Bash script - array of strings? -

i'm new bash script coding, i've put want reboot services on server (in case crash)

however, i'm hitting stumbling block @ basic point:

#!/bin/bash  declare -a arr=(tomcat7 nginx mysql);

...gives error:

script-checks.sh: 3: script-checks.sh: syntax error: "(" unexpected

i've tried quoted well:

declare -a arr=("tomcat7" "nginx" "mysql");

i don't understand why i'm getting error though. looks i'm using correct syntax:

please advise (i'm coming perl background, quite different me - appologies if i've missing stupid!)

your script not run bash. suppose uses sh.
