I have to remove ".1.3" from the string.

Jouher_20929

'hello.A  at  strain rate:=1000.235 per milli-second.1.3' Consider this string. I have to remove '.1.3' from last word of string and give whole string back. It should be generic. That is, from last word i have to remove every characters after '.' [including '.']

Hi,

if the last word of STR is 'second' :

set STR [string range $STR 0 [string last second $STR]+5]

 

or 

regsub second.* $STR second STR
