Overview

If you need to collect large outputs of qshell commands, you can use the following procedure to redirect the output to a separate file, making it much easier to read.

Procedure

To redirect Qshell output to a separate file:

 

1. Log into the management controller node as root.

2. Exit out of OSMI by entering 0 (zero). 

3. Enter the following to print a list of namespaces and their details:

# qshell -c "print q.dss.manage.listNameSpaces()" | sed -e 's/, /\n/g'

 

4. Redirect the output to a separate file:

# qshell -c "print q.dss.manage.listNameSpaces()" | sed -e 's/, /\n/g' > /output_file.txt

 

 

5. Reformat the output so it's easier to read:

# echo "q.dss.manage.listNameSpaces()" | qshell > output_file.txt

 

Note: This is only one example of how to reformat the output. Pulling Qshell output and directing into a separate file may require some trial and error to figure out what works best.

 

6. View the output file:

# ls

# more output_file.txt

 

The informaton in the output displays:
