Hello, I am trying to save multiple files containing SNPs at different chr positions. I run this command on my folder
ls -1v 192_imputed_*.bcf
The output is below, but as you can see 192_imputed_1_1_4516141.bcf is way below the list and it needs to be first, since it contains chr1 at position 1 to 4516141. I think this command is not considering the number of digits.
Any recommendation on how to run this?
Output when running ls -1v 192_imputed_*.bcf:

Run the output through a sort if the file order matters to you:
/bin/ls -1v *.bcf | sort -t_ -k1,1n -k3,3n -k4,4n -k 5,5n
There might be a better way to write that command though.
EDIT: From the -v, I'm assuming you're trying to leverage GNU ls -v natural sort. If that's the case, ensure you're using GNU ls indeed GNU ls by using man ls. On my mac
$ man ls | grep -- '-v'
-v Force unedited printing of non-graphic characters; this is the
$ which gls
/opt/homebrew/bin/gls #This is my homebrew-installed GNU ls
$ man gls | grep -- '-v'
version (-v), extension (-X), width
-v natural sort of (version) numbers within text
--version
See how my ls has a different -v option than my GNU ls? You might be in a similar situation as well
$ ls -1v | head
