Hi,

Thanks for workaround, Actually my requirement is to get values from line by line in a file and assign to variable, it is good that for each line if there is separate variable also, from the above idea provided.

That is

initially my file looks like this
Code:
111|22|33|44|55|aa|bb|cc
dd|ee|ff|gg|ii|jj|kk|ll|mm|nn|oo|pp
 
line1[0]=111
line1[1]=22
line1[2]=33
line1[3]=44
line1[4]=55
line1[5]=aa
line1[6]=bb
line1[7]=cc
 
line2[0]=dd
line2[1]=ee
line2[2]=ff
line2[3]=gg
line2[4]=ii
line2[5]=jj
line2[6]=kk
line2[7]=ll
line2[8]=mm
line2[9]=nn
line2[10]=oo
line2[11]=pp

I tried to fetch using the below script but, it is not getting in separate variable for each line instead , in single variable array has the entire file data.

script:
Code:
#!/usr/bin/ksh
IFS=$'\|'
I=0
for WORD in $(cat fs_mail.txt); do
WORDS[$I]=$WORD
echo "WORDS[$I]=$WORD"
I=$((I + 1))
done


but the output like :
Code:
WORDS[0]=111
WORDS[1]=22
WORDS[2]=33
WORDS[3]=44
WORDS[4]=55
WORDS[5]=aa
WORDS[6]=bb
WORDS[7]=cc
dd
WORDS[8]=ee
WORDS[9]=ff
WORDS[10]=gg
WORDS[11]=ii
WORDS[12]=jj
WORDS[13]=kk
WORDS[14]=ll
WORDS[15]=mm
WORDS[16]=nn
WORDS[17]=oo
WORDS[18]=pp

As Mr.RudiC provided snippet to get the number of values in the line using that how to make a loop to create each variable for each line.

Could anyone Please help me on this. I hope i have explained it correctly.

Thanks,
Regards,
karthikram
