[NTLUG:Discuss] change words on every line in a file

[o k]

Fred and all,
Sorry for confusion, the context (file) will be:
These is only 2 columns per line. space between 2 values can be change to desired space. (one space, 2 spaces... or tab)the first column is all different animal names.the second will be all same string. and I want to change them one line by one line through loop.$s2 value (was 1234)  should be replaced to $v (9899) -> after changed, second: v='9899', s2='9899'
Still looking for help.  Thanks.
