Bash是一种Unix Shell和命令语言,它是一种脚本语言,用于在Unix和Linux系统中执行命令和自动化任务。通过for-in-loop执行文件是指使用Bash中的循环结构来遍历文件列表并执行相应的操作。 在Bash中,可以使用for-in-loop来遍历文件列表。具体的语法如下: 代码语言:txt 复制 for file in <文件列表> do # 执行操作,...
In other words, Loops are easy and best to perform repetitive tasks. Its use is even more significant when working with scripting languages such as Bash. Our article will provide all the basics of the for loops in Bash. There are various loops constructs such as the while loop, the until...
“ for循环”是bash编程语言的语句,它允许重复执行代码。 for循环被归类为迭代语句,即bash脚本中进程的重复。 例如,您可以运行UNIX命令或任务5次,或使用for循环读取和处理文件列表。 可以在shell提示符下或在shell脚本本身内使用for循环。 更详细信息 请看: Bash For Loop Examples In Linux for循环语法 数字范围的...
1. Using for ... in statement 2. Using for ((exp1, exp2, exp3)) statement The result will be: Why you can use a bash for loop in one line If you use bash on the command line, this will not guarantee that for loops are inserted into the script. In order to prevent this, it...
“for” loop in a sequence is said to be “nested”. Therefore, we have decided to use the “nested” for loops in Bash programming within our examples of today’s article. So, let’s start with the opening of the terminal shell in the Ubuntu 20.04 system via the “Ctrl+Alt+T” ...
$bashbash.sh Example 02: The second easy method to use the “for” loop is to mention its iterations within the curly brackets. Open the same bash file once again with the “nano” command. Add the bash extension in it first. After that, the “for” loop has been initialized with the...
for n in {1..7}; do echo $n done Once the shell script is executed, all the values in the range are listed, similar to what we had insimple loops. Bash For Loop with Ranges Example Additionally, we can include a value at the end of the range that is going to cause thefor loop...
