[work] 如何周期性写入文件

Watch is designed to run in a console window. Printing its output to file is inconvenient, because of the extensive amount of unprintable formatting characters.

You can try this without watch, if the exact 60 seconds is not an issue:

 while <some condition>
 do
     <mycommand> 2>&1 | tee -a /path/to/logfile
     sleep 60
 done

This saves the output to a log file and shows it on console as well.

#!/bin/bash

print_accuracy() {
	echo multi_gpus
	cat multi_gpus/slurm* | grep '* Prec@1'
	echo -e "\n"

	echo multi_gpus2
	cat multi_gpus2/slurm* | grep '* Prec@1'
	echo -e "\n"

	echo multi_gpus3
	cat multi_gpus3/slurm* | grep '* Prec@1'
	echo -e "\n"

	echo multi_gpus4
	cat multi_gpus4/slurm* | grep '* Prec@1'
	echo -e "\n"

	echo multi_gpus5
	cat multi_gpus5/slurm* | grep '* Prec@1'
	echo -e "\n"

	echo multi_gpus6
	cat multi_gpus6/slurm* | grep '* Prec@1'
	echo -e "\n"
}

while true
 do
     print_accuracy 2>&1 | tee log.log
     sleep 5
 done
