Question

我尝试编写脚本代码。它问我有多少＆＃34;什么＆＃34;你要？我回答了一个像10的数字

#!/bin/bash
echo -n "Please enter some input: "
read input

现在我喜欢执行10次命令，包括从001到010的数字例如，我得到了正确的数字：

seq -f "%03g" 1 $input

但是如何使用这个数字执行now命令，如：

command anyname-001 -some -parameter
command anyname-002 -some -parameter
command anyname-003 -some -parameter

...

thanx求助

Answer 1

使用GNU bash：

for ((i=1;i<=$input;i++)); do
  printf -v number "%03d" "$i"
  echo command anyname-${number} -some -parameter
done

如果一切正常，请删除echo。

只需在范围内使用for循环。这应该可以解决问题。

一行（好吧，正式两行）：

#!/bin/bash
printf 'command anyname-%03d -some -parameter\n' $(seq $1)

将脚本调用为：

$ script 10
command anyname-001 -some -parameter
command anyname-002 -some -parameter
command anyname-003 -some -parameter
command anyname-004 -some -parameter
command anyname-005 -some -parameter
command anyname-006 -some -parameter
command anyname-007 -some -parameter
command anyname-008 -some -parameter
command anyname-009 -some -parameter
command anyname-010 -some -parameter

bash脚本。运行带有计数数字和名称的命令
