Comparing 2 words
Hi

I have assigned list of arrays as below:
rtab[1]="TAB1 Y"
rtab[2]="TAB2 Y"
rtab[3]="TAB3 Y"
rtab[4]="TAB4 Y"

And I have a text file comp.txt that contains
>vi comp.txt
TAB1 Y
TAB2 Y
TAB3 Y
TAB4 Y

I want to compare the content of the array with the content in comp.tx.. so I have written the code as below :

i=0
while read ttab
do
arr[$((i=i+1))]=$ttab
if [ $ttab = ${rtab[i]} ]
then
echo "${rtab[i]} -> status is Y [PASS]"
else
echo "${rtab[i]} -> status is N [FAIL]"
fi
done < comp.txt

But unfortunately I've been getting output ..status is N [FAIL] everytime i run this script.
Is this because the script can't compare 2 words TAB Y ("TAB2 Y" compare with "TAB2 Y" is not permitted, "TAB" compare with "TAB" is OK)?
If yes, how do I rectify this?

Thank u very much Smilie

arrays start the index from zero not one.

If you want to prove existence of one of the array elements in the file comp.txt
using grep:
Code:
grep -q -e "${rtab[1]}"  -e "${rtab[2]}" -e "${rtab[3]}" -e "${rtab[4]}" -e "${rtab[4]}" comp.txt
if [[ $? -eq 0 ]] ; then
  echo "found"
else
  echo "not found"
fi

Quote the variables in this statement:

Code:
if [ "$ttab" = "${rtab[i]}" ]
