config directory, in stead,* if it exists*, then make sure config file is 
present with those info. Cheers!!

[Puppet Users] how to do conditional check?

[Sans]

Dear all,

This is my script in the bash: how can I put it into  puppet?

#!/usr/bin/env bash

CONF_DIR=/var/mom_priv
CPU_COUNT=`cat /proc/cpuinfo | grep siblings | uniq | cut -d\  -f2`

ideal_load_var=$(echo scale=2; ${CPU_COUNT}+0.5 | bc)
max_load_var=$(echo scale=2; ${CPU_COUNT}*1.2 | bc)

if [ -d ${CONF_DIR} ]; then
cat  EOF  ${CONF_DIR}/config
\$ideal_load ${ideal_load_var}
\$max_load ${max_load_var}
EOF
fi


All I wann do is: Get the CPU_COUNT and then if  CONF_DIR exists, make sure  
$CONF_DIR/config is present with the above lines. How should I write that 
for puppet? Cheers!!

I don't have a lot of time, but I can get you started.

Puppet way:
1) Create a File resource that creates the config directory.

2) Run facter at the command line and look for the name of the variable that 
tells how many processors the computer has.  That variable will exist when the 
catalog is compiled as a variable.

3) Use a template with File to create your config file.


Quicker way: (Not reccomended)
1) Copy that script to the computer using File.
2) Run the script using Exec.
