How To Remove Duplicates

[Louisbuitton]

I have duplicates like dis for example Fix_library_permissions.sh.3: line7: syntax error near unexpected token 'newline'
Fix_library_permissions.sh.3: line 7: `'

How do I remove duplicates like above ... .sh.3,
....sh.4, etc?

Make sure you’re running the right file, you seem to have duplicate files... Fix_library_permissions.sh.3

The file does not end with .3, I think its not a syntax error with the code I think you have multiple downloads of it

[Louisbuitton]

How do I delete these multiple download duplicates?

Still can't launch the browser and other apps after installing v5.1

[Louisbuitton]

$ mount l grep /dev/shm
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev,inode64)

$ sudo sed -i 's/dev,nosuid,noexec/nodev,nosuid/' /etc/fstab
Sudo password for noname:

Sudo mount -o remount /dev/shm
Mount: (hint) your fstab has been modified, but systemd still uses the old version; use 'systemctl daemon-reload' to reload.

Systemctl daemon-reload'
Reload daemon failed: Method call timed out

Sudo ./fix_library_permissions.sh
./fix_library_permissions.sh: 8: Syntax error: newline unexpected
FAIL: 2

The above is the errors

this is indeed most likely user error, but there are also some script improvements I will upload an update now

What are the possible user errors?

1. About the “.sh.3 / .sh.4” files
   Those files are not created by this repo or by the scripts. They are almost always created by your browser / file manager when the same filename is downloaded multiple times (it appends .1, .2, .3, etc.).

To remove them, go to the folder where they exist and run:
ls -la fix_library_permissions.sh*
rm -- fix_library_permissions.sh.[0-9]*

(Or delete specific ones: rm -- fix_library_permissions.sh.3 fix_library_permissions.sh.4)

2. Why you are seeing: “Syntax error: newline unexpected”
   That message typically means one of the following:

• You are not running the file you think you are (for example you are executing a duplicate like “Fix_library_permissions.sh.3”, or running a copy from a different directory).

• The file contents were corrupted/modified during download or copy/paste. Your earlier error showing a stray single quote on a specific line is a strong indicator the script file you ran is not identical to the repo version.

• The script is being interpreted by /bin/sh (dash) instead of bash. This script uses bash-only syntax, so run it explicitly with bash:

  sudo bash ./fix_library_permissions.sh

Quick sanity checks you can paste back here:
pwd
ls -la fix_library_permissions.sh*
head -n 20 fix_library_permissions.sh
file fix_library_permissions.sh
bash -n fix_library_permissions.sh

3. About /dev/shm and /etc/fstab
   Your mount output shows /dev/shm is already mounted without “noexec”, which is the browser-compatible state. Editing /etc/fstab by hand is easy to get wrong; duplicate or malformed entries can also cause systemd operations like “systemctl daemon-reload” to hang or time out.

If browsers and apps still won’t launch after v5.1, please open a separate issue and include the full output of:
sudo bash PERM_diagnostic.sh
sudo bash verify_fortress.sh
Plus your distro/version and whether this is a desktop or server install.

Again, this is not an issue with the software, you are asking for tech support some of which is unrelated to my project, please refer to the readme.MD for anything relevant to this.
