Linux 서버 설정에서 echo 문을 파일로 리디렉션할 수 있습니까?

나는 bash 스크립팅을 처음 접한다는 점부터 시작하겠습니다. 저는 "kiltslog.txt"라는 텍스트 파일에 기록되는 콘텐츠를 네트워크의 다른 디렉터리로 리디렉션하는 작업을 맡았습니다. 참고: 다음 스크립트는 작성하지 않았습니다. 10분마다 실행됩니다... 위의 로그 파일이 다음 스크립트에서 어떻게 생성/업데이트되는지 전혀 모릅니다. 한 가지 더... "kiltslog.txt" 파일은 10분마다 업데이트되며 "echo StartExec:"로 시작하는 모든 "echo" 문은 위의 로그 파일에 기록됩니다. 또한 스크립트 어디에도 "kiltslog.txt" 파일에 대한 참조가 없습니다.

#!/bin/bash

start_ts=`date +%s`
out_date=$(date -d @$start_ts --rfc-3339 ns)
echo StartExec: $out_date $start_ts

# min free space, in KB
# equal to 4TB
minSpaceThreshold=4294967296
echo "Checking free space..."

myUsed=$(df -k /nielsen_extracts  | tail -1 | awk '{print $3}')

## this can be collapsed into one awk function here:
df -k /nielsen_extracts  | tail -1 | /bin/awk '{if  (int ($3)>4294967296) print "Enough space: " $3;else print "Not enough space " $3 }'

if [[ $myUsed -gt $minSpaceThreshold ]] ;
then
        echo "We have enough free space:" $myUsed
else
        echo "We do not have enough free space:" $myUsed
        exit
fi
