Concatenate only digits from a line of text 2

[pdtak]

How do you contenate numeric value from a line of text?
I need to store just the numbers into a valiable.
#!/bin/ksh
LINE="time_last_login=1220039866"
TIME=<<concatenated value after the "=">>
...
echo $TIME
1220039866

Thank you in advance.

Hi

Concatenate only digits from a line of text

Only to answer exactly to your subject :

echo "$LINE" | tr -cd '[[:digit:]]'

But personally I always use solutions like PDreyer's.
