how to find numbers in string

[Guiseppe]

hi, I want find numbers in string. its simple task, but I need to find numbers bigger then 9 too. my english is quite bad so I give you example for understand: from string "a20b1++q140" script find numbers x[0]=20 x[1]=1 x[2]=140. can somebody help me with that?

Hi Giuseppe,

it would look to me that you've got the numbers already parsed. But what do you want to do with them?

I'd use bash built-in arrays and sed, e.g.:

#!/bin/bash
declare -a array
string="foo1bar2shite3blah4"
array=($(echo $string|sed -e 's/[^0-9]/ /g'))
echo Number of numbers found: ${#array[*]}
echo "first number:  ${array[0]}"
echo "second number: ${array[1]}"
echo "third number:  ${array[2]}"
echo "fourth number: ${array[3]}"
