How to delete all files except one starting with specific text in a folder using Bash?

Question

I want to delete all files except the one that starts with 'Hello_' in folder '/backup' using bash command. Can you provide me with the bash command that can do it?

Answer 1

To delete all files in the folder /backup/ except the ones starting with 'Hello_', you can use the following Bash command:

find /backup/ -type f ! -name 'Hello_*' -delete

• "find /backup/" searches in the /backup/ directory.
• "-type f" ensures only files (not directories) are targeted.
• ! -name 'Hello_*' excludes files that start with 'Hello_'.
• -delete deletes all files that do not match 'Hello_'.
