5. Loop through files and directories in a for loop To loop through files and directories under a specific directory, just cd to that directory, and give * in the for loop as shown below. The following example will loop through all the files and directories under your home directory. $ c...
This type of for loop is characterized by counting. The range is specified by a beginning (#1) and ending number (#5). The for loop executes a sequence of commands for each member in a list of items. A representative example in BASH is as follows to display welcome message 5 times wit...
the for loop will be executed a total of 5 times, once for each item in the list. The current item from the list will be stored in a variable “varname” each time through the loop. This “varname” can
Bash For Loop 示例 1. 解压所有 Zip 文件 以下示例在根目录中查找与“*.zip*”匹配的文件列表,并在该 zip 文件所在的相同位置创建一个新目录,并解压缩该 zip 文件内容。 # cat zip_unzip.sh #! /bin/bash # Find files which has .zip for file in `find /root -name "*.zip*" -type f` do ...
bash shell中循环语句的写法有:for-in、for-i、while、until; 循环中断控制符有:break、continue 循环语句示例 for-in #! /bin/bash for num in 1 22 14 55 do echo $num done echo "1 2 3 4 5 loop output" for num in `seq 5` do
“ for循环”是bash编程语言的语句,它允许重复执行代码。 for循环被归类为迭代语句,即bash脚本中进程的重复。 例如,您可以运行UNIX命令或任务5次,或使用for循环读取和处理文件列表。 可以在shell提示符下或在shell脚本本身内使用for循环。 更详细信息 请看:Bash For Loop Examples In Linux ...
Combining aforloop withxargsmakes sense when we need to preprocess or filter data before running some tasks in parallel. For example, aforloop can iterate over each file, check a condition such as file size, and then usexargsto parallelize a job on only the eligible files: ...
#!/bin/bash # 创建一个包含多个文件名的数组 files=("file1.txt" "file2.txt" "file3.txt") # 使用for循环遍历数组中的每个文件名 for file in "${files[@]}" do # 打印文件名 echo "处理文件:$file" # 在这里可以执行其他命令,对文件进行处理 done 在上面的示例中,我们创建了一个包含多个文件...
for i in 1 2 3 do echo $i done # this can be anything. # In for-loop-files.sh you can see more of this with files # auto generated list echo "=== ranges ==" for i in {1..5} do echo $i done # like this, you can quickly generate a range of numbers # This also works...
