Hi
I have file whose name to be appended by a value in the same file

The value starts from the position 10 and ends at position 30 , this value is same in  the whole file. We have  to trim the spaces if it has any spaces at its end.
the file is fixed width file

example
filename:   test1

values in test1

abc       34rtst               kkkkdafdf
kfl         34rtst               kjdfada;lk
dfa        34rtst               adddfjadf

the file name should be renamed to test1_34rtst

or a non-perl solution

mv file1 file1_$(head -1 test1|cut -c10-30)

Note that because no quotes are used, any whitespace is automatically discarded.
