问题
I want to name each .tar file in the code below and name it based on a list-file that contains the names, but I don't want to mess with the exclusion tag. I have a list file and I was thinking of using a text editor and adding cvf to the beginning of each line I have in a list and then use sed to replace the string cvf, thus adding the flag and then the name follows.
i.e.
cvf name1
cvf name2
cvf name3
I tried using sed 's/cvf/word2/g' input.file and as expected it only replaces cvf with the replacement word. I want the replacement word (word2) to change and to be each line from a list file.
Code I want modified:
stage ('Zip Repo340') {
steps {
sh"""
tar --exclude='*.tar' -cvf .tar *
"""
stage ('Zip Repo341') {
steps {
sh"""
tar --exclude='*.tar' -cvf .tar *
"""
stage ('Zip Repo342') {
steps {
sh"""
tar --exclude='*.tar' -cvf .tar *
"""
I have 340 of these repositories and I want to name them based on a list file that I have.
List file:
name1
name2
name3
Desired output:
stage ('Zip Repo340') {
steps {
sh"""
tar --exclude='*.tar' -cvf name1.tar *
"""
stage ('Zip Repo341') {
steps {
sh"""
tar --exclude='*.tar' -cvf name2.tar *
"""
stage ('Zip Repo342') {
steps {
sh"""
tar --exclude='*.tar' -cvf name3.tar *
"""
I can add cvf to each line of my list file, but if there's a more elegant solution I'm all ears. The biggest issue I'm having is running the sed replacement command and have the replacement word come from a list file.

This'll do it. Assuming File_1.txt has your code and File_2.txt has the names to replace.
while IFS= read -r line; do
sed -i "0,/cvf \.tar/{s|cvf \.tar|cvf ${line}\.tar|}" File_1.txt
done < File_2.txt
What is happening here?
sed -i <gobledegook> File_1.txtWe are making changes to File_1.txt. What changes? Lets explore thesedscript that is the<gobledegook>"0,/<gobledegook>This says we will be searching for the first occurrence of something"0,/cvf \.tar/<gobledegook>That something that we will be searching for will becvf .tarWe had to say\.tarbecause.is a "special character""0,/cvf \.tar/{s|<gobledegook>}We are saying here that on the line that our search string exists we want to do another sed script. The new sed script is defined in{}I decided to use|as a delimiter for the second sed script to help distinguish the two."0,/cvf \.tar/{s|cvf \.tar|}We are going to replacecvf .tarwith something"0,/cvf \.tar/{s|cvf \.tar|cvf ${line}\.tar|}"We are going to replacecvf .tarwithcfv ${line}.tarwhere${line}is the current line fromFile_2.txt
Very similar to this problem

You could do something like:
SCRIPT_NAME='outScript.sh'
while read filename; do
# Replace only the first match:
sed "0,/-cvf \.tar/s/-cvf \.tar/-cvf ${filename}.tar/" $SCRIPT_NAME > /tmp/tmp.sh
mv /tmp/tmp.sh $SCRIPT_NAME
done < all_filenames.txt
Basically, you go through your names file, and for each name, you replace the first non-replaced match
