Reassign value to a string variable
hi to all,

i have a string variable that i want to reassign a new value in it through a script and i am having some trouble.
i write the following if statement:

Code:
if [ $checkupd!="lastupdate" ]
then
$checkupd="lastupdate = "
fi

in this statement i check if the variable checkupd contains the word "lastupdate". if it doesnt contain this word then i want to assign it as a value of this variable. when i run it i get the following error:
Code:
=lastupdate = : not found

do i have to assign it with different way?

thank you for your time

Should be:

Code:
if [ "$checkupd" != "lastupdate" ]
then
  checkupd="lastupdate = "
fi
