In Red Hat Linux, this is accomplished by adding a small script to the system’s profile.d directory. It is possible to edit existing files like bashrc but you may lose those changes when upgrading. I usually create a custom profile script that contains this as well as other global variables and place it at /etc/profile.d. For this post, we’ll create global-prof.sh and get this setup.
It’s best if you login or su as root before you begin.
Create the file for the script
Add this to the script
#!/bin/bash # Location of this script: /etc/profile.d/ # Purpose of script is to makes writing to .bash_history immediate shopt -s histappend PROMPT_COMMAND="history -a;$PROMPT_COMMAND" # End of script
Save the script and exit by typing
and press Enter. This writes and quits out of the vim editor.
Set permissions and ownership of file
chown root:root /etc/profile.d/global-prof.sh chmod 644 /etc/profile.d/global-prof.sh
Make the script executable
chmod +x /etc/profile.d/global-prof.sh
Log completely out, log back in, run a couple of commands (any commands like history, ls, etc.), and then check the history by running:
You should see the last couple of commands you just ran.
A quick break-down of the script itself
The first command changes the .bash_history file mode to append. And the second configures the ‘history -a’ command to be run at the shell. The ‘-a’ immediately writes the current/new lines to the .bash_history file.
