Extract numbers from output file and compare to value
Hi,

I developed a script which finally originates a similar output:

Code:
net0:up,Tx=475198bps,Rx=31009bps net1:up,Tx=39596bps,Rx=35678bps

Of course the figures change and also the amount of interfaces (ex: could be more then net0 and net1). This is done automatically.

The next step i'm trying to achieve is to extract these figures and compare them with a value. if the figures are larger then the value then i originate an output like:

Code:
net0 Tx is higher then the threshold

However i cannot understand how to make the script intelligent enough to output which receive is (transmit OR receive is higher then the threshold specified AND also which interface or interfaces

I tried to use the for loop like:

Code:
TX=`sed 's/:up//g' test.txt | sed 's/bps//g' | awk -F',' '{print$2}' | cut -c4-`
RX=`sed 's/:up//g' test.txt | sed 's/bps//g' | awk -F',' '{print$3}' | cut -c4-`

for tx in $TX
do
if [[ $tx -gt 9 ]]; then
INT=`grep $tx test.txt | awk -F',' '{print$1}' | cut -f1 -d":"`
echo -n "$INT tx is higher then usual "
fi
done

for rx in $RX
do
if [[ $rx -ge 0 ]]; then
INT=`grep $rx test.txt | awk -F',' '{print$1}' | cut -f1 -d":"`
echo -n "$INT rx is higher then usual "
fi
done

But with this scenario i cannot make an efficient output that i might know that for example both Tx/Rx are high or one of the interfaces has a high Tx.
What i'm trying to achieve is an output similar to this:

Code:
The following interfaces has high Tx usage: net0

Code:
The following interfaces has both high Tx/Rx usage: net0 net1

The script developed is in bash.

Could you kindly give me some hints?

Rgds,

Matthew

locale::codes::langfam

Locale::Codes::LangFam(3)				User Contributed Perl Documentation				 Locale::Codes::LangFam(3)

NAME

       Locale::Codes::LangFam - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangFam;

	  $lext = code2langfam('apa');		       # $lext gets 'Apache languages'
	  $code = langfam2code('Apache languages');    # $code gets 'apa'

	  @codes   = all_langfam_codes();
	  @names   = all_langfam_names();

DESCRIPTION

       The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in
       ISO 639-5.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5
       language family codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a
       constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lext = code2langfam('apa','alpha');
	  $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages.

	   This is the default code set.

ROUTINES

       code2langfam ( CODE [,CODESET] )
       langfam2code ( NAME [,CODESET] )
       langfam_code2code ( CODE ,CODESET ,CODESET2 )
       all_langfam_codes ( [CODESET] )
       all_langfam_names ( [CODESET] )
       Locale::Codes::LangFam::rename_langfam  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangFam::add_langfam  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangFam::delete_langfam  ( CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangFam::delete_langfam_alias  ( NAME )
       Locale::Codes::LangFam::rename_langfam_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::delete_langfam_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
