shell: how to take part of the line...
How can i take part of text out of it....? (can't really express my self)
1) Lets say i want to get last/first 5 characters of text...
2) 3 characters starting from 4th character.....
In basic language there is function mid$(string$, offest%, lenght%)
what would be similar function in sh?
Also how can i determine how long is text line? ( len(string$) in basic)
