comm shell command

常用Shell命令

BASEDIR=$(cd $(dirname $) && pwd)
cd $BASEDIR>/dev/null

选取两个文件中相同的部分：(Must sort first)

comm - <(sort /tmp/gcs.calix.com-wifi-pm-per-radio_50|uniq) <(sort /tmp/gcs.calix.com-wifi-pm-per-radio_dupcheck_50|uniq)

CURL:

curl -H "Accept: application/json" -H "Content-type: application/json" -X POST -d '{"id":100}' http://localhost/test/adduser

变量处理：

#根据变量值获取变量
pass=`eval echo '$'psql_"${env}_pass"`

数值处理：

#判断是否为数字
if [ -n "$org" ] && [ "$org" -eq "$org" ] >/dev/null; then
    echo "$org need process"
    cat result.txt|grep $org>_result_${org}

EOF
chmod 751 100-custom

EOF

EOF是END Of File的缩写,表示自定义终止符.既然自定义,那么EOF就不是固定的,可以随意设置别名,在linux按ctrl-d就代表EOF.

EOF一般会配合cat能够多行文本输出.

通过cat配合重定向能够生成文件并追加操作,在它之前先熟悉几个特殊符号:
< :输入重定向
> :输出重定向
>> :输出重定向,进行追加,不会覆盖之前内容
<< :标准输入来自命令行的一对分隔号的中间内容.

其用法如下:
<<EOF //开始
....
EOF //结束

还可以自定义，比如自定义：
<<BBB //开始
....
BBB //结束

）向文件test.sh里输入内容。
[root@slave-server opt]# cat << EOF >test.sh
>
>
> asdfasdfs
> EOF

[root@slave-server opt]# cat test.sh 

asdfasdfs

追加内容
[root@slave-server opt]# cat << EOF >>test.sh
>
>
> EOF
[root@slave-server opt]# cat test.sh 

asdfasdfs

覆盖
[root@slave-server opt]# cat << EOF >test.sh
>
> EOF
[root@slave-server opt]# cat test.sh

全量清除Rancher/K8S 节点

docker stop $(docker ps -aq)
docker system prune -f

获取Rancher dockerid

docker ps | grep -E "rancher/rancher:|rancher/rancher " | awk '{ print $1 }'

启动Rancher

sudo docker run -d --name rancher --restart=unless-stopped -p : -p : rancher/rancher:latest

获取dockerId

docker ps -aq

1.awk command

1.1 Purpose 1: want to distinct and then count and sort by num

1.1.1 Command: cat result.txt|awk '{print $1}'|uniq -c|sort -k 1n

Sort parameters:

　-k: sort by key (in this case column, pairs with -t)

　　-n: sort as a number

　　-r: reverse order

　　(optional) -t: in case you want to change the key separator (default: space)

Uniq parameter:

　　-w: choose the first N characters

Explanation:

　　In your problem, we need to first sort the first column and then the second one. So there is a -k 1,1 followed by -k 2,2. But, the second key (ONLY) must be sorted as a number and in the reverse order. Thus, it should be -k 2nr,2.

Note that if the -n or -r sort parameters are outside -k parameter, they are applied to the whole input instead of specific keys.

Lastly, me must find the unique lines, but matching only the first 4 chars. Thus, uniq -w 4

2. Ubuntu 安装ping curl
