The SSH client program can be used for logging into a remote machine or server and for executing commands on a remote machine. When command is specified, it is executed on the remote host/server instead of a login shell. The syntax is as follows for executing commands over ssh:
ssh user1@server1 command1
ssh user1@server1 'command2'
ssh user1@server1 'command1 | command2'
The ssh client will login to a server called server1, using user name called user1 and run a command call command1.
Examples: run commands over ssh
Get remote server date and time:
ssh user1@server1 date |
Find out remote server disk space usage:
ssh user1@server1 'df -H' |
Find out remote server kernel version and Linux distro names:
ssh root@nas01 uname -mrs |
OR
ssh root@nas01 lsb_release -a |
Sample session:
Run a script called /scripts/backup.sh:
ssh operator@oracle1 '/scripts/backup.sh' |
Run sudo or su command using the following syntax:
## sudo syntax ## ssh -t user@hostname sudo command ssh -t user@hostname 'sudo command1 arg1 arg2' ## su syntax ## ssh user@nas01 su -c "/path/to/command1 arg1 arg2" # RHEL/CentOS specific # ssh user@nas01 su --session-command="/path/to/command1 arg1 arg2" ssh vivek@nixcraft.home.server su --session-command="/sbin/service httpd restart" |

Typo with the lsb_release command. Where you have it as host, not command.
Thanks for the heads up. The faq has been updated.
how can I run/execute ‘nm-tool’ command remotely from the server on host through ssh protocol??
How to run in background over ssh ?
