MQSeries.net :: View topic - Cmd Line editing and Cmd Recall for MQSC.....Updated

Well there isn't one, once you type runmqsc there is no command recall and the only editing option you have is the backspace and arrow keys but for the people running MQSeries on UNIX and to a certain extent DOS there are ways to issue MQSC commands and have command line editing and command recall.

On Unix platforms simply set your shell to ksh and set your editor to vi as in
# ksh
# set -o vi

Then use the following syntax:

# echo "dis ql (*) curdepth" | runmqsc QMGR01

Then if you want the output sent to a file:

# echo "dis ql (*) curdepth" | runmqsc QMGR01 > /tmp/disqlout
> will clobber an existing file with the new output
>> will abend to the end of an existing file

This allows you to use vi, view, more or cat to see the contents of the file file or save the output for later use.

If you don't recall the exact name of specific QL and you know a unique portion of the name of the object then:

# echo "dis ql (*)" | runmqsc QMGR01 | grep STRING

(note you can use this syntax in DOS to but don't use the quotes)
(note this will also allow you to imbed MQSC command in simple shell scripts)

If you want to know the number of running channels on QMGR01 then do this:

# echo "dis chs (*)" | runmqsc QMGR01 | grep -v grep | grep RUNNING | wc -l

(note do not use the "all" argument in the dis chs when running this or you will get a line count for all the MCASTAT instances of RUNNING doubling you total)

In Unix you can use Esc-k to recall the most recent command and edit it.
(note Esc-k is reading the .sh_history file)

Continue hitting k to move farther backward in the command history. You can use j to move forward.

(note in DOS us the up arrow to move backward and the down arrow to move forward in the command history but this only works in an existing DOS Command Window instance)

You can edit the command lines using normal vi commands like l to move left, h to move right, i to insert text etc.

(note in DOS use your arrow keys, delete and backspace and when typing changes keep in mind that you are alway in insert mode)

Also in Unix if you want to search your history hit Esc-K then / and type the string you are looking for. For example

# /ql

will find the most recent ql in you .sh_history. Then you can type n to get to the next instance of ql in your .sh_history.

I suppose if you wanted to use another Unix editor like Emacs you could but I prefer vi because it is included in almost if not all flavors of Unix.

Also, this works for regular Unix commands aswell. For example if you type

# ps -ef | gerp -v grep | grep mqm | wc -l > mqmproc.out

you will get an error "gerp not found"

Hit Esc-K, use the l to move left until the cursor is on the e in gerp and type xp. xp will switch the position of the e and the r so that gerp is grep then hit Enter.

When I was first exposed to these little tricks I didn't give them much credence. Then after time I started using them more and more often. Now I can't imagine not using them.

What is the curdepth now? How about now? Now? OK fine...

# while true
# do
# echo "dis ql(SYSTEM.DEAD.LETTER.QUEUE) CURDEPTH" | runmqsc MQMGR
# echo "dis ql(APP.QUEUE) CURDEPTH" | runmqsc MQMGR
# sleep 15
# clear
# done

Makes life easier for me so I thought I would share it.
