How do I set or create variables within my shell script or at command line under Linux and Unix like operating systems?
You can easily create and set variables within a script using the following syntax:
variable=value x=5 y=10 dest=/nas05/backup today="Monday"
value is assigned to given variable and value must be on right side of = (equal) sign. If value is not given, the variable is assigned the null string. In this example set shell variable called dest to /nas05/backup/full, enter:
To display the value of a variable called dest, enter:
printf "%s\n" dest
