Data Pattern matching & storing result in variable
Hi!
i'm trying to parse textfiles against a pattern and storing the result in a variable.
The strings i want to get are embraced by [" and "] and can occur several times in one line, so e.g.
Code:
some text ["i want this string"] anything else ["and this one too"] end

what i have so far:
Code:
#!/bin/bash
for f in $*
do
    exec 3<&0
    exec 0<$f
    while read line
    do
        S=`echo $line | sed -n '/\["\([^"]*\)"\]/p'`
        # do something with S
    done
done

but this code gets the whole lines!
i've also tried epxr, but then i only get the first match.

please, help me!

I think this example can help:
Code:
cat INPUTFILE
222
some text ["i want this string"] anything else ["and this one too"] end
1111
some text ["i want this string"] 
333

cat INPUTFILE | sed 's/\[/\n[/g; s/\]/]\n/g' | sed -n '/^\[\(.*\)\]$/ s//\1/p'
"i want this string"
"and this one too"
"i want this string"

PS It's "useful use of cat".
