In the Bash script, we have many ways to do parsing. We can use cut, as we saw in the previous example, or use awk, or we can use a simple loop to read the file line by line. In the same location as the CSV file, create a Bash file (e.g., parse.sh) and fill it with ...

a.awk awk是处理文本文件最有用的命令。它一行一行地在整个文件上运行。默认情况下,它使用空格分隔字段。awk命令最常用的语法是 awk '/search_pattern/ { action_to_take_if_pattern_matches; }' file_to_parse 1. 让我们采取以下文件/etc/passwd。以下是此文件包含的示例数据: ...
1、如是start,那么创建/var/lock/subsys/script.sh,显示启动成功; 2、如果参数是stop,则删除/var/lock/subsys/script.sh,显示停止成功 3、如果restart,则删除,再创建,显示成功; 4、如果status, 如果文件存在,则显示running,否则,显示stopped #!/bin/bash ...
