How To Print Array in awk?
Hello,

May i please know how do i print the array using awk script. I am using below shell script to start with but not working.

Code:
#!/bin/bash

LOADSTATUS[0]="Line 0"
LOADSTATUS[1]="Line 1"
LOADSTATUS[2]="Line 2"
LOADSTATUS[3]="Line 3"
LOADSTATUS[4]="Line 4"

awk '
BEGIN {
Your File Load Status
}
{
for (x = 1; x <= max; x++)
print LOADSTATUS[x]
}'


Thanks,
Sampath.

It's a bash variable, not an awk one -- they're separate languages.

You'd want to actually put it into awk for it to be able to print it.

Code:
OLDIFS="$IFS" # Save value of special variable
IFS="|"

awk -v AS="${LOADSTATUS[*]}" 'BEGIN { MAX=split(AS,LOADSTATUS,"|");
for (x = 1; x <= MAX; x++)
        print LOADSTATUS[x]
 }' /dev/null

IFS="$OLDIFS"

The IFS variable controls, among other things, what string it will put between array members when you do ${ARRAY[*]}. Here we tell it to use | so awk can split it back apart into an array.
