SG SecureCRT OSC 3008 Fix – Ubuntu Terminal Prompt Cleanup

Short Summary

A lightweight Bash utility for Ubuntu servers that fixes the unwanted 08;start=...;machineid=...;type=command;cwd=... metadata appearing in SecureCRT terminal sessions.

The script safely disables the systemd OSC 3008 shell-context integration responsible for the unwanted terminal output, without modifying your normal Bash prompt, .bashrc, SSH configuration, or SecureCRT settings.

What Problem Does It Fix?

On newer Ubuntu and systemd versions, you may see terminal output similar to:

root@sanchit-client:~# hostname

08;start=...;machineid=...;user=root;hostname=sanchit-client;bootid=...;type=command;cwd=/rootsanchit-client

Instead of the expected:

root@sanchit-client:~# hostname

sanchit-client

The additional text is generated by systemd OSC 3008 shell-context signalling.

Some terminal clients may display this metadata instead of processing it as a terminal control sequence.

Key Features

• Ubuntu detection before making changes
• Detects systemd OSC 3008 shell integration
• Removes the active OSC 3008 profile integration
• Prevents the integration from being recreated automatically
• Does not modify PS1
• Does not modify .bashrc
• Does not modify SSH configuration
• Does not modify SecureCRT configuration
• Status-only verification mode
• Built-in restore option
• Conservative handling of existing configuration files
• No external dependencies
• No data collection or transmission

Download and Extract

unzip sg-securecrt-osc3008-fix-v1.0.0.zipncd sg-securecrt-osc3008-fix-v1.0.0

Run the Fix

Make the script executable:

chmod +x sg-securecrt-osc3008-fix.sh

Run it:

sudo ./sg-securecrt-osc3008-fix.sh

If already logged in as root:

./sg-securecrt-osc3008-fix.sh

Check Status Only

To inspect the server without applying changes:

sudo ./sg-securecrt-osc3008-fix.sh --status

Restore Original Behaviour

If a future SecureCRT or systemd update resolves the compatibility issue, the original configuration can be restored:

sudo ./sg-securecrt-osc3008-fix.sh --restore

Important – Reconnect After Running

The existing shell session may already have the OSC 3008 hooks loaded.

After the fix completes, run:

exit

Close the SecureCRT session completely and reconnect.

Then verify:

Expected result:

[sg_output]
root@sanchit-client:~# hostname
sanchit-client

root@sanchit-client:~# whoami
root

root@sanchit-client:~# echo “$TERM”
xterm-256color
[/sg_output]

The unwanted 08;start=... metadata should no longer be displayed.
