How do you ask, "Are you sure?"? 2

[mwesticle]

I have a Korn Shell script that works based on one input parameter. The user passes one string value to the script from the command line, like this:

script.ksh <string>

The script will list all files that match that string.
Then it will move files that contain that string into a directory for later archival. Example:

script.ksh *test*

will output this to the screen:

test.txt
test1.txt
job1.test

Then it will move those files to another directory.

MY QUESTION: HOW CAN I GET THE SCRIPT TO ASK THE USER IF THEY'RE SURE THEY WANT TO DO THIS, AFTER SEEING THE FILES THAT WILL BE MOVED? Currently, it just shows the list and moves the files. I need the user to verify the list is correct before moving on, or stop if the list is incorrect. I'd like the user to just have to type 'Y' or 'N'. Is there a way to do this in a Korn Shell Script? Any help would be awesome! Thanks!

Try something like this :

[tt]
# List files to move

echo &quot;Files to move :&quot;
for file
do
echo $file
done

# ask for confirmation

typeset -u Confirm
until [[ &quot;$Confirm&quot; = [YN] ]]
do
read Confirm?&quot;Are you sure [Y/N] ? &quot;
done

# Moves not confirmed

[ &quot;$Confirm&quot; = &quot;N&quot; ] && exit

# Files can be moved

for file
do
mv $file Save_Dir/
done
[/tt]

Hi:

Here's a ckyorn replacement:

if ! type ckyorn > /dev/null
then
# this function emulates the Solaris internal ckyorn function.
# optional parameters:
# d - default value
# p - user prompt
# Q - disable q for quit
# return: Y, y, N, N and q, Q if Q option is not disabled.
function ckyorn {
typeset option=
typeset default=
typeset prompt=
typeset REPLY=
typeset UREPLY=
typeset Q=Qq

while getopts :d:Q option
do
case $option
in
d) default=$OPTARG ;;
p) prompt=$OPTARG ;;
Q) typeset Q=&quot;&quot; ;;
esac
done

while echo &quot;$prompt\c&quot; 1>&2
do
read REPLY
UREPLY=$REPLY
case &quot;${UREPLY:=$default}&quot;
in
[ynYN$Q]*) break ;;
*) echo &quot;ERROR: Please enter yes or no.&quot; 1>&2 ;;
esac
done

echo &quot;$UREPLY&quot;
}
fi

#example
default=y
prompt=&quot;Continue (y/n)? [$default]:&quot;
answer=$(ckyorn -Q -p &quot;$prompt&quot; -d &quot;$default&quot
