Question

I have 8 files that need to be merged into one text file, with each of the file names being on a separate line.

The output should be as follows:

file.txt:

output1/transcripts.gtf
output2/transcripts.gtf
output3/transcripts.gtf 

and so on…

I have read several other suggestions and I know it should be an easy fix. I have tried dir and awk but have only gotten results that has all files in one line. I am using unix.

Answer 1

How about this?

 ls -1 output*/*.gtf > file.txt

or if the nesting of you sub directories is deeper and you want all files with names ending in “.gtf”:

 find . -type f -name "*.gtf" -print | cut -b 3- > file.txt
