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 is easiest to use loops directly
Bash For Loop In One Line with Files # for i in *; do echo "Found the following file: $i"; done # for i in `cat filelist.txt`; do echo ${i}; done; if a line may include spaces better use a while loop: # cat filelist.txt | while read LINE; do echo "${LINE}"; done ...

Examples of Bash for Loops There are two ways to use the For Loop in bash, one is in the ‘c-style syntax,’ and the other is ‘for-in.’ The syntax for the c-style for loops is as follows: for ((INITIALIZATION; TEST; STEP)) do [COMMANDS] done Meanwhile, as aforementioned, the...
在Bash For Loop中使用“Continue”语句 “ continue ”语句是控制脚本运行方式的内置命令。除了bash脚本之外,它还用于Python和Java等编程语言。continue语句在满足特定条件时停止循环内的当前迭代,然后恢复迭代。可以看看如下所示的for循环。 #!/bin/bash

Hopefully, these examples have demonstrated the power of aforloop at the Bash command line. You really can save a lot of time and perform tasks in a less error-prone way with loops. Just be careful. Your loops will do what you ask them to, even if you ask them to do something destr...
