Top Forums Shell Programming and Scripting Search for names in one list in another and print results Post 303020559 by RudiC on Monday 23rd of July 2018 07:32:30 AM

Welcome to the forum.

Please become accustomed to provide decent context info of your problem.

It is always helpful to carefully and detailedly phrase a request, and to support it with system info like OS and shell, related environment (variables, options), preferred tools, adequate (representative) sample input and desired output data and the logics connecting the two including your own attempts at a solution, and, if existent, system (error) messages verbatim, to avoid ambiguities and keep people from guessing.

What exactly is going wrong with your code snippet - after having added a semicolon in front of the do? And, except this being incredibly inefficient. When I run it, it gives me the file2 lines for the names in file1.

Did you consider sth. like
Code:
grep -ffile1 file2
STEVE     USER1    0987
BOB        USER3    9327
CRAIG     USER4     3427

?
