if matching strings in file1 and file2, add column from file1 to file2
I have very limited coding skills but I'm wondering if someone could help me with this. There are many threads about matching strings in two files, but I have no idea how to add a column from one file to another based on a matching string.
I'm looking to match column1 in file1 to the number following the string "Gene_" in file2. If there's a match, I want to add column 2 from file1 as the first column in file2.
