passing array to script via ssh

[trickstar]

Hello all,

I m having difficulties now to get my array back on script on remote server.

I' m passing the array like this:

ssh $USER@$SERVER command "'$(echo ${array[@]})'"

I get it back on my server in the forms of string but i cant convert it back to array.
On the remote server i m using korn shell.
On my machine bash.

Thank you for helping.

So "command" is a ksh script? In that case, the arguments are already positional parameters. Isn't that enough?

And how would loop through it ?
I tried different ways but it always print just all my array element as just one string.
In my loop there is just one loop that prints a single string with all my array element.

$ var="1 2 3 4"
$ array=($var)
$ echo ${array[1]}
2

On the client side my in my script i have,

num="1 2 3 4"
ssh $USER@$SERVER remote_script "'$(echo ${num[@]})'"

On the server side i have:

num="$1"
for i in "${num[0]}"
  echo "num $i"
done

and it prints "num 1 2 3 4" instead of :
num 1
num 2
num 3
num 4

$ var="1 2 3 4"
$ array=($var)
$ echo ${array[1]}
2

I tried it already like this on server script :

num=($1)
for i in "${num[@]}"
do
  echo "num $i"
done

but as i said in my first post, im using korn shell on the server, and it seems that this syntax is not working with this shell as it says

syntax error: '(' unexpected

Works for my korn shell.

Hi.

Newer versions have bash-like array setting syntax:

#!/usr/bin/env ksh

# @(#) s1       Demonstrate ksh array setting syntax.

echo
export LC_ALL=C
echo "Environment: LC_ALL = $LC_ALL"
echo "(Versions displayed with local utility \"version\")"
version >/dev/null 2>&1 && version "=o" $(_eat $0 $1)

echo
echo " With earlier syntax:"
set -A b goodbye moon
print ${b[*]}

echo
echo " With 93s+ syntax:"
a=( hello world )
print ${a[*]}

exit 0

Producing:

$ ./s1

Environment: LC_ALL = C
(Versions displayed with local utility "version")
SunOS 5.10
ksh M-11/16/88i

 With earlier syntax:
goodbye moon

 With 93s+ syntax:
./s1[18]: syntax error at line 18 : `(' unexpected

The first seems to be allowed in earlier ksh versions and even in pdksh ... cheers, drl
