Hi RudiC


thank you kindly for the code it works nicely in normal linux arch but not in ARM arch


Code:

#!/bin/bash
 usage()
{

  echo "usage: sysinfo_page [[-f file ] | [-h]]"
}
  while [ "$1" != "" ]; do
    case $1 in 
       -f | --file )           shift
                                filename1=$1
                                ;;
        -h | --help )           usage
                                exit
                                ;;
        * )                     usage
                                exit 1
    esac
    shift
done
#cd /tmp/runfiles/tmp


awk -F, '
NR == 1         {$1 = "timestamp"
                 print
                 next
                }
                {cmd = "date +\"%F %T\" -d@" $1
                 cmd | getline $1
                 close (cmd)
                 $2 = $2 ".0"
                 if ($3) $3 = $3 ".0"
                }

under ARM I get invalid date whereas in X86_64 it works fine


how would I insert my above awk time shift into your code,, As I remember it was a bit of a bugger to get awk time to work correctly under ARM


awk 'BEGIN {FS=OFS=","}{$1=strftime("%Y-%m-%d %T",$1)

hi RudiiC
I modified your code slightly



Code:
 awk -F, 

' NR == 1         {$1 = "timestamp" 

                  print    

              next  
 
               } 

                {$1=strftime("%Y-%m-%d %T",$1)  

                $2 = $2 ".0"  

                if ($3) $3 = $3 ".0" 

                } 1 ' OFS=, file

now it works in both ARM and X86_64


and again thank you kindly for your help
