shell將多行文字重定向到檔案
阿新 • • 發佈：2019-01-09
在shell中，使用Here Document方式將文字重定向到檔案，格式如下：
(
cat << EOF
要寫的文字
EOF
) > 目標檔案示例test.sh：
#! /bin/sh ( cat << EOF { "warehouse":"$1", "ipaddr": "$2", "bindaddr": "$2:9995", "repopath": "./repo/", "kafka": "100.69.168.38:9095", "topic": "AgentHeartBeat", "partition": "1" } EOF ) > agent/conf/agent.conf.json1
執行"test.sh ys 192.168.1.80"的結果：
[[email protected] monitor-agent]# cat agent/conf/agent.conf.json1
{
"warehouse":"ys",
"ipaddr": "192.168.1.80",
"bindaddr": "192.168.1.80:9995",
"repopath": "./repo/",
"kafka": "192.168.1.2:9095",
"topic": "AgentHeartBeat",
"partition": "1"
}
