关于linux:Linux上清理oracle-listenerlog文件脚本

Linux上清理oracle listener.log文件脚本，配合crontab定时清理大于1000MB的listener.log

#!/bin/bash# This script is used to clean up Oracle Database listener.log on Linux# Please use the Oracle DB installation user(such as oracle) to execute the script# Originally written by Xander.Cui# Use two methods to obtain the absolute path of listener.log, only for detection.# 2. Obtain the standard listener.log file name# export listenerlog=$ORACLE_BASE/diag/tnslsnr/$(hostname)/listener/trace/listener.log# export listenerlogbak=$listenerlog-$DateMarksource ~/.bash_profileexport DateMark=$(date +'%Y%m%d')export DT=$(date +'%F %T')# Check if the log directory exists, create it if it does not existexport logdir=~/logexport checklog=$logdir/listenerlog_check.logif [ ! -d $logdir ]; then    mkdir -p $logdir    echo "    $DT Checked: Created $logdir    " >$checklogfi# 1.

应用命令增加定时工作

(crontab -l | grep -v check_listenerlog) | crontab(crontab -l ; echo "0 18 * * * bash ~/scripts/check_listenerlog.sh") | crontab
