This should solve your problem -- change the line
Code:
if $a=$c
to
Code:
if [ "$a" = "$c" ]

Tests need to be in square brackets '[]'

eg.
if [ $c = $a ]
then
# do something

fi

I usually put strings in double quotes and leave numbers bare

eg
STRING1="some garbage"
if [ "$STRING1" = "hello" ] ....

COUNT=5
if [ $COUNT -eq 7 ] ...

Please note there are different types of tests depending on the data types, here's a reference:

cheers

Double brackets [[ ]] is more robust http://tldp.org/LDP/abs/html/testcon...ml#DBLBRACKETS

What kpb wrote except [[ ]] is preferred for testing over [ ].
