Right... I tried it on Solaris. But I used the version installed as /usr/xpg4/bin/awk, that is, nawk. Don't know why it didn't give the result.

Yeah both namk and mawk left me cold for the sorts of things they have chosen to not support. In your case I would probably ditch the if all together as it is not really testing anything and just perform
the assignment and the print:

Code:

awk '{$5="chr"$5;print}' file

Should hopefully work

Have you got/can you install sfw (sun freeware pkg)? That has the GNU toolset

Usually goes in /opt iirc.
