How to bulk rename files in a directory?

Question

linux

Hello everyone! I again have one of the easiest questions over which I puzzle all day. I have a task here to make a script that will rename files in a specific directory:
File1
...
File5
For example:
File1_renamed
...
File5_renamed
I know that this can be done through suffix , but the catch is that as an example I was given a simple rename files with the addition of this renamed, and you need to do just that. I thought about listing the files and renaming them like this, but I have no idea how to do it so that the changes affect the names of the files themselves in the directory, and not just as output to the console.

Answer 1

find /var/www/ -type f -exec mv {} {}_renamed \;
find-recursive search from the given directory and below
/var/www- where to look, if in the current directory, then you can replace it with .
-type f- only files
-exec execute with found
mvmove
{}what is found in this case filename
\;- just end the command.
You can check this way, instead of renaming, you will just get a print of the commands themselves. Mark as solved, thanks cap.
find /var/www/ -type f -exec echo {} {}_renamed \;

Answer 2

rename -e 's/(.*)/$1_renamed/' *

Answer 3

there are many ways to rename, here are google examples Renaming files with find, sed and xargs
specifically in your case you can do this

ls -1 |awk '{print $0,$0"_renamed"}' | xargs -n2 mv

with spaces in the title

ls -1 |awk '{print "\""$0"\" \""$0"_renamed\""}' | xargs -n2 mv

Answer 4

Search keywords are "find with the -exec key", "regex", "mv".
