How can I remove these parts of my filenames?

I have some files I need to rename in bulk. For example:

Jul-0961_S7_R2_001.fastq.gz    
Jul-0967_S22_rep1_R1.fastq.gz  
Jul-0974_S32_R2_001.fastq.gz

I need to remove the S* part of the filename but I don't know the right regular regex to use.

Specifically:

Jul-0961_S7_R2_001.fastq.gz --> Jul-0961_R2_001.fastq.gz

Something like, rename 's/S*//' *.gz is what I'm looking for.

Is there a regex wizard out there who can show me the way? Thanks in advance.

If the files are in the same format (i.e have the same number of underscores, you could use:

"ls" | awk -F_ '{ system("mv "$0" "$1"_"$3"_"$4) }'

Here we are using underscore as the delimiter and then building a command to execute with the system function

You should be able to use something like this: s/_S[0-9]+_/_/
