Rename the files by ignoring every thing after first space in file name

Question

I need to rename all the files in a directory like below:

Original file name: ABC_DEFGHIJK_LMNO Thu Jul 30 07:29:14 CEST 2020

Renamed file name: ABC_DEFGHIJK_LMNO

So basically I need to ignore every thing after first space while renaming the file.

Answer 1

You can write a simple bash script like this:

#!/bin/bash

cd /path/to/files
for f in *
do
  new_name=$(echo "$f" | cut -d ' ' -f1)
  echo renaming file "$f" to "$new_name"
  # mv "$f" "$new_name"
done

If the output is alright, uncomment the mv command to rename the files.
