Downloading most recent file using curl

Question

I need to download most recent file based on the file creation time from the remote site using curl. How can I achieve it?

These are files in remote site

  user-producer-info-etl-2.0.0-20221213.111513-53-exec.jar
  user-producer-info-etl-2.0.0-20221212.111513-53-exec.jar
  user-producer-info-etl-2.0.0-20221214.111513-53-exec.jar
  user-producer-info-etl-2.0.0-20221215.111513-53-exec.jar

Above user-producer-info-etl-2.0.0-20221215.111513-53-exec.jar is the most recent file that I want to download? How can I achieve it?

Luckily for you, file names contains dates that are alphabetically sortable !

I don't know where you are so I'm guessing you have at least a shell and I propose this bash answer:

First get the last file name

readonly endpoint="https://your-gitlab.local"

# Get the last filename
readonly most_recent_file="$(curl -s "${endpoint}/get_list_uri"|sort|tail -n 1)"

# Download it
curl -LOs curl "${endpoint}/get/${most_recent_file}"

You will obviously need to replace urls accordingly but I'm sure you get the idea

• -L : follow HTTP 302 redirects
• -O : download file to local dir keeping the name as is
• -s : silent don't show network times and stuff

you can also specify another local name with -o <the_most_recent_file>
