Alternativement, tu peux faire:

grep "2010-10-19" /var/log/asterisk/cdr-csv/Master.csv | awk 'BEGIN{FS=",\""} /ANSWERED/{split($11, a, "\""); split($12, b, "\"");printf ("%s,1\n%s,-1\n", a[1],b[1]); }' | sort | awk -F , '{cpt=cpt+$2; printf ("%s %01d\n", $1, cpt);}' | awk 'BEGIN {pdur=0;}{ if (pdur==0){pdur=substr($2,0,2)*60*60+substr($2,4,2) *60+substr($2,7,2); pc=$3; mcc=0;}else{ dur=substr($2,0,2)*60*60+substr($2,4,2)*60+substr( $2,7,2); d[pc] = d[pc]+dur-pdur; nc[pc]++; pdur=dur; pc=$3;} } END {for (i in d) { if (i>0) printf ("%d: Calls=%d, Min= %6.2f\n",i, nc[i],d[i]/60); }}'`
