Top Forums UNIX for Beginners Questions & Answers How to have local shell variables in a ksh script seen on remove server in SSH block? Post 303036281 by MadeInGermany on Friday 21st of June 2019 10:58:34 AM

I think that code in unquoted here documents is problematic: too many levels of quoting.
In zsh you can chain two (or more) redirections
Code:
#!/bin/zsh
filepath=/xxx/yyy/zzz/
filename=xyz

ssh uid@hostname << EOT1 << 'ENDSSH'
filepath=$filepath
filename=$filename
EOT1
.
.
if [[ -e ${filepath}${filename} ]]; then
....
....
fi

ENDSSH

The first part EOT1 is unquoted and assigns the local variables to the remote variables.
Instead of directly feeding the login shell (where ssh might complain that a tty is missing) it is more correct to run an explicit /bin/sh (or /bin/bash)
Code:
ssh uid@hostname /bin/sh -s << EOT1 << 'ENDSSH'

Having this, with any standard shell you can pass the local variables as parameters
Code:
filepath=/xxx/yyy/zzz/
filename=xyz

ssh uid@hostname /bin/sh -s $filepath $filename << 'ENDSSH'
filepath=$1
filename=$2
.
.
if [[ -e ${filepath}${filename} ]]; then
....
....
fi

ENDSSH

fizsh

fizsh(1)							       fizsh								  fizsh(1)

NAME

       fizsh - friendly interactive zshell.

SYNOPSIS

       fizsh [OPTIONS]... [ARGUMENTS]...

DESCRIPTION

       Fizsh is a front end to zsh. Fizsh provides zsh with interactive syntax-highlighting and a MATLAB-like history-search. Fizsh is intended to
       look and feel similar to fish. A distinguishing feature is that fizsh can handle Bourne compatible syntax. This is because fizsh is a front
       end to zsh.  Fish uses its own syntax.

CONFIGURATION

       $HOME/.fizsh is the directory where fizsh keeps its configuration files. The file $HOME/.fizsh/.fizshrc serves as the user's local startup
       script. Local customizations, such as aliases and functions, can be added here. $HOME/.fizsh/.fizshrc allows the same syntax as
       $HOME/.zshrc under zsh. $HOME/.fizsh/.fizsh_history is default name of fizsh's history file.

       The other files in $HOME/.fizsh are installed by /usr/bin/fizsh. In order to reinstall these files use: /usr/bin/fizsh -r or /usr/bin/fizsh
       --reinstall.

       Compared to the default configuration of zsh, fizsh additionally sets the options "histignorealldups", "histignorespace",
       "histreduceblanks", "incappendhistory", "interactivecomments", "promptsubst", "correct" and "nobeep".

       For further configuration details consult zsh's man pages.

INVOCATION

       Fizsh is meant to be invoked without options and without command-line arguments.

       The only supported command-line options are "--version", "--help", "--login", "--reinstall", "-v", "-h", "-l" and "-r". "--version" or "-v"
       yields fizsh's version number. "--help" or "-h" causes fizsh to print brief usage information. "--login" or "-l" cause fizsh to be a login
       shell.  "--reinstall" or "-r" will reinstall some of fizsh's configuration files (see above).

       If invoked with other command-line options and/or arguments fizsh will silently revert to zsh.

BUGS

       There are no known bugs at the moment. Bug reports, bug fixes and other comments are welcome.
