How to export the function in ssh
Hi Gurus,

I have a requirment to use a function created in a script in another server within the script. Below is the sample script for reference

Code:
#/bin/bash

logs_gen () {
          XXXXXXXXXXX
          XXXXXXXXXXX
          XXXXXXXXXXX
}

for i in x y z; do # x y z are the server names
ssh -q ${i}<< EOF
logs_gen #Here it is giving errors while executing this function.. like command not found.
exit
EOF
done

Could anyone suggest on this how to export the variable pls?

Regards,
VRN

save the code below to a file such as remote_run.sh
Code:
#/bin/bash

logs_gen () {
          XXXXXXXXXXX
          XXXXXXXXXXX
          XXXXXXXXXXX
}

logs_gen

then just run the commands below
Code:
for i in x y z; do # x y z are the server names
      ssh -q ${i} "bash -s" <  remote_run.sh
done

what is the remote_run.sh?

Is that the script to execute the function?

Could you elaborate please?

Sorry... got your suggestion...

But can this not be possible within the script instead of creating another script?

It's impossible to invoke a local function over ssh, as the local function just not have been defined at the remote environment!

You have to do a workaround.

In the ssh command, copy your script to tmp & trigger from there.

It should be doable on the fly,but not nice :
Code:
ssh host "printf \"testing () {\n cp "'\$'1" "'\$'2" \n}\" > /tmp/func;. /tmp/func; testing /tmp/func /tmp/func.used"

thanks all for all of your updates on this.

Can it be possible to export the variable (not function) to the remoote location...?

For ex: I've defined a variable and exported it... can i use it after I do the ssh to another server also?

Could anyone let me know the way for this pls?

VRN...
