EEM applet writing to a file on disk and multiple pipes

I have looked and cant figure out how to do the following in a EEM file. 

 

If i have a command just as, 

action 1.1 cli command "show platform software status control-processor brief | append bootflash:/rpcpu1min.txt"

How can i proceed this command with a header so when the EEM applet emails me the file i know what command was executed to obtain that result.  It would be great if i can just append/echo a command to the file before executing the above command. How can i accomplish this. 

 

Also it seems like EEM doesn't like more than one pipe | per command is there a way to use multiple pipes? for example the following command will not work with cli command with double pipes. 

 

sh proc cpu sort | in xxx | append bootflash:/rpcpu1min.txt

 

 

TIA, Paul

Hi there,

If I am understanding you right, why not assign the cli command to a variable and then reference it in the applet. Like:

action 0.1 set CMD01 "show platform software status control-processor brief | append bootflash:/rpcpu1min.txt"
action 1.1 cli command "$CMD01

...you can then use $CMD01 elsewhere.

 

cheers,

Seb.

Re: EEM applet writing to a file on disk and multiple pipes

problem is when you have multiple pipes in the command it doesnt work. 

 

show in desc | in something | append flash:/file name 

The above command doesnt seem to work with multiple pipes.

Hi Paul,

As you have discovered the function of the second pipe differs from what you expect in a UNIX terminal. The second pipe is actually an OR operator.

 

If you just want to write a string to a file outside of the action cli command statement, then you will need to assign the result to a variable and use the action file command. Something like this (untested!!) :

action 0.1 set CMD01 "show platform software status control-processor brief | append bootflash:/rpcpu1min.txt"
action 1.1 cli command "$CMD01"
action 1.2 file open fh flash:some_output.txt w
action 1.3 file write fh $_cli_result
action 1.4 file close fh

I don't have an IOS device nearby to test this on, so I look forward to hearing back from you :)

 

cheers,

Seb, Thank you I will test and post results to the group, reading the doc you sent me it should work.
