Change the text in 2nd column in file
Legends,

I have following entries in a file.
I want to toggle the entry of 2nd column. TRUE/FALSE
i tried using
Code:
perl -p -i -e

but the problem is, if instead of "tab" space after 1st column, there is a character or multi character space then this won't work.

Code:
perl -p -i -e "s/$i.xxx.out.remoteOn           TRUE/$i.xxx.out.remoteOn           FALSE/g" /tmp/file_a

Entries in the below file is like:

Code:
abc.xxx.out.remoteOn           TRUE                               write
def.xxx.out.remoteOn           TRUE                               write
ghi.xxx.out.remoteOn           TRUE                               write
jkl.xxx.out.remoteOn           TRUE                               write

Pls help, if i can use any other editor "sed", "awk" etc.(but i am not too familiar with these)

Regards
