Inserting elements into array in ksh

Question

I am trying to insert dynamic elements to Any array after reading from a file. I am using ksh & i am getting error.

cat /user/may/onlySysVols

DATA4
DATA5
OSS90
SYSTEM
AUDIT
DATA1
DATA2
DATA3

cat tst.sh

 1. i=0
 2. grep -Ev "OSS|SYSTEM|AUDIT|VD|LAKE|$escvol" /user/may/onlySysVols |\
 3.   while read lin
 4.   do
 5.     eval ${sysVolArray}'[$i]'="\$lin"
 6.     ((i+=1))
 7.   done
 8.
 9.   echo "${sysVolArray[*]}"

Output:

./tst.sh[5]: [0]=$DATA1:  not found
./tst.sh[5]: [1]=$DATA2:  not found
./tst.sh[5]: [2]=$DATA3:  not found
./tst.sh[5]: [3]=$DATA4:  not found
./tst.sh[5]: [4]=$DATA5:  not found

Desired O/P(Printing an array)

DATA1 DATA2 DATA3 DATA4 DATA5

Answer 1

我知道了：它在第5行中应该是eval sysVolArray [$ i] =“ \\ $ lin”（没有$ {sysVolArray}）

Answer 2

您可以使它更简单

sysVolArray=( $(grep -Ev "OSS|SYSTEM|AUDIT|VD|LAKE|$escvol" /usr/may/onlySysVols) )
