Hello,

I have several fastq files like this:

7097-TK273759-HiSeqShotgun_S9_R1_001.fastq.gz
7097-TK273759-HiSeqShotgun_S9_R2_001.fastq.gz
7097-TK273763-HiSeqShotgun_S10_R1_001.fastq.gz
7097-TK273763-HiSeqShotgun_S10_R2_001.fastq.gz
7097-TK273775_1-HiSeqShotgun_S14_R1_001.fastq.gz
7097-TK273775_1-HiSeqShotgun_S14_R2_001.fastq.gz
7097-TK273775_2-HiSeqShotgun_S15_R1_001.fastq.gz
7097-TK273775_2-HiSeqShotgun_S15_R2_001.fastq.gz

I want to rename like this:

TK273759_R1.fastq.gz
TK273759_R2.fastq.gz
TK273763_R1.fastq.gz
TK273763_R2.fastq.gz
TK273775_1_R1.fastq.gz
TK273775_1_R2.fastq.gz
TK273775_2_R1.fastq.gz

try below code in terminal:

for file in *.fastq.gz; do
    if [[ $file =~ 7097-([^-]+)-HiSeqShotgun_(S[0-9]+)_R([0-9]+)_001.fastq.gz ]]; then
        prefix="${BASH_REMATCH[1]}_R${BASH_REMATCH[3]}"
        suffix=".fastq.gz"
        mv "$file" "${prefix}${suffix}"
    fi
done

enter image description here

Renaming multiple files at once is something that comes up quite often. That's why it's better to be acquainted with tools that have such feature. Most of these renaming tasks are one of a kind so writing scripts and regexes might become cumbersome compare to creating a vim macro.

Terminal based file managers like nnn or ranger have a bulk renaming feature where you can edit the list of file names in your preferred editor like vim.

Also in emacs dired mode you can make your buffer writable and rename your files all at once.
