我正在编写一个 shell 脚本，遇到了这个我无法解决的问题
以下命令应该查找/.
PATHS_SHELL=$(sudo find / -name '*.sh')
如果我执行该命令而不将其分配给变量，它就可以正常工作。但是当我将它分配给PATHS_SHELL.它给了我一个带有以下文本的无限循环

在这个无休止的输出之前，输出的是许多 shell 文件路径，这是预期的正确输出。例如
/usr/src/linux-headers-5.15.0-48/tools/testing/selftests/netfilter/ipvs.sh
/usr/src/linux-headers-5.15.0-48/tools/testing/selftests/netfilter/ipip-conntrack-mtu.sh
/usr/src/linux-headers-5.15.0-48/tools/testing/selftests/netfilter/conntrack_tcp_unreplied.sh
/usr/src/linux-headers-5.15.0-48/tools/testing/selftests/netfilter/nft_fib.sh
/usr/src/linux-headers-5.15.0-48/tools/testing/selftests/netfilter/nft_nat_zones.sh
/usr/src/linux-headers-5.15.0-48/tools/testing/selftests/netfilter/nft_meta.sh
/usr/src/linux-headers-5.15.0-48/tools/testing/selftests/netfilter/nft_zones_many.sh

看来您使用了保留变量$PATH来索引字符串$PATHS_SHELL。该变量保存要搜索命令的目录列表，因此当您覆盖它时，将无法再找到任何脚本命令。因此会出现有关未找到命令的错误。
