1) name1 1.1.1.1 2) name2 2.2.2.2 3) name3 3.3.3.3 4) name4 4.4.4.4 please enter choice: 1 

i'm assuming bash, not sh.

the select command isn't used. problem you're having you're slurping whole lines in $options readarray, , select command doesn't provide way format or trim output.

one approach split array after reading it:

#!/usr/bin/env bash  declare -a opt_host=()   # initialize our arrays, make sure they're empty. declare -a opt_ip=()     # note associative arrays require bash version 4. readarray -t options < ./file.txt  in "${!options[@]}";   opt_host[$i]="${options[$i]%% *}"             # create array of names   opt_ip[${opt_host[$i]}]="${options[$i]#* }"   # map names ips done  ps3='please enter choice (q quit): ' select host in "${opt_host[@]}";   case "$host" in     "") break ;;  # fake; invalid entry makes $host=="", not "q".     *) ssh "${opt_ip[$host]}" ;;   esac done
