工作正常，除非您有空格或转义字符。我没有找到在这种情况下捕获参数并发送到脚本中的ssh的方法。

这可能是有用的，但如此丑陋

_command_opts=$( echo "$@" | awk -F\- 'BEGIN { OFS=" -" } { for (i=2;i<=NF;i++) { gsub(/^[a-z] /,"&@",$i) ; gsub(/ $/,"",$i );gsub (/$/,"@",$i) }; print $0 }' | tr '@' \' )

bash和其他类似bourne的炮弹:

bar "$@"

使用“$@”(适用于所有POSIX兼容程序)。

[…)， bash提供了“$@”变量，它扩展为所有用空格分隔的命令行参数。

以Bash为例。

如果在带引号的字符串中包含$@和其他字符，当有多个参数时，行为是非常奇怪的，只有第一个参数包含在引号中。

例子:

#!/bin/bash
set -x
bash -c "true foo $@"

收益率:

$ bash test.sh bar baz
+ bash -c 'true foo bar' baz

但是先赋值给另一个变量:

#!/bin/bash
set -x
args="$@"
bash -c "true foo $args"

收益率:

$ bash test.sh bar baz
+ args='bar baz'
+ bash -c 'true foo bar baz'

如果你确实希望传递相同的参数，请使用“$@”而不是普通的$@。

观察:

$ cat no_quotes.sh
#!/bin/bash
echo_args.sh $@

$ cat quotes.sh
#!/bin/bash
echo_args.sh "$@"

$ cat echo_args.sh
#!/bin/bash
echo Received: $1
echo Received: $2
echo Received: $3
echo Received: $4

$ ./no_quotes.sh first second
Received: first
Received: second
Received:
Received:

$ ./no_quotes.sh "one quoted arg"
Received: one
Received: quoted
Received: arg
Received:

$ ./quotes.sh first second
Received: first
Received: second
Received:
Received:

$ ./quotes.sh "one quoted arg"
Received: one quoted arg
Received:

Bar "$@"将等价于Bar "$1" "$2" "$3" "$4"

注意，引号很重要!

"$@"， $@， "$*"或$*将在此stackoverflow回答中描述的转义和连接方面各自表现略有不同。

一个密切相关的用例是在一个参数中传递所有给定的参数，就像这样:

Bash -c“bar \”$1\“$2\”$3\“$4\””。

我使用@kvantour的答案的一个变体来实现这一点:

Bash -c "bar $(printf - ' ' %s ' ' ' $@")"
