Top Forums Shell Programming and Scripting Two questions about my script : apply to all my csv and recover filename ? Post 303036691 by MadeInGermany on Monday 8th of July 2019 07:42:24 AM

Most efficient with awk:
Code:
awk -F, 'p1!=$1 { print "\nFRAME :", p1=$1i, "=====" } { print "\nRAM :", $2; for (i=3; i<=NF; i++) print "CPU ", i-2, ":", $i }'  *.csv

The same can be done with shell:
Code:
#!/bin/bash
pframe=
# loop over my arguments
for arg
do
  while IFS=, read -a col
  do
    if [[ $col != $pframe ]]
    then
      pframe=$col
      echo "
FRAME : $col ========================================"
    fi
    echo "
RAM : ${col[1]}"
    for ((i=2; i<${#col[@]}; i++))
    do
      echo "CPU $((i-1)) : ${col[i]}"
    done
  done <"$arg" #while
done #for
