UNIX for Dummies Questions & Answers

Hello, I'm trying to take information from a list of hundreds of subject ids (where each line is a new subject id), and insert each line into a new text file that contains the pathnames for each subject.

To clarify, all subject have a similiar path name (e.g., C:\data\SUBJECT_ID\) that contains .img and .txt files for each subject. I want unix to create a new text file with 3 columns: the path to the subject's text file, the path to the subject's image file, and the subject id. After searching for some solutations, I have tried using a foreach loop to read each subject id from the id list, and insert each id name into the three columns of the new text file. Here's what I have been playing with:

Code:

foreach dir ( 'subjectlist.txt' )
echo
c:/data/$dir/$dir"g7.img" c:/data/$dir/mask.txt $dir > newfile.txt
end

This returns the subject ids, followed by "command not found". Essentially, I want to replace $dir with the subject id for everybody.

Please let me know if this isn't clear, I'm very new to unix and have been stuck on this for days, and I'd greatly appreciate any help!!

Please use code tags next time for your code and data. Thanks

What shell and OS you are talking about because here it looks like DOS...

I'm using csh in linux.

Didnt fully understand your question , the solution is built on guesses

Code:

 
cat test8
sub1
sub2
sub3
 
awk -v pathvar1="C:/data" '{ print pathvar1"/"$0"/"$0".img""\t"pathvar1"/"$0"/"$0".txt""\t"$0}' test8
C:/data/sub1/sub1.img C:/data/sub1/sub1.txt sub1
C:/data/sub2/sub2.img C:/data/sub2/sub2.txt sub2
C:/data/sub3/sub3.img C:/data/sub3/sub3.txt sub3

Thanks for the suggestions. I wasn't able to get it to work right with awk, but I finally got it to work with a while loop:

Code:

while read line;
do echo c:/data/$line/$line"g7.img" c:/data/$line/tmask.txt $line; done < subjectlist.txt > subjectfilepaths.txt
