awk problem
I am trying to use this awk command as filter:

Code:
 awk '/:Temperature/{printf "%s ", $2}'

if I run it from bash, there is no error.
however if running from script, I get this error:

awk: syntax error near line 1
awk: illegal statement near line 1


the problem seems to be in space character after the %s
how to correct it?
thanks

Code:
nawk '/:Temperature/{printf "%s\ ", $2}'

Your command lack an input (from a file or a pipe) otherwise, the BEGIN clause should be used.

I am curious to see how you ran your script from command line and what it does contain.

(also curious to see what was the input)

oh, ok.
that was a part of pipe.
input was from this command:
Code:
prtpicl -v -c temperature-sensor

I couldn't use that other command for temperature, as it only displays ok/fail in Solaris10.
(hopefully) the output is CPU and server temperature. should be in Celsius?
the plan is to run it in cronjob once per day. so I will see if temperature rises suddenly. it will tell us if one of the CPU fans has failed.

the 3 wire fans are impossible to obtain. also Sun used to sell only heatsink+fans combo, which cost a lot. yes, it is small compared to the price of server, but buying anything is complicated here.

Could you show us how the result of
prtpicl -v -c temperature-sensor
look like ?

here it is:
Code:
  mb_p0_t_core (temperature-sensor, 760000072a)
  :_fru_parent   (760000062fH) 
  :Label         T_CORE 
  :HighPowerOffThreshold         100 
  :HighShutdownThreshold         93 
  :HighWarningThreshold  88 
  :Temperature   50 
  :_class        temperature-sensor 
  :name  mb_p0_t_core 
  mb_t_enc (temperature-sensor, 7600000732)
  :_fru_parent   (7600000611H) 
  :Label         T_ENC 
  :HighPowerOffThreshold         51 
  :HighShutdownThreshold         48 
  :HighWarningThreshold  40 
  :LowPowerOffThreshold  -6 
  :LowShutdownThreshold  -3 
  :LowWarningThreshold   5 
  :Temperature   28 
  :_class        temperature-sensor 
  :name  mb_t_enc


edit:
btw, can someone help me with the script to compare the temperature with previous and output message if the difference is more than 3 deg?

Are you checking the temperature only once per day ?

yes, only once per day.
should we do it per hour?
