For example I have 190 files and I want to add L001 in the middle. How can I do that using cmd command, or PowerShell if it is better? Also some numbers are 2 digits some are 1.
PP-SD01_S1_R1.fastq.gz PP-SD05_S1_R2.fastq.gz PP-SD09_S20_R1.fastq.gz PP-SD025_S20_R2.fastq.gz PP-SD039_S22_R1.fastq.gz PP-SD039_S22_R2.fastq.gz ... I want to add L001 on each one of them between S.. and ..R. For example PP-SD039_S22_L001_R1.fastq.gz
Just use a regex to match the S... and the R... parts then insert L001 between them

cmd commandthen it's probably off-topic here because cmd runs on Windows only
