comparing multiple variables by 'if then'
Hi,
I am a noob at shell scripting.
basically I am trying to compare row counts from 8 tables in different databases. I have managed to get the row counts using awk from the spool files for both databases.
now I have 16 variables with me
for database 1 :
$A
$B
$C
$D
$E
$F
$G
$H
for database 2:
$A1
$B1
$C1
$D1
$E1
$F1
$G1
$H1
now i want to compare the row counts if they r equal....if so, the script shud continue and execute my next script say 'next.sh' lying in the same directory
else it shud give an error and mail to the user.
what i am trying to do is
if $A = $A1 and
$B = $B1
...
... and
$H=$H1
then
all 8 variables must be equal to each other before continuing else the script shud error out.
PLease help
