SSH in unix


To access another server/machine we use ssh to authenticate and do communication.

Syntax :
>ssh user@server -P password

This will login to another machine from our local system.

Sometime we may need to fetch the content from another file in remote system , in this case we can use the below form

>ssh user@server -P password "cat /home/abc/1.txt | grep <Text to search>"

If we echo the above we can see the content from our system

Eg :

echo $(ssh user@server -P password "cat /home/abc/1.txt | grep MMDDYYYY")

This will fetch the line with the date format specified from the file.
