I have created a simple bash script in ubuntu to backup my projects:

#!/bin/bash
save_backup_path=~/Downloads/my_backup
web_projects_path=~/Downloads/my_backup/projects
cd $web_projects_path || return
for f in *; do if [ -d "$f" ]; then echo "backup project $f"; tar -zcf $save_backup_path/"$f"-$(date +%d-%m-%Y).tar.gz --exclude="$f"/node_modules --exclude="$f"/vendor --exclude="$f"/storage/framework/views/*.php --exclude="$f"/public/uploaded "$f" fi
done

it will create a tar.gz for each folder (project name).

What I want is to create a menu and select which project I want to create backup ex: (1, 2, 3 ... or * for all)

I don't know how to handle the select and do the job

I have used this for storing all the projects names (folders names)

for f in *; do if [ -d "$f" ]; then readarray -t project_names < <(echo "$f") fi
done

but when listing the select

echo "Select project for backup:"
select choice in "${project_names[@]}"; do [[ -n $choice ]] || { echo "Invalid choice. Please try again." >&2; continue; } break
done

it shows only the last one (the last folder name).

How can I do this to list all projects and create the tar.gz for selected one or all if selected is *

*** UPDATE ****

#!/bin/bash
### backup the projects
save_backup_path=~/Downloads/my_backup
web_projects_path=~/Downloads/my_backup/projects
cd $web_projects_path || return
declare -a project_names
i=1
for d in */
do project_names[i++]="${d%/}"
done
echo "Select project for backup:"
select choice in "${project_names[@]}"; do [[ -n $choice ]] || { echo "Invalid choice. Please try again." >&2; continue; } break
done
echo "backup project $choice ..."
tar -zcf $save_backup_path/"$choice"-$(date +%d-%m-%Y).tar.gz --exclude="$choice"/node_modules --exclude="$choice"/vendor --exclude="$choice"/storage/framework/views/*.php --exclude="$choice"/public/uploaded "$choice"

I have created the selected with choices and now it works for the selected project only. How can I handle for all projects ? If the user select * to make them all (separately)

I figured out how to backup all projects. Adding * to the existing array

Here is the final version:

#!/bin/bash
save_backup_path=~/Downloads/my_backup
web_projects_path=~/Downloads/my_backup/projects
cd $web_projects_path || return
declare -a project_names
i=1
for d in */
do project_names[i++]="${d%/}"
done
project_names[i++]="*"
echo "Select project for backup:"
select choice in "${project_names[@]}"; do [[ -n $choice ]] || { echo "Invalid choice. Please try again." >&2; continue; } break
done
backup_project() { echo "backup project $1 ..." tar -zcf $save_backup_path/"$1"-$(date +%d-%m-%Y).tar.gz --exclude="$1"/node_modules --exclude="$1"/vendor --exclude="$1"/storage/framework/views/*.php --exclude="$1"/public/uploaded "$1"
}
if [ "$choice" == "*" ]; then unset project_names[-1] for project in "${project_names[@]}"; do backup_project "$project" done else backup_project "$choice"
fi
