@5taras I have changed it to: #!/usr/bin/env bash
This will fix your "redirection unexpected" error by making sure the script runs with bash, which supports the process substitution syntax you're using.
Please use the script with caution!
Useful script. I'd add localepurge too. I found also a useful ucaresystem-core app.

I updated the script to make it safer, and now you can be more selective about which folders you want to remove from the .cache
✅ Shebang line: Uses #!/usr/bin/env bash (already implemented)
✅ localepurge: Added with automatic installation prompt
✅ ucaresystem-core: Added with automatic installation prompt
What these tools do:
localepurge:
Removes unnecessary locale files (language packs)
Can free up significant space if you only use one or two languages
Automatically configures which locales to keep during installation
ucaresystem-core:
All-in-one Ubuntu maintenance tool
Performs: updates, removes old kernels, cleans apt cache, removes orphaned packages
Basically does many of the same tasks but in one command
The -u flag runs it in unattended mode
how can we fix this in localpurge can't navigate on clicking any button it shows thses character instead of navigating/selecting

This script is specifically designed for Ubuntu/Debian systems and uses Linux-specific commands that don't exist on macOS.
I am using a macos theme, this is Ubuntu 24.04 : )

Hi, thanks for reporting this issue!
I've identified the problem - the interactive localepurge dialog in Step #19 was causing the script to hang. I've updated the script to resolve this issue for now.
Fix: Step #19 has been replaced with:
# 19. Localepurge - Remove unnecessary locale files (SKIPPED)
progress "Skipping locale files cleanup"
if [ $DRY_RUN -eq 0 ]; then
echo "Localepurge step skipped to avoid interactive dialog"
echo "✓ Locale cleanup skipped"
fi
Thank you so much : )
