linux - 如何在不解压缩和重新压缩的情况下重命名 zip 存档中的文件？

Question

我需要将 zip 文件中的所有文件从 AAAAA-filename.txt 重命名为 BBBBB-filename.txt，我想知道我是否可以自动化此任务无需提取所有文件、重命名然后再次压缩。一次解压一个，重命名并再次压缩是可以接受的。

我现在拥有的是:

for file in *.zip
do
    unzip $file
    rename_txt_files.sh
    zip *.txt $file
done;

但我不知道是否有更好的版本，我不必使用所有额外的磁盘空间。

计划

• find offsets of filenames with strings
• use dd to overwrite new names ( note will only work with same filename lengths ). otherwise would also have to find and overwrite the filenamelength field..

尝试此操作之前备份您的 zip 文件

zip_rename.sh

#!/bin/bash

strings -t d test.zip | \
grep '^\s\+[[:digit:]]\+\sAAAAA-\w\+\.txt' | \
sed 's/^\s\+\([[:digit:]]\+\)\s\(AAAAA\)\(-\w\+\.txt\).*$/\1 \2\3 BBBBB\3/g' | \
while read -a line; do
  line_nbr=${line[0]};
  fname=${line[1]};
  new_name=${line[2]};
  len=${#fname};
#  printf "line: "$line_nbr"\nfile: "$fname"\nnew_name: "$new_name"\nlen: "$len"\n";
  dd if=<(printf $new_name"\n") of=test.zip bs=1 seek=$line_nbr count=$len conv=notrunc  
done;

输出

$ ls
AAAAA-apple.txt  AAAAA-orange.txt  zip_rename.sh
$ zip test.zip AAAAA-apple.txt AAAAA-orange.txt 
  adding: AAAAA-apple.txt (stored 0%)
  adding: AAAAA-orange.txt (stored 0%)
$ ls
AAAAA-apple.txt  AAAAA-orange.txt  test.zip  zip_rename.sh
$ ./zip_rename.sh
