How to compare two text files for the same exact text using BASH Script?

Let's say I have two text files that I need to extract data out of. The text of the two files is as follows:

File1.txt

ami-1234567
ami-1234567654
ami-23456

File-2.txt

ami-1234567654
ami-23456
ami-2345678965

I want all the data of file2.txt which looks same from file1.txt.

Just another option:

$ comm -1 -2  <(sort file1.txt) <(sort file2.txt)

The options specify that "unique" limes from first file (-1) and second file (-2) should be omitted.

This is basically the same as

$ join <(sort file1.txt) <(sort file2.txt)

Note that the sorting in both examples happens without creating an intermediate temp file, if you don't want to bother creating one.

Did you try join?

join -o 0 File1.txt File2.txt

ami-1234567654
ami-23456

remark: For join to work correctly, it needs your files to be sorted, which seems to be the case with your sample.
