Hello,

This is not homework or school work. I'm a seasoned C++ developer on windows. My current project is both, windows and unix based. As part of my expanding job duties, I'm getting my feet wet in the unix world as well.

My problem is that I have a very large file called ColCheckMe which is tab-delimited, that I have to process. Each line in ColCheckMe has 7 columns, and the values in the 5th column are integers. Using shell functions (and standard LINUX/UNIX filters), I have to verify that these conditions are satisfied in ColCheckMe. In the same file, each value in column 1 is unique. How do I verify that? I have to write a shell function that counts the number of occurrences of the word “SpecStr” in the file ColCheckMe.

Thanks for any help.
