xml config lookup shell scripts

例如可以用下面的scripts來查dfs.replication的設定值為何 [root@master02.dev ~]>cat ~/tttt.sh #!/bin/bash SEARCHPATH="./" if [ -z "$1" ]; then SEARCHPATH="./" else SEARCHPATH="$1" fi for file in `find $SEARCHPATH -name "*xml"` do echo $file cat $file | awk -F "\n" 'BEGIN{a=-1}{if(a < 0) { match($1 , pattern , ar); if( RSTART > 0) a=range; } if( a > 0) { a--; print markhead,$1; } }' range=2 pattern='dfs.replication' markhead='#' done [root@master02.dev process]>cd [root@master02.dev ~]>cd /var/run/cloudera-scm-agent/process [root@master02.dev process]>~/tttt.sh ./12-mapreduce-TASKTRACKER/mapred-site.xml ./12-mapreduce-TASKTRACKER/core-site.xml ./12-mapreduce-TASKTRACKER/hdfs-site.xml # <name>dfs.replication</name> # <value>3</value> ./13-mapreduce-JOBTRACKER/mapred-queue-acls.xml ./13-mapreduce-JOBTRACKER/fair-scheduler.xml ./13-mapreduce-JOBTRACKER/mapred-site.xml ./13-mapreduce-JOBTRACKER/core-site.xml ./13-mapreduce-JOBTRACKER/capacity-scheduler.xml ./13-mapreduce-JOBTRACKER/hdfs-site.xml # <name>dfs.replication</name> # <value>3</value> ./9-hdfs-NAMENODE/core-site.xml ./9-hdfs-NAMENODE/hdfs-site.xml # <name>dfs.replication</name> # <value>3</value> ./19-deploy-client-config/hadoop-conf/core-site.xml ./19-deploy-client-config/hadoop-conf/hdfs-site.xml # <name>dfs.replication</name> # <value>3</value> ./10-hdfs-DATANODE/core-site.xml ./10-hdfs-DATANODE/hdfs-site.xml # <name>dfs.replication</name> # <value>3</value> ./7-hdfs-NAMENODE-format/core-site.xml ./7-hdfs-NAMENODE-format/hdfs-site.xml # <name>dfs.replication</name> # <value>3</value> ./20-deploy-client-config/hadoop-conf/mapred-site.xml ./20-deploy-client-config/hadoop-conf/core-site.xml ./20-deploy-client-config/hadoop-conf/hdfs-site.xml # <name>dfs.replication</name> # <value>3</value> ./11-hdfs-NAMENODE-createtmp/core-site.xml ./11-hdfs-NAMENODE-createtmp/hdfs-site.xml # <name>dfs.replication</name> # <value>3</value> ./8-hdfs-SECONDARYNAMENODE/core-site.xml ./8-hdfs-SECONDARYNAMENODE/hdfs-site.xml # <name>dfs.replication</name> # <value>3</value>
