Shell Programming and Scripting

Folks,

I have peculiar kind of error. my script goes like

cat inputfile> while read param
do
Array[$i]=$param
y=`expr $y + 1`
done

When i run script passing very large input file. script abends in the middle of execution saying "ksh: script out of range"
Possible reason is max array element size is 4095 which is exceeded in my case. Now my question, is there any settings in shell which i can use to increase the max array element size.


Guys please post ur suggestions.


Thanks!

It could be something related to shell's limits, though, the script seems to be incomplete, isn't it?
Perhaps it should be something like:

Code:

i=1
while read param; do
   Array[$i]=$param
   i=$(expr $i + 1)
done < inputfile

THanks for ur reply.


Part of the script was only posted there..

the real problem is when array element exceeds 4095 range.. script fails..
eg:
cat inputfile| while read param
do
array[$i]=$param
echo "array[$i]" array[$i]
done

Output:-

array[1]=line1
array[2]=line2
array[3]=line3
.
.
.
.
array[4095]=line
ksh: script out of range

so after element count crosses 4095 range script fails.


any ways to increase this max size limit

Thanks!

I had to ask
Exactly, there is a limit in ksh. What I do not know yet is if it is possible to increase that number.
Otherwise, you could use bash, whose limit (at least on my OS/version) is much higher.

hey dude..


y dont u try using bash shell!

He may not have it on his box..... there are other unix systems that do not have bash out of the box, and it requires root access to install GNU goodies. IF one exists for his box.

Sorry guys, i had to use only ksh .. any other possible ways..

Thanks,
