I have an adapter code which executes some specific commands on a Linux machine via SSH. It executes commands and handles the output of each command in a specified manner.
The issue being faced is very straightforward.
I am connecting to a Bash prompt that uses colors. Here are the details of the PS1 variable:
PS1="\[\033[1;34m\][\$(date +%H%M)][\u@\h:\w]$\[^[[0m}\]"
The code uses regex which decides a valid terminal first and then proceeds with the commands.
For example, .*\$ is considered valid
I can't seem to handle [^[[0m} properly and code is not able to identify the terminal as a valid one. If I remove it from PS1 variable, things work fine.
Can anyone please suggest what regular expressions might be entered so that the code takes it as a valid terminal?
I think the PS1 variable you provided above is broken.
I ran the following experiment in my terminal window:
[guest@localhost ~] $ export PS1="\\[\033[1;34m\\][\$(date +%H%M)][\u@\h:\w]$\\[^[[0m}\\]"
[2137][guest@localhost:~]$^[[0m}
As you can see ^[[0m} is not interpreted properly. I assume it is the end of the color in the prompt. I think it should be \\[\033[0m\\].
Here is the whole PS1 variable:
PS1="\\[\033[1;34m\\][\$(date +%H%M)][\u@\h:\w]$\\[\033[0m\\]"
After testing it you get this:
[2137][guest@localhost:~]$^[[0m}export PS1="\\[\033[1;34m\\][\$(date +%H%M)][\u@\h:\w]$\\[\033[0m\\]"
[2139][guest@localhost:~]$
