execute part of shell script on remote machine

Question

I am logging into remote machine through shell script (by placing ssh command in script). After ssh command ,The remaining lines of the script are getting executed on the curre

Answer 1

One possible solution would be to use a heredoc as in the following example:

$ ssh example.foo.com -- <<@@
> ls /etc/
> cat /etc/passwd
> @@

Basically everything between the @@ on the first line and the last line will be executed on the remote machine.

You could also use the contents of a file by either reading the contents of the file into a variable:

$ MYVAR=`cat ~/foo.txt`
$ ssh example.foo.com -- <<@@
> $MYVAR
> @@

or by simply performing the same action inside the heredoc:

$ ssh example.foo.com -- <<@@
> `cat ~/foo.txt`
> @@
