Looks good. You can streamline the no echo of the password by passing read an -s flag. I’ve also updated it to allow for a -u or —user flag:
#!/bin/bash USERNAME= PASSWORD= DRILL_VER=drill-1.4.0 DRILL_LOC=/opt/mapr/drill URL=jdbc:drill:zk=10.10.15.10:5181,10.10.15.11:5181,10.10.15.12:5181/drill/se1-drillbits DPROP=~/prop$$ touch $DPROP chmod 600 $DPROP usage () { echo "$0 [ -u|--user username ]" } ask_user () { read -p "Enter username: " USERNAME } ask_pass () { read -s -p "Enter password for ${USERNAME}: " PASSWORD echo "" } while :; do case $1 in -h|-\?|--help) usage exit ;; -u|--user) if [ -n "$2" ]; then USERNAME=$2 shift else printf 'ERROR: "--user" requires a non-empty option argument.\n' >&2 exit 1 fi ;; --user=?*) USERNAME=${1#*=} # Delete everything up to "=" and assign the remainder. ;; --file=) # Handle the case of an empty --file= printf 'ERROR: "--user" requires a non-empty option argument.\n' >&2 exit 1 ;; --) # End of all options. shift break ;; -?*) printf 'WARN: Unknown option (ignored): %s\n' "$1" >&2 ;; *) # Default case: If no more options then break out of the loop. break esac shiftdone if [[ -z $USERNAME ]];then ask_userfi if [[ -z $PASSWORD ]];then ask_passfi # Write properties file for Drill cat >> $DPROP <<! user=$USERNAME password=$PASSWORD url=$URL ! # Exectue Drill connect with properties file. After 5 seconds, the command# will delete the prop file. Note this may result in race condition.# 5 seconds SHOULD be enough. (sleep 5; rm $DPROP) & $DRILL_LOC/$DRILL_VER/bin/sqlline $DPROP I stuck this up on a public gist if anyone else wants to fiddle with it: https://gist.github.com/cjmatta/93993f9283c3508c18d6 Chris Matta cma...@mapr.com 215-701-3146 On Thu, Feb 4, 2016 at 9:31 AM, John Omernik <j...@omernik.com> wrote: > That works, here is the script I came up with (mostly based on Ted's script > with a few terminal reads).
