Getopts not echoing correctly

Hi,

When I run the the following code:

Code:

#!/bin/bash


if [[ ${#} -lt 1 ]]; then
    usage
fi

if [[ ${UID}  -eq 0 ]]
then
echo "Do not execute this as root, use -s instead"
fi

SERVERFILE="servers"

function usage {
    echo "USAGE: ${0} [-nsv] [-f FILE] COMMAND"
    echo "-f FILE   Use to override the default file"
    echo "-n        Use for dry Run"
    echo "-s        Use to run the command with sudo"
    echo "-v        Use for verbose"
}




#ssh -o ConnectTimeout=2 server01 sudo 

while getopts 'nsvf:' opt
do
    case "${opt}" in
        n)
            shift "$((OPTIND-1))"
            COMMANDS="${*}"
            cat ${SERVERFILE} | while read line 

                do
                echo "DRY RUN ssh -o ConnectTimeout=2 ${line} ${COMMANDS}"
                done
            
            exit 0

        ;;

        s)
            AS_SUDO="YES"
                                  
        ;;

         f)
            
            SERVERFILE=${OPTARG}
        ;;

        v)
            
            echo "verbose mode"
        ;;

    esac
    done
shift "$((OPTIND-1))"

I get the following output:

Code:

[vagrant@admin01 vagrant]$ ./new-script.sh -n test-command
 test-commando ConnectTimeout=2 10.9.8.11
 test-commando ConnectTimeout=2 10.9.8.12

I am not sure why is that. Any help will be appreciated.

echo

echo(1B)					     SunOS/BSD Compatibility Package Commands						  echo(1B)

NAME

       echo - echo arguments to standard output

SYNOPSIS

       /usr/ucb/echo [-n] [argument]

DESCRIPTION

       echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output.

       echo  is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi-
       ronment variables.

       For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows:

	 o  echo your current-working-directory's full pathname

	 o  pipe the output through tr to translate the path's embedded slash-characters into space-characters

	 o  pipe that output through wc -w for a count of the names in your path.

	      example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w"

       See tr(1) and wc(1) for their functionality.

       The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be  invoked	if
       the  user  calls  echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape
       characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the  black-slashed  escape  characters,	and  ksh's
       echo() also understands a as the audible bell character; however, these commands do not have an -n option.

OPTIONS

       -n	Do not add the NEWLINE to the output.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWscpu			   |
       +-----------------------------+-----------------------------+

SEE ALSO

       csh(1), echo(1), ksh(1), sh(1), tr(1),  wc(1), attributes(5)

NOTES

       The -n option is a transition aid for BSD applications, and may not be supported in future  releases.
