Linux Command Error for nawk command

Hi All

We are migrating our projects from unix environment to linux. I tried running a install script which sets up my project, i.e. the directory structure and all. But in the middle of the script i started receiveing following error : nawk: command not found .

So i need to know which command can i use in linux which will do the same job as nawk does, Is it gawk or something else if you all can suggest.

Many Thanks

awk should suffice!
