Hello,
I thought I understood the magenta pattern but not.

I have understood this line with the commande echo

Code:
$z_cat $log_name |awk -F"[/ \\\][]" -v S="24/01/2013 10:10" -v E="24/01/2013 10:30"

Code:
echo "[24/01/2013 10:10 10:51]" | awk -F"[/ \\\][]" '{ print FS ; print $2; print $3; print $4; print $5; }'
[/ \][]
24
01
2013
10:10

Code:
#!/bin/bash
log_name=$1
if [[ "$log_name" =~ .gz$ ]]
     then z_cat="gunzip -c"
     else z_cat=cat
fi
$z_cat $log_name |awk -F"[/ \\\][]" -v S="24/01/2013 10:10" -v E="24/01/2013 10:30" '
function dcmp(b) {
  if($4>b[3])return  1;
  if($4<b[3])return -1;
  if($3>b[2])return  1;
  if($3<b[2])return -1;
  if($2>b[1])return  1;
  if($2<b[1])return -1;
  if($5>b[4])return  1;
  if($5<b[4])return -1;
  return 0;
}
BEGIN{split(S, ds, "[/ ]"); split(E, de, "[/ ]") }
/^[[][0-9][0-9]\/[0-1][0-9]\/[[0-9][0-9][0-9][0-9] / {
   if(s&&dcmp(de)>=0) {print; exit}
   if(!s&&dcmp(ds)<=0) {f=x;w=1}
   if(!s&&dcmp(ds)>=0) {printf "%s",f; f=x; s=1 }
}
!w&&!s {f=f $0 "\n"}
s'

What do these lines match ?

Code:
b[1]
b[2]
b[3]
b[4]
b[5]

Thanks in advance.
