bash - Running multiple commands through ssh -

i trying run multiple commands using ssh not getting syntax right. please give me help?

ssh "$user"@"$ip" " \     current_hostname=$(hostname); \     sed -c -i 's/\($target_key *= *\).*/\1$replacement_value/' $distro_file; \     sed -c -i 's/$current_hostname/$replacement_value/' $config_file; \     hostname $replacement_value" 

those commands work fine if run locally, getting following error when trying run them through ssh:

sed: -e expression #1, char 0: no previous regular expression 

it seems error comes from

sed -c -i 's/$current_hostname/$replacement_value/' $config_file; \ 

as trying read $current_hostname set before in ssh itself. not sure how read variable back. clue please?

edited code:

ssh "$user"@"$ip" "current_hostname=\$(hostname);     sed -c -i \"s/\($target_key *= *\).*/\1$replacement_value/\" $distro_file;     sed -c -i \"s/\$current_hostname/$replacement_value/\" $config_file;     hostname $replacement_value" 

this works! lot!

thanks.

all variables double quotes evaluated bash before sending parameter remote machine.

if want preserve $variable need use single quotes instead (escaping single quotes within commands), or escape dollar signs want evaluated on server side.

you don't need escape line break , use semicolon. line breaks included in parameter.
