I want two string like

b= 20180911183706376446

Can Anyone please help me out?


If your shell supports "//" substitutions in variables you can use


(notice that "-" should be last and "]" should be first in the [...] range expression.

If not, you can use something like this:

set_trim(){ local IFS=[:-]; v=$1; set -- $2; IFS=; eval "$v=$*"; }
set_trim a "$a"
set_trim b "$b"

or, with sed (less efficient since it has to start an external program):

a=`echo $a | sed 's/[]:[-]//g'`
