Operation Method of Batch Adding File Prefix in linux

Need to add "gt_" before the file name of all txt files in the folder;

That is, from the original file "xxx. txt" to "gt_xxx. txt":

The scripts searched online are as follows:

for i in `ls`;
do mv -f $i 'echo "gt_"$i`;
done

1. First, the linux command line switches to the directory where you need to modify the file name:

cd Destination Directory

2. Create a new sh file in this directory:

touch xxx.sh

3. Open the xxx. sh file:

vim xxx.sh

3. Copy the script content to the sh file, save and exit

Edit sh file: Shift+I

Save exit after pasting: Ctrl+Alt + D Exit edit status, then enter: wq! Quit

Execute the sh file:./xxx. sh

I haven't touched the instructions of linux before, but now I need to use some, so I take notes as a memo ~ ~ ~

ps: Batch change file prefix command under linux

for f in * ; do mv -- "$f" "PRE_$f" ; done
