1. As this new monitor.log file will have all time entries and the cron job will execute every 5 sec, I think this will send the old error messages again and again.
2. Also i need to avoid the same erros to be send frequently if it is happening continiously.

Please help me.

1. the command ">my.log" will clean the log file each time. So you should not get old error messages.

2. [ $n1 -ge 1 ] can be used to adjust with your request, and the cronjob frequency can be adjusted , for example, every 10 minutes.

Code:
[ $n1 -ge 5 ]

0,10,20,30,40,50 * * * * monitor.sh

with above changes, you will check the log every 10 minutes, and if found more than 5 errors, send mail to you. Otherwise, keep quiet.

NAME
set_color - set_color - set the terminal color set_color - set the terminal color Synopsis set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR] Description Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple, cyan, white and normal. o -b, --background Set the background color o -c, --print-colors Prints a list of all valid color names o -h, --help Display help message and exit o -o, --bold Set bold or extra bright mode o -u, --underline Set underlined mode o -v, --version Display version and exit Calling set_color normal will set the terminal color to whatever is the default color of the terminal. Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey font color, while set_color --bold white will result in a white font color. Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator. set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of ncurses and recompile fish against it in order to fix this issue. Version 1.23.1 Sun Jan 8 2012 set_color(1)
