安装新版gawk

下载

[root@docker-01 ~]# wget --no-check-certificate https://mirrors.tuna.tsinghua.edu.cn/gnu/gawk/gawk-4.2.0.tar.gz

解压进入解压目录

[root@docker-01 ~]# tar xf gawk-4.2.0.tar.gz 
[root@docker-01 ~]# cd gawk-4.2.0

编译

[root@docker-01 gawk-4.2.0]# ./configure --prefix=/usr/local/gawk4.2 && make && make install

创建软件连接，让awk指向刚新装的gawk版本

[root@docker-01 gawk-4.2.0]# ln -fs /usr/local/gawk4.2/bin/awk /usr/bin/awk 

此时调用awk将调用新的gawk，调用gawk将调用旧的awk

[root@docker-01 gawk-4.2.0]# awk --version
