# 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'.

# 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:
#        - Enforced proper credential formatting: credentials must be in the username:password format.
#        - Fixed help message shows script name without hard code it.
# v1.2.1 - 2025-02-26 SUPSCR-209: Auto detect CSN or SCS to adjust castor.log file 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 - 2025-02-27 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.
# v1.3.2 - 2025-03-02 Minor bug fix and enhancement.
# v1.3.3 - 2025-03-02 Fixed tmux command to long issue.
# --v1.3.4 - Enhanced password handling to better support password with special characters.
