Existe uma configuração de servidor Linux para redirecionar instruções de eco para um arquivo?

Question

Deixe-me começar por dizer que sou novo no bash scripting. Fui encarregado de tentar redirecionar o conteúdo que está sendo gravado em um arquivo de texto chamado "kiltslog.txt" para outro diretório em nossa rede. Nota: Eu não escrevi o script a seguir: e ele é executado a cada 10 minutos ... o que eu não sei é como o arquivo de log acima está sendo gerado / atualizado a partir do script a seguir (se houver). Só mais uma coisa ... o arquivo "kiltslog.txt" está sendo atualizado a cada 10 minutos e toda a instrução "echo" começando com "echo StartExec:" é gravada no arquivo de log acima. Além disso, não vejo referências ao arquivo "kiltslog.txt" em nenhum lugar do script.

#!/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


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



# Use a lockfile containing the pid of the running process
# If script crashes and leaves lockfile around, it will have a different pid so
# will not prevent script running again.
#
lf=/tmp/pidLockFileKiltsProd
# create empty lock file if none exists
cat /dev/null >> $lf
read lastPID < $lf
# if lastPID is not null and a process with that pid exists , exit
[ ! -z "$lastPID" -a -d /proc/$lastPID ] && exit
echo not running
# save my pid in the lock file
echo $$ > $lf

O script provavelmente tem sua saída padrão redirecionada para um arquivo:

thescript >/path/to/kiltslog.txt

Então você tem que mudar o que quer que seja (cron job ou else).
