Shell Programming and Scripting

A construct I often use:

Code:

ssh username@host exec sh -s -- "arg1" "arg2" "arg3" <<"EOF"

# Literal, unescaped script contents to be executed on the remote side.

echo "arg1 is $1"
echo "arg2 is $2"
echo "arg3 is $3"

# The EOF must be at the beginning of the line and not indented.
EOF

test.sh contains the commands.

Code:

ssh -qtt user@$host "sh -s '${version}'" < test.sh

works absolutely fine. I run into issues only while looping.

??? That makes no sense. Why would you feed ssh username@host into ssh username@host ? That instructs the remote host to try and ssh into itself, but will fail because $host and $version are unset and test.sh does not exist. I am extremely suspicious of this ever working, especially since only now have you fixed the syntax errors that I noticed...

This test.sh needs to be a separate file, not the same one, so it can contain this:

Code:

cd /build && cp -p web.zip web.zip_${1} && rm -rf test && unzip /build/web.zip && cd /bin

Note the $1 instead of $version, for reasons I gave earlier.

Then you should do

Code:

ssh username@host exec /bin/sh -s -- ${version} < test.sh

and have the remote host run the sequence of commands stored in test.sh.

Try it without the -qtt. That may misbehave when you don't have a terminal or want it to be interactive.
