Array bash script doesn't work

Question

#!/bin/bash
ARRAYNAME=( 'time1' 'life' 'time2' )
echo ${ARRAYNAME[1]}

In the above code when i run my script as

$ sh ex1.sh

it gives an error message:

ex1.sh: 2: Syntax error: "(" unexpected

Why is this?

Run bash ex1.sh when you want to use bash features (not found in the POSIX shell). — Jonathan Leffler

sh on your system is not bash.

Exactly. The #!/bin/bash says to run the script using /bin/bash, but by running it with sh ex1.sh, you ignore that and run it using sh. Just run it as ./ex1.sh. (And the .sh suffix isn't really needed.)

Your "shebang" lines uses bash shell ("/bin/bash") but you're probably invoking another shell ("sh") invoking another shell to execute your script. Try this :

$ chmod 700 ex1.sh

This will make your script executable. Then run it :

$ ./ex1.sh
