I want to search MU Ids of file 1 in file 2 and then add the corresponding 1stcolumn and 2nd column.

expected output-

It is a sample file the original file is very large so I cant do it manually. I have tried Rscript-

df <- merge(df1, df2, by.x = "MU_Id", by.y = "MU_Id")

But I got output like this-

With grep you can achieve the same.

grep -Fxf is the way to go, as long as OP knows what they're doing and the edge cases where it could fail.

I have tried Rscript-

This is most uninformative, please show some effort.

What is the output you get?

We cannot read your screen or your mind. You'll have to explain more. Don't make this too hard for us or you won't get any help.

That is not possible - your output does not have V1-style headers, but has proper headers. Either your command is wrong or your output is.

Did you read the help page? ?merge

Play around with the optional arguments.

Perhaps this could work for you:

merge(df1[!duplicated(df1$MU_Id), , drop=FALSE], df2, by = "MU_Id", all.x = TRUE, all.y = FALSE)

If you actually want the duplicates in df1, then:

merge(df1, df2, by = "MU_Id", all.x = TRUE, all.y = FALSE)

You don't need to add all.y=FALSE, it's programmed to be set to FALSE unless you explicitly set it to TRUE

> ?merge

## S3 method for class 'data.frame'
merge(x, y, by = intersect(names(x), names(y)),
      by.x = by, by.y = by, all = FALSE, all.x = all, all.y = all,
      sort = TRUE, suffixes = c(".x",".y"), no.dups = TRUE,
      incomparables = NULL, ...)
