英文:
Skip wrong password for 7z extraction Ubuntu
问题
Sure, here's the translated content:
任务是从存储在“IN”目录中的多个受密码保护的存档中提取文件，使用7zip包，密码存储在名为“PASS”的列表中。我遇到了一个问题：当密码错误时，7zip会创建空文件夹和文件。是否有方法可以跳过错误的密码并继续下一次迭代？
这是我的bash脚本：
FILES=./IN/*
PASS=('1' '2' '3')
for f in $FILES
do
for psd in "${PASS[@]}"
do
if 7z x -y -p"$psd" -o./OUT $f | grep 'ERROR'; then
break
fi
done
done
请注意，我已经修复了脚本中的引号问题，并将${PASS[@]}括在双引号中以正确地处理密码列表。
英文:
The task is to extract files from multiple password-protected archives stored in “IN” directory with 7zip package, passwords stored in list “PASS”. I have a problem: when the password is wrong 7zip creates empty folders and files. Are there any ways to skip wrong password and go to next iteration?
Here’s my bash script
FILES=./IN/*
PASS=(‘1’ ‘2’ ‘3’)
for f in $FILES
do
for psd in $(PASS[@])
do
if 7z x -y -p”$psd” -o./OUT $f | grep ‘ERROR’; then
break
fi
done
done

以下是已翻译的内容：
这里有一个建议：在尝试提取之前，使用 7zz t（测试归档完整性）来确定您列表中的给定密码是否有效。
示例：
#! /bin/sh
WORKDIR='path/to/your/work/dir'
PW='1 2 3'
for File in "$WORKDIR"/*.zip
do
test -r "$File" || continue
for Password in $PW
do
7zz t -p"$Password" "$File" >/dev/null 2>&1 \
&& { 7zz x -p"$Password" "$File"; break; }
done || echo "warning: could not extract file \"$File\" (no valid password found)"
done
备注：
- 如果您已安装了“7zip”软件包，则归档命令名称为
7zz。 - 如果您已安装了“p7zip-full”软件包（7-Zip的Unix CLI端口），则归档命令名称为
7z。
在Linux Debian 11上进行了测试。
希望这有所帮助。
英文:
Here's a suggestion : use 7zz t (test archive integrity) to determine if a given password in your list is valid before attempting extraction.
Example:
#! /bin/sh
WORKDIR='path/to/your/work/dir'
PW='1 2 3'
for File in "$WORKDIR"/*.zip
do test -r "$File" || continue
for Password in $PW
do 7zz t -p"$Password" "$File" >/dev/null 2>&1 \
&& { 7zz x -p"$Password" "$File"; break; }
done || echo "warning: could not extract file \"$File\" (no valid password found)"
done
Note:
-
if you've installed package "7zip", the archiver command name is
7zz. -
if you've installed package "p7zip-full" (the Unix CLI port of 7-Zip), the archiver command name is
7z.
Tested on Linux Debian 11.
Hope that helps.
