    <p>I am trying to connect the remote ssh server via ruby using Net::SSH.It is working fine for me for all the commands provided via script and i could able to read the output of the command successfully. But when i use the below command it is getting stuck in SSH.exec!(cmd) and control is not returned from the line. Only if i click Ctrl+c in command line the script is getting ended. The command is ./wcsadmin.sh start --> this is used to start the processes of my application in remote server</p> <p>Please find the below code snippet of my ruby script:</p> <pre><code>Net::SSH.start(host, username, :password =&gt; password) do |ssh| puts 'before exit' output = ssh.exec!(/opt/wcsadmin.sh start) puts 'Executed command' </code></pre> <p>The output of the command when i do it manually is :</p> <blockquote> <p>[root@test bin]# ./wcsadmin.sh start</p> <p>Starting Network Control System...</p> <p>This may take a few minutes... stty: standard input: Invalid argument</p> <p>Network Control System started successfully.</p> <p>Starting SAM daemon... Done. Starting DA daemon... Starting DA syslog daemon... start</p> </blockquote> <p>if i use ssh.exec('./wcsadmin.sh start') the only difference is the above output is getting printed but still the program is never ended.I need to manually end it by hitting ctrl+c. When i searched in google i could find you can use </p> <blockquote> <p>nohup command('nohup /opt/wcsadmin.sh start >/tmp/teststartserver.log 2>&amp;1') </p> </blockquote> <p>to skip the hangup signals and tried the same.This also writes the output to teststartserver.log but getting hanged.Can anyone please help me out on this issue?</p> <p>Thanks in Advance!</p> <p>Thanks, Meena</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
