Searching for 'stanza1' will return
Code:
[stanza1]
id1: value1
id2: value2
id3: value3
[stanza12]
id1: value1
id2: value2
id3: value3

as a single result.
I would like to access to the content of each stanza, so that I could assign
Code:
[stanza1]
id1: value1
id2: value2
id3: value3

to, e.g., variable i, and
Code:
[stanza12]
id1: value1
id2: value2
id3: value3

to variable j.

Thanks for the reply ygemici, but this will cycle throug each line of the result, that's not what I need.
Code:
# cat infile
[stanza1]
id1: value1
id2: value2
id3: value3

[stanza2]
id4: value1
id5: value2
id6: value3

[stanza12]
id7: value1
id8: value2
id9: value3

Code:
# ./justdoit infile
Please enter variable name with counts "3" [eg -> i j k l m n..] i j k
'i' value= "[stanza1]
id1: value1
id2: value2
id3: value3"

'j' value= "[stanza2]
id4: value1
id5: value2
id6: value3"

'k' value= "[stanza12]
id7: value1
id8: value2
id9: value3"

Code:
#!/bin/bash
c=$(awk 'BEGIN{j=1}/[stanza.*]/{a[x++]=$0;while(getline){if(!/^$/)a[x++]=$0;
else{system(">"FILENAME "_"j);for(i=0;i<x;i++){print a[i]>>(FILENAME "_"j)};x=0;j++}}}
END{system(">"FILENAME "_"j);for(i=0;i<x;i++)print a[i]>>(FILENAME "_"j);print j}' $1)
read -p "Please enter variable name with counts \"$c\" [eg -> i j k l m n..] " val;rval=($val)
for((k=1;k<=$c;k++));do val[k]=$(echo "$(<$1_$k)")
echo -e  "'${rval[i++]}' value= \"${val[k]}\"\n";done
