Merges given files line by line

paste -d ',:' file1 file2 file3
In the above example all files have 4 lines. In "file1" consecutive lines are: "num, 1, 2, 3", in "file2": "name, Jack, Jim, Frank" and in "file3": "scores, 1300, 1100, 980". This one liner can save considerate ammount of time when you're trying to process serious portions of data. "-d" option allows one to set series of characters to be used as separators between data originating from given files.
Sample Output
num,name:scores
1,Jack:1300
2,Tim:1100
3,Frank:980

What Others Think

That's a handy dandy command. :-) It is also possible to do a two file merge using sdiff and a little "data transforming" with sed/awk.

True, true? :) Could you prepare awk alternative? It would be very nice to have one here.

does anybody know how to merge stdout lines? e.g. say I want to make my new version of ls that shows file and permissions (like a shorted ls -l). It would look something like this: ls -l |cut -c1-10 >/tmp/file1; ls -1 >/tmp/file2; paste /tmp/file{1,2} It's not just for the above example, but other stuff I have swirling in my mind.

How about using stat -c "%A %n" * in this particular case? ?stat? is more powerful than that.

One more thing about "paste". It can take "-" instead of file name. This makes "paste" to read lines from stdin. Nice thing here is that you can use more that one "-"s. For example if you've got file: author Shakespeare title Hamlet You can do cat file | paste - - to transform it into author Shakespeare title Hamlet

What do you think?

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
