查找“找不到命令".在bash循环中执行时

问题描述

我正在尝试编写bash脚本以生成文件列表.我以为我会在一个循环中简单地调用查找".不幸的是，在循环中时，它生成了找不到:命令未找到"错误，我也不知道为什么.

I'm trying to write a bash script to generate lists of files. I figured I'd simply call 'find' within a loop. Unfortunately it generated a "find: command not found" error when in the loop and I don't know why.

为了简短起见，此精简版复制了该问题，而不会在不相关的代码中陷入困境.

To keep things short, this cut-down version replicates the issue without bogging us down in irrelevant code.

#!/bin/bash
IFSprev=$IFS
IFS=$'|'
PATHS='openvpn|vms'
SOURCE='/mnt/store/'

#find "${SOURCE}vms" -type f
for PATH in ${PATHS}
do
   echo -----------------------------------
   find "${SOURCE}${PATH}" -type f
done
IFS=$IFSprev

在进行故障排除时，我添加了第一个"find"命令……并添加了该命令，随后它在循环中起作用.如果我再次注释掉，循环中的查找"将恢复为抛出错误.

While troubleshooting, I added the first 'find' command... with that added, it subsequently works within the loop. If I comment it out again, the 'find' in the loop reverts to throwing the error.

鉴于我要将循环输出重定向到文件，我可以使用额外的"find"命令，甚至可以重定向到null.但是，我是一个好奇的家伙，我真的很想找出问题所在.

Given I'm gonna be redirecting the loop output to a file, I can live with the extra 'find' command or even just redirect to null. However, I'm an inquisitive kinda guy and I really want to find what the problem is.

感谢您的任何输入.

推荐答案

它正在$PATH中寻找find ...您的脚本已被破坏.

It's looking for find in $PATH... which your script has destroyed.
