To answer your previous post, yes, change q{>>} to q{>} as you have already discovered :-)

Regarding Solaris versus Linux, I work mostly on Solaris but occasionally port my scripts to Linux. I have never had problems when doing that so I don't really know what might be going wrong. Check the obvious like making sure you have the same data files and script on both systems. After that it is probably a case of scattering extra print statements through you script to check that the data you think you are working with is in reality what you expected.

Sorry I can't be of more help.

Cheers,
