I am trying to read the temperature from my Avalon which has the Avalon Firmware: 20170603

I'm using the command:

cgminer-api -o stats

It brings me a lot of information that I don´t need.

But I just need this values:

 Temp[29] TMax[80] Fan[5490]
 Temp[29] TMax[80] Fan[5490]

I tried with this two commands but they didn´t work

1.- cgminer-api stats | grep "^ *[temp_avg]"
2.- cgminer-api stats | grep temp

Try:

$ grep -oE 'Temp[^F]*Fan[[[:digit:]]+]' text
Temp[30] TMax[77] Fan[5430]
Temp[29] TMax[80] Fan[5490]

How it works

• -o tells grep to print only the matching text and not the rest of the line.




• -E tells grep to use extended regular expressions. (The default basic regular expressions are archaic.)



• 
  

  Temp[^F]*Fan[[[:digit:]]+]

  
  
  

  This regex matches any string that starts with Temp, followed by any number of characters that don't include F, followed by Fan followed by a literal [, followed by one or more digits, followed by a literal ].

  
  

Looks like the requested fields are the eighteenth, nineteenth, and twentieth fields as separated by whitespace, so:

$ awk ' print $18, $19, $20 ' /path/to/input
Temp[30] TMax[77] Fan[5430]

This works:

grep -o 'Temp[[^]]+] TMax[[^]]+] Fan[[^]]+]'

Search the input string for:
Temp[ Start with Temp and a literal [
[^]]+ Not a closing], several times +.
TMax[[^]]+] Fan[[^]]+] repeat with TMax and Fan.

And print only it: -o.

General purpose commandline tools like awk, grep and perl are commonly used for this kind of problems. The cut command is a minimalistic, purpose built tool for it:

cut -d -f 18,19,20
