Dear friends We are on rhel4.4 .when I am using the join command the syntex is not under stood by me .Can anyone explain ?? I want to join file1 on field 1 with file2 on field 1 with output required is 1,2,3,4,5 fileds of file2 . I have exprimented with [b]join -1 1 -2 1 -o 2.1 2.2 2.3 2.4 2.5 file1 file2 > filenew [/b] But could not succeed . Thanks in advance.

I'm not sure what you are trying to do exactly, but the output specifier needs to be either quoted or comma separated. join -1 1 -2 1 -o '2.1 2.2 2.3 2.4 2.5' file1 file2 > filenew join -1 1 -2 1 -o 2.1,2.2,2.3,2.4,2.5 file1 file2 > filenew
