Question

我没有幸运的bash脚本知识。我需要一个脚本，将cd从CD拷贝到目的地并将其重命名。这是我的代码

#!/bin/bash

mount /dev/cd0 /mnt/

for file in /mnt/*
do
if($file == SO_CV*)
    cp SO_CV* /usr/castle/np_new/CVFULLPC.BIN
else if($file == SO_PC*)
    cp SO_PC* /usr/castle/np_new/PCMAP.BIN
else if($file == MS_PC*)
    cp MS_PC* /usr/castle/np_new/FULLPC.BIN
else if($file == MS_MC*)
        cp MS_MC* /usr/castle/np_new/MBFULLPC.BIN
done

umount /mnt/

有人可以告诉我这是否是有效的bash脚本，或者我可能犯了什么错误。

语法问题。试试这段代码：

#!/bin/bash

mount /dev/cd0 /mnt/

for file in /mnt/*; do
   if [[ "$file" == SO_CV* ]]; then
      cp SO_CV* /usr/castle/np_new/CVFULLPC.BIN
   elif [[ "$file" == SO_PC* ]]; then
      cp SO_PC* /usr/castle/np_new/PCMAP.BIN
   elif [[ "$file" == MS_PC* ]]; then
      cp MS_PC* /usr/castle/np_new/FULLPC.BIN
   elif [[ "$file" == MS_MC* ]]; then
      cp MS_MC* /usr/castle/np_new/MBFULLPC.BIN
   fi
done

umount /mnt/

替代方案：

#!/bin/bash

error_in_cp () {
   { printf "An ERROR occured while trying to copy: '\s' to its dest file.\n" "$@"
     printf "Maybe there were more than 1 file ? or you didn't have the rights necessary to write the destination?"
     printf "Exiting..."
   } >&2  #to have it on STDERR
   exit 1
}    

mount /dev/cd0 /mnt/ &&
for file in /mnt/*; do
   case "$file" in
     SO_CV*) cp -p SO_CV* /usr/castle/np_new/CVFULLPC.BIN || error_in_cp "$file" ;;
     SO_PC*) cp -p SO_PC* /usr/castle/np_new/PCMAP.BIN    || error_in_cp "$file" ;;
     MS_PC*) cp -p MS_PC* /usr/castle/np_new/FULLPC.BIN   || error_in_cp "$file" ;;
     MS_MC*) cp -p MS_MC* /usr/castle/np_new/MBFULLPC.BIN || error_in_cp "$file" ;;
     *)      echo "oops, forgot to handle that case: '$file' . ABORTING. "
             exit 1
             ;;
   esac
done   # no "&&" here so you always umount /mnt/ even if you aborted the copy or the latest command went wrong
umount /mnt/

注意：我将“cp”更改为“cp -p”以更改权利＆amp;时间...如果需要调整。

请注意“＆amp;＆amp;”在行的末尾是好的（不需要：

 command && \
     something

）

如果有超过1个元素，则可能需要在每个部分周围添加{和}（此处，“case ... esac”是一个元素，所以没关系）
