after the "=", I suspect you have:
Code:
sqlfiles= ( "$HOME/HY_DUMP"/*.sql )

instead of:
Code:
sqlfiles=( "$HOME/HY_DUMP"/*.sql )

Also this:
Code:
# save and change IFS 
OLDIFS=$IFS 
IFS=$'\n' 
 # read all file name into an array 
fileArray=( $(ls -l) )   
# restore it 
IFS=$OLDIFS

and this:
Code:
IFS=$'\n' testarray=( $(ls -1) )

are the same (in the above syntax IFS is set for 1 statement and automatically restored by the shell)

Chubler,

i tried to remove the space between the = and still i had the same problem. Yes, the code line you gave is the same as the one i used in my script. Your code gave me an idea to use it.

Anyway, i end up with the same problem. There are syntax errors as i listed before.

I moved to another approach that i posted in the recent blog. I still have some problems but, it is better than my previous failed attempts.

Please look at it and let me know if you could tweek the problem in the latest script.

Appreciate your quick reply.

If your experiences in the other thread are any indication, you are not using the bash shell. These problems will remain, until you do.

Corona,

I reran the scripts using bash shell and they were throwing the same errors at me.

I am still looking for some help trying to print the values stored in the array for the code below:

Code:
#!/bin/bash
cd $HOME/HY_DUMP
num=0
for filename in *.sql
do 
testarray[$num]=$filename
(( num += 1 ))
echo $num
done
testnum=$num
num=0
echo $testnum

Any help with this, i would highly appreciate.

I suspect you still have spaces before the assignment as Chubler_XL noted.

Corona,

I dont get what you mean. I have run the latest script i posted just above your post. I was able to assign the file names to the array. I am not sure how to look at the values stored in the array.

I need some help trying to print the values in the array.

Hello All,

Here is the code i wrote to print the values assigned in the variable:

Code:
#!/usr/bin/env bash
cd $HOME/HY_DUMP
num=0
for filename in *.sql
do


testarray[$num]=$filename
#num=`expr $num + 1`
(( num += 1 ))
echo $num
#echo "new yo"
done
testnum=$num
num=0
echo $testnum
for filename in *.sql
do
echo ${testarray[$num]}
echo $num
(( num += 1))

done

And this is the output i am recieving:

[/output]

The wierdest thing with the output is some of the values are getting concatenated with the previous values.
Is there anyway to flush the value stored in filename after the value is being assigned to the array so that we could avoid this problem?
