Full Discussion: Simple conditional yields too many responses
Top Forums UNIX for Beginners Questions & Answers Simple conditional yields too many responses Post 303030477 by Xubuntu56 on Monday 11th of February 2019 11:45:22 AM

@joeyg--I wanted a single response, either "Yes, that is a bird." or "That is not a bird."
@vbe--I tried something else, but unfortunately it appears I need a stronger hint! Now, it works correctly for "duck", but does nothing for the other two birds, nor does it do anything for an incorrect response.
Code:
#!/bin/bash
# bird
read -rp "Enter name of a bird   "
REPLY=$REPLY
birdname="duck sparrow hawk"

for i in $birdname
do
     if [[ "$REPLY" = "$i" ]]; then
             echo "Yes, that is a bird."
     fi
     exit
     if [[ ! "$REPLY" = "$i" ]]; then
         echo "That is not a bird."
      fi
done

results:

Code:
:~/bin$ bird
Enter name of a bird   duck
 Yes, that is a bird.


:~/bin$ bird
 Enter name of a bird   sparrow
:~/bin$ 


:~/bin$ bird
  Enter name of a bird   hawk
:~/bin$ 


:~/bin$ bird
 Enter name of a bird    spaniel
:~/bin$

shells

shells(4)							   File Formats 							 shells(4)

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh,
       /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh,
       /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list.

       Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1).
