> “email”: “johndoe@example.com”,> “message”: “Hello, world! This is a very long message that needs to be split into multiple lines.”> }’ \> https://example.com/api/endpoint“` 在这个例子中,换行命令允许我们将长的JSON字符串分成多行,以提高可读性。 3. 将长命令保存到脚本文件...

When no array variable name is provided to the mapfile command, the input will be stored into the $MAPFILE variable. Note that the mapfile command will split by default on newlines character but will preserve it in the array values, you can remove the trailing delimiter using the -t ...
Bash's exit status is the exit status of the last command executed in the script. If no commands are executed, the exit status is 0. An attempt is first made to open the file in the current directory, and, if no file is found, then the shell searches the directories in PATH for ...
In this example, themapfilecommand reads lines from a file into an array. We then use a ‘for’ loop to process each line. Exploring Related Concepts: Associative Arrays in Bash Once you’re comfortable with regular arrays and loops in Bash, you might want to explore related concepts like...
