# Program:
#       This script is a finger daemon of program ximeaImageRecorder and psdkProgram. It has three function:
#       1) ensure that the programs ximeaImagerRecorder and psdkProgram are runing; if not run the programs;
#       2) generate log file name based the local time and directory if not exist;
#       3) redirect the output of programs to file generated in (2);
# Usage:
#	1) crontab -e
#	2) */1 * * * * /home/pi/tc_ShellScripts/finger_daemon.sh
# History:
#       2021/07/13    Tangchao    First release
#       2022/06/24    Tangchao    Second release
