如何将命令行参数“序列化”和“反序列化”到字符串或从字符串中提取参数?

创建了两个脚本:一个将其参数序列化为 [a-ZA-Z0-9=_]* http://vi-server.org/vi/bin/serialize.sh ,其他启动此命令行(带有可选的前置参数) http://vi-server.org/vi/bin/deserialize.sh .

#!/bin/bash
n=$#;
for ((i=0; i<$n; ++i)); do
    if [ -z "$1" ]; then
        echo 1
    else
        printf '%s' "$1" | base64 -w 0
        echo
    fi
    shift
done | tr '\n' '_'
echo -n "0"

反序列化:

#!/bin/bash
if [ -z "$1" ]; then
    echo "Usage: deserialize data [optional arguments]"
    echo "Example: \"deserialize cXFx_d3d3_0 eee rrr\""
    echo "    will execute \"eee rrr qqq www\""
    exit 1;
fi

DATA="$1"; shift

i=0

for A in ${DATA//_/' '}; do
    if [ "$A" == "0" ]; then 
    break;
    fi              
    if [ "$A" == "1" ]; then 
    A=""
    fi              
    ARR[i++]=`base64 -d <<< "$A"`
done
exec "$@" "${ARR[@]}"

例子:

deserialize `serialize qqq www` echo

与另一个答案中的Bash脚本不兼容

将命令行参数序列化到的脚本 [a-zA-Z0-9=_]* 字符串: http://vi-server.org/vi/bin/serialize

#!/usr/bin/perl
use MIME::Base64;
map {print encode_base64($_,'')."_" } @ARGV;

反序列化它的脚本(可选地在其他参数前面加上前缀): http://vi-server.org/vi/bin/deserialize

#!/usr/bin/perl
use MIME::Base64;
if($#ARGV<0) {
    print << "EOF";
Usage: deserialize data [optional prepended arguments]
Example: deserialize \$(serialize 3 4 " 5 " "" "'6'" '`8`') echo 1 2
EOF
    exit
}
my @A = map {decode_base64($_)} split '_', shift @ARGV;
exec (@ARGV,@A);
