I’m a newb and super beginner in programming. I have some genomics data in the form of 3 files: .bed, .bim and .fam. Could someone please show me the code with PLINK in command line to transform the .bed file into a human readable text file like .txt or .csv ?
I don’t know how to write code in R or Python, so command line only. thanks a lot!

I tried several code that I found online, but it either pops out error notice “failed to open XX.bed” or “–bfile accepts at most 1 parameter”, I don’t know why
