# Script: castor-change-log-level.sh
# -----------------------------------------------------------------------------------------------------------------------------
# Description:
# This script changes the log level for the Castor cluster or node(s) using the Swarm API.
# The script supports changing the log level for the entire cluster or individual node(s).
# The script can run in a detachable session using 'screen' or 'tmux'.

# Written by Milton Suen (milton.suen@datacore.com) Oct 31, 2024
# Revision History:
# v1.0.0 - Update to support running the script in a detachable session using screen or tmux.
# v1.1.0 - 2025-02-20 Add support node(s) level log level change.
# v1.2.0 - 2025-02-26 SUPSCR-208: Auto detect CSN or SCS to adjust castor.log file path
#        - Enforced proper credential formatting: credentials must be in the username:password format.
# v1.2.1 - 2025-02-26 Address the issue of the- scriptFixed nothelp displaymessage correctshows whenscript thename castor.logwithout filehard iscode rotatedit.
# v1.2.21 - 2025-02-26 SUPSCR-209: EnforcedAuto properdetect credentialCSN formatting:or credentialsSCS mustto beadjust incastor.log the username:password formatfile path.
# v1.2.2 - 2025-02-27 Address the issue of the script not display correct when the castor.log file is rotated.
# v1.2.3 - 2025-02-27 Address the issue of log level not display correct within detach session.
# v1.2.4 - 2025-02---------------------------------------------------------------------------------------------------------------------
# Current Version: 1.2.2
# -----------------------27 Bug fix: The default node-level log level is 0 (unset), which differs from the cluster-level default of 30.
# v1.2.5 - 2025-02-28 SUPSCR-208:
#        - Credentials validation and password prompt enhancements.
#        - screen or tmux required with detachable mode, script will stopped with '-D' option if neither is installed.
#        - Fixed an issue where users were prompted to enter password multiple times issue.
#        - Passwords are now hidden in debug output messages.
# v1.2.6 - 2025-02-28 SUPSCR-208:
#        - Disabled credential display on the screen.
#        - Bug fix: Resolved the "debug: command not found" error when removing the -d [IP address] option.
# v1.3.0 - 2025-02-28 minor bug fix and enhancement.
# v1.3.1 - 2025-03-01 SUPSCR-208:
#        - Fixed an issue where credentials enclosed in single quotes (') were not processed correctly.
