Download Jira Cloud Attachments into directories named after issue keys

downloadbykey.sh

#!/bin/bash
# Minor update to https://bitbucket.org/snippets/atlassiansupportprojects/nedyBb/download-files-attached-to-the-issues
# * Gets issue key in addition to download URL
# * Downloads attachments into directories created for each issue key
#
# Usage:
#   chmod u+x ./downloadbykey.sh
#   bash ./downloadbykey.sh

# 1. Issue your API Token at https://id.atlassian.com/manage/api-tokens
# 2. Install "jq" command and add it to your bash's PATH https://stedolan.github.io/jq/
# 3. Modify the JQL below
# 4. Hardcode your email@example.com:API_TOKEN into the xargs down at the bottom because I couldn't figure out the shell quoting

HOST="example.atlassian.net"
USER="email@example.com"
API_TOKEN="__YOURS_HERE__"

USERARG="$USER:$API_TOKEN"

# https://developer.atlassian.com/cloud/jira/platform/rest/#api-api-2-search-post

curl -sL --request POST \
  --user "${USER}:${API_TOKEN}" \
  --header 'Accept: application/json' \
  --header 'Content-Type: application/json' \
  --url "https://${HOST}/rest/api/2/search" \
  --data '{
    "jql": "project = SK AND NOT attachments is EMPTY",
    "startAt": 0,
    "maxResults": 100,
    "fields": ["attachment"],
    "fieldsByKeys": false
  }' \
| jq -r '.issues[] | {key,content:.fields.attachment[].content} | [.key, .content] | join(" ") ' \
| xargs -n2 sh -c 'curl -L --create-dirs --user email@example.com:API_TOKEN --url $2 --output $1/$(basename $2)' sh

Thanks for this! I forked it with the main purpose of saving the attachments with their original filenames. Additionally, I didn't find hard-coding the user and API token in the xargs invocation to be necessary in my usage, just passed in those variable names.
