I need to capture multiple values from user input and do not know how to do it. I'm writing a script to delete old files, but want to give the option to keep some by asking the user.
This is what my output looks like...
Old files to be deleted...
1 file1
2 file2
Then this bit of code is run after the above is output to keep or delete files.
echo "Would you like to keep any found files? (y/n)"
read USER_ANSWER
while [ ${USER_ANSWER} == "y" ]
do
echo "Type the number associated with the file(s) to be kept."
read USER_NUM
if [ $USER_NUM -gt ${#FILES[@]} -o $USER_NUM -le 0 ]
then
echo -e "Invalid."
else
echo -e "\nKeeping: " ${FILEST[${USER_NUM}]}"\n"
touch ${FILES[${USER_NUM}]}
echo -e "Removing "${FILES[@]}
break
fi
done
if [ ${USER_ANSWER} == "n" ]
then
echo -e "\nDeleting "${FILES[@]}
rm -r ${FILES[@]}
fi
And from this point I prompt the user and ask which files they want to keep if any, and they select a number from the above output and it keeps that file. But I want to make it so the user can input more than one number for keeping the files, like typing 1 2 3 4 if they want to keep those four files.
How do I do this? I'm new to bash the more explanation contained in the answer the more I can learn
I don't typically write in bash so there are probably a lot of errors but if you could help me with the multiple variable user input that would help!
