Linux体系高能够运用history号令去查看指令的汗青记载。为了进步history号令的效力,借能够正在history号令添上一些参数,好比工夫、用户战IP等等参数。这么若何正在history上加添那些参数呢?
1.配置显现工夫战用户:
echo ‘export HISTTIMEFORMAT=“%F %T `whoami` ”’ 》》 /etc/profile
执止source熟效:
source /etc/profile
查看成果:
history
1852 2016-01-11 16:24:52 xubo hs
1853 2016-01-11 16:24:53 xubo ls
1854 2016-01-11 16:24:56 xubo history
1855 2016-01-11 16:25:02 xubo history --help
1856 2016-01-11 16:26:35 xubo vi /etc/profile
1857 2016-01-11 16:27:27 xubo echo ‘export HISTTIMEFORMAT=“%F %T `whoami` ”’ 》》 /etc/profile
1858 2016-01-11 16:27:29 xubo vi /etc/profile
1859 2016-01-11 16:27:42 xubo source /etc/profile
1860 2016-01-11 16:27:46 xubo history
1861 2016-01-11 16:27:59 xubo ls
1862 2016-01-11 16:28:01 xubo history
1863 2016-01-11 16:31:00 xubo clear
1864 2016-01-11 16:31:02 xubo history
2.只看到本人的操做记载(工夫,用户,ip名):
USER_IP=`who -u am i 2》/dev/null| awk ‘{print $NF}’|sed -e ‘s/[()]//g’`
xport HISTTIMEFORMAT=“[%F %T][`whoami`][${USER_IP}] ”
执止source熟效:
source /etc/profile
查看成果:
hadoop@Master:~$ history
1002 [2016-01-11 16:47:37][hadoop][host-e-150.ustcsz.edu.cn] cd 。。/
1003 [2016-01-11 16:47:37][hadoop][host-e-150.ustcsz.edu.cn] du -h --max-depth=1
1004 [2016-01-11 16:47:37][hadoop][host-e-150.ustcsz.edu.cn] du -h --max-depth=2
1005 [2016-01-11 16:47:37][hadoop][host-e-150.ustcsz.edu.cn] sudo find /* -name pokec-relationships
1006 [2016-01-11 16:47:37][hadoop][host-e-150.ustcsz.edu.cn] sudo find /* -name pokec
1007 [2016-01-11 16:47:37][hadoop][host-e-150.ustcsz.edu.cn] sudo find /* -name kddcup
1008 [2016-01-11 16:47:37][hadoop][host-e-150.ustcsz.edu.cn] sudo find /* -name kddcup*
1009 [2016-01-11 16:47:37][hadoop][host-e-150.ustcsz.edu.cn] sudo find /* -name *kddcup*
3.将history记载到log:
#export HISTTIMEFORMAT=“%F %T $USER_IP:`whoami` ”
#export HISTTIMEFORMAT=“%F %T $USER_IP:`whoami` ”
USER_IP=`who -u am i 2》/dev/null| awk ‘{print $NF}’|sed -e ‘s/[()]//g’`
export HISTTIMEFORMAT=“[%F %T][`whoami`][${USER_IP}] ”
#history
LOGIP=`who -u am i 2》/dev/null| awk ‘{print $NF}’|sed -e ‘s/[()]//g’`
LOG_DIR=/var/log/history
if [ -z $LOGIP ]
then
LOGIP=`hostname`
fi
if [ ! -d $LOG_DIR ]
then
mkdir -p $LOG_DIR
chmod 777 $LOG_DIR
fi
if [ ! -d $LOG_DIR/${LOGNAME} ]
then
mkdir -p $LOG_DIR/${LOGNAME}
chmod 777 $LOG_DIR/${LOGNAME}
fi
export HISTSIZE=4096
LOGTM=`date +“%Y%m%d_%H%M%S”`
export HISTFILE=“$LOG_DIR/${LOGNAME}/${LOGIP}-$LOGTM”
chmod 777 $LOG_DIR/${LOGNAME}/*-* 2》/dev/null
运转成果:
root@xubo:/media/xubo/My Passport/gene_data/1000genomes# ls /var/log/history/root/
host-e-150.ustcsz.edu.cn-20160111_171845 host-e-150.ustcsz.edu.cn-20160111_172719 host-e-213.ustcsz.edu.cn-20160111_202047
root@xubo:/media/xubo/My Passport/gene_data/1000genomes# vi /var/log/history/root/host-e-213.ustcsz.edu.cn-20160111_202047
#1452514808
ls root/
#1452514818
history
#1452514847
source /etc/profile
#1452514848
history
#1452514860
ls root/
#1452514861
ls
#1452514863
cd root/
#1452514864
ls
#1452514866
exit
以上便是Linux若何正在history上加添工夫战用户等参数的要领了,那样一去便能让history查阅号令时显现工夫战用户的那些参数,查找愈加粗准。
