“gnome-terminal”的标题在 Ubuntu 中被 .bashrc 覆盖

Question

I need to open around 20 terminals on the same time and execute different command on each one ,and I'd like also to name each window with a different name.

I'm using something as follows:

gnome-terminal --title="some title goes here" -- bash -ic "ls; exec bash"

The new window is opened , shows the title some title goes here and after 1~2 seconds it's being overridden and turns into the path that I'm running the command

 gnome-terminal --title="some title goes here" -- bash -ic "ls; exec bash"

from.

Here is my .bashrc :

# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples

# If not running interactively, don't do anything
case $- in
    *i*) ;;
      *) return;;
esac

# don't put duplicate lines or lines starting with space in the history.
# See bash(1) for more options
HISTCONTROL=ignoreboth

# append to the history file, don't overwrite it
shopt -s histappend

# for setting history length see HISTSIZE and HISTFILESIZE in bash(1)
HISTSIZE=1000
HISTFILESIZE=2000

# check the window size after each command and, if necessary,
# update the values of LINES and COLUMNS.
shopt -s checkwinsize

# If set, the pattern "**" used in a pathname expansion context will
# match all files and zero or more directories and subdirectories.
#shopt -s globstar

Any idea how to fix this ?

Answer 1

The prompt set in PS1 contains screen control codes which overwrite the window title.

If you don't want the prompt to change your window title, take out the snippet which does that.

Here's a slight edit to let you set no_title_change in the calling shell. This would replace the similar snippet in your current .bashrc ; the real change it that we change the variable $TERM to a slightly more complex (and slightly hacky) parameter expansion .

...

# If this is an xterm set the title to user@host:dir
# unless $no_title_change is set
case ${no_title_change-$TERM} in
xterm*|rxvt*)
    PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1"
    ;;
*)
    ;;
esac

...

If you unconditionally want to remove the title-changing logic, just replace this snippet with nothing.

The use case of opening a separate terminal window for each in a set of tasks is dubious; a better practice generally is to run your tasks as background processes, each with output to a file. Then you can automate monitoring and logging for the entire scenario, and avoid silly problems like terminating a process by mistake by accidentally closing the wrong terminal window; and managing the processes remotely from multiple locations becomes feasible.
