RedHat Need Menu option each on a new line

Here is my script for the menu options.
# Bash Menu Script Example

PS3='Please enter your choice: '
options=("Option 1:" "Option 2:" "Other Reason:" "Quit")
select opt in "${options[@]}"
    case $opt in
        "Option 1 :")
            echo "you chose choice 1"
        "Option 2:")
            echo "you chose choice 2"
        "Other Reason:")
            echo "you chose choice 3"
        *) echo invalid option;;

When i run the script i see the output as below.

1) Option 1: 3) Other Reason:
2) Option 2: 4) Quit
when i need it to look like

1) Option 1:
2) Option 2:
3) Other Reason:
4) Quit
Can you let me know what needs to be done.

Does this help:
man bash:
Used by the select compound command to determine the terminal width when printing selection lists. Automatically set if the checkwinsize option is enabled or in an interactive shell upon receipt of a SIGWINCH.

Interesting! I was not aware of this - but I found that this behaved differently in my bash (4.3.42(4)-release): First, I verified that a SIGWINCH indeed sets COLUMNS correctly (in my case to 92, which corresponds to the width of my mintty terminal). Then I entered the command exactly like the OP provided - but the menu still occurs for me in a single column.

I wonder whether some other setting also affects this behaviour. select also uses the LINES variable, but even with setting LINES to a ridiculously low value (2), I could not get a multi-column display.

And it also worked for me as well.

My system:
OS, ker|rel, machine: Linux, 3.16.0-4-amd64, x86_64
Distribution        : Debian 8.6 (jessie)
bash GNU bash 4.3.30

The characteristics of this terminal::
$ stty -a 
speed 38400 baud; rows 24; columns 80; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R;
werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0;
-parenb -parodd -cmspar cs8 -hupcl -cstopb cread -clocal -crtscts
-ignbrk -brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr icrnl ixon ixoff
-iuclc -ixany -imaxbel -iutf8
opost -olcuc -ocrnl onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0 bs0 vt0 ff0
isig icanon iexten echo echoe echok -echonl -noflsh -xcase -tostop -echoprt
echoctl echoke

After changing my environment with export COLUMNS=50 the menu was displayed in 2 columns.

@mohtashims -- omitting details of your environment means that we often may need to guess at answers. I think that with more than 500 posts that would become almost automatic for you.

Good luck ... cheers, drl
