Event logging to file and display to console | tee command is not able to log all info.
My intention is to log the output to a file as well as it should be displayed on the console > I have used tee ( tee -a ${filename} ) command for this purpose. This is working as expected for first few outputs, after some event loggin nothing is gettting logged in to the file but It is displaying on the console.
I can elaborate this.
Dashed line indicate the operation performing (code). Here in this example first two statements are displaying and logging into log file. But from third statement onwards nothing is getting logged in to the file, but is is displaying on the console. Is this because the command execution speed is more, execution is very quick.?
Thanks,
Sanoop

tee
TEE(1) User Commands TEE(1)NAME
tee - read from standard input and write to standard output and files
SYNOPSIS
tee [OPTION]... [FILE]...
DESCRIPTION
Copy standard input to each FILE, and also to standard output.
-a, --append
append to the given FILEs, do not overwrite
-i, --ignore-interrupts
ignore interrupt signals
-p diagnose errors writing to non pipes
--output-error[=MODE]
set behavior on write error. See MODE below
--help display this help and exit
--version
output version information and exit
MODE determines behavior with write errors on the outputs:
'warn' diagnose errors writing to any output
'warn-nopipe'
diagnose errors writing to any output not a pipe
'exit' exit on error writing to any output
'exit-nopipe'
exit on error writing to any output not a pipe
The default MODE for the -p option is 'warn-nopipe'. The default operation when --output-error is not specified, is to exit immediately on
error writing to a pipe, and diagnose errors writing to non pipe outputs.
