Renaming file in same directory -Shell Script

Question

I have an array with name VERSION that I take from mydir directory and it has parameters(files) as below:

VERSION[0]="TEST01_0.TEST01_1"
VERSION[1]="TEST03_1"
VERSION[2]="TEST02_1.TEST02_2"
VERSION[3]="TEST04_2"
VERSION[4]="TEST02_3"

And I was trying to rename TEST01_0.TEST01_1 as TEST01_1 and TEST02_1.TEST02_2 as TEST02_2.But I am getting some error as below:

mv: cannot stat `TEST01_0.TEST01_1': No such file or directory
mv: cannot stat `TEST02_1.TEST02_2': No such file or directory

Can you please help me to fix it? Here is my code block:

#!/bin/sh
VERSION=(/mydir/TEST*)
for file in "${VERSION[@]}"
do
    if [[ `echo ${file} | grep -o '_' | wc -l` == 2 ]]; then
    mv "${file}" "${file%.*}";
    fi
done

Thanks

I save it as test.sh and copy it to the lab then run the bash test.sh — Oscar Sayin

@OscarSayin: Can you run the script after navigating to mydir? — Inian

You say VERSION has TEST01_0.TEST01_1, TEST03_1, etc., but VERSION=(/mydir/TEST*) will mean it has /mydir/TEST01_0.TEST01_0, /mydir/TEST03_01, etc. Even so, the files should exist. Is this actually what you're running? What does bash -x test.sh output? — muru

These files are already in /mydir. I just want to rename the file name which has two '_' characters as their last part of the original names. I mean I want to see my array elemenst like:VERSION[0]=".TEST01_1" VERSION[1]="TEST03_1" VERSION[2]="TEST02_2" VERSION[3]="TEST04_2" VERSION[4]="TEST02_3" — Oscar Sayin

The best way for this would be to run from inside mydir with bash as below and not relying on any third party utilities like cut or grep

#!/bin/bash

for file in T*
do 
    # Getting the string only containing '_' and if the count matches, 2
    # doing the file rename

    dashes="${file//[^\_]/}"
    if (( "${#dashes}" == 2 ))
    then 
        mv -v "$file" "${file%.*}"
    fi
done

can I ask you more question? How can I rename file from Upgrade.TEST01_0.TEST01_1.sql to Upgrade.TEST01_1.sql. I want to remove TEST01_0 from file name. I have tried like mv -v "${file}" "${file##upgradeDb.*.}" but it didnt work.

Is it always after first two dots from beginning, i.e. skippping Upgrade and TEST01_0

@OscarSayin: It might need a proper regex, can you post it as a new question with your attempt, I will try and quickly answer it
