Example:
check_prog hostname.com /bin/check_awesome -c 10 -w 13
check_remote -H $HOSTNAME -C "$ARGS" #To be expanded as check_remote -H hostname.com -C "/bin/check_awesome -c 10 -w 13" I hope the above makes sense. The arguments will change as I will be using this for about 20+ commands. Its a odd method of wrapping a program, but it's to work around a few issues with a few systems we are using here (gotta love code from the 70s).
The above could be written in Perl or Python, but Bash would be the preferred method.

To invoke a function, simply use the function name as a command. To pass parameters to the function, add space separated arguments like other commands. The passed parameters can be accessed inside the function using the standard positional variables i.e. $0, $1, $2, $3 etc.
If you want to pass command line arguments then you will have to define the main() function with two arguments. The first argument defines the number of command line arguments and the second argument is the list of command line arguments.
You can use shift
shift is a shell builtin that operates on the positional parameters. Each time you invoke shift, it "shifts" all the positional parameters down by one. $2 becomes $1, $3 becomes $2, $4 becomes $3, and so on
example:
$ function foo() { echo $@; shift; echo $@; } $ foo 1 2 3 1 2 3 2 3 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
