": command not found" in terminal startup

[rockhazard]

Hey, folks. I have a perplexing problem. When I startup my terminal emulator (GNOME Terminal 3.0.1) or a virtual terminal, it immediately prints ": command not found" above my prompt. I'm thinking it's something in my .bashrc file, although I've used this same unchanged file successfully without a hitch for nearly two years across various versions of Ubuntu and Mint. Any idea what gives? Here is my .bashrc:

Code: Select all

# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples
# user-change begun on 07-20-10

# If not running interactively, don't do anything
[ -z "$PS1" ] && return

# don't put duplicate lines in the history. See bash(1) for more options
# don't overwrite GNU Midnight Commander's setting of `ignorespace'.
HISTCONTROL=$HISTCONTROL${HISTCONTROL+,}ignoredups
# ... or force ignoredups and ignorespace
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)

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

# make less more friendly for non-text input files, see lesspipe(1)
[ -x /usr/bin/lesspipe ] && eval "$(SHELL=/bin/sh lesspipe)"

# set variable identifying the chroot you work in (used in the prompt below)
if [ -z "$debian_chroot" ] && [ -r /etc/debian_chroot ]; then
    debian_chroot=$(cat /etc/debian_chroot)
fi

# set a fancy prompt (non-color, unless we know we "want" color)
case "$TERM" in
    xterm-color) color_prompt=yes;;
esac

# uncomment for a colored prompt, if the terminal has the capability; turned
# off by default to not distract the user: the focus in a terminal window
# should be on the output of commands, not on the prompt
force_color_prompt=yes

if [ -n "$force_color_prompt" ]; then
    if [ -x /usr/bin/tput ] && tput setaf 1 >&/dev/null; then
	# We have color support; assume it's compliant with Ecma-48
	# (ISO/IEC-6429). (Lack of such support is extremely rare, and such
	# a case would tend to support setf rather than setaf.)
	color_prompt=yes
    else
	color_prompt=
    fi
fi

I thought about debugging the file as it runs (like you can for a shell script), but I don't know how for .bashrc. Thanks for any assistance...

Try these

Code: Select all

bash -x ~/.bashrc

[riffraff]

Maybe your PS1-Setting?

Does /etc/debian_chroot exists? (Because this is in your PS1 right after the ":"...)

[Habitual]

restore the original line.

Code: Select all

    #PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ ' # original
    PS1="$HC[${debian_chroot:+($debian_chroot)}$FWHT\u$FCYN@$FWHT\h:$FCYN\@:$FCYN\w$RS$HC]\\$ $RS" # user-change

THEN, You can test your intended changes by just entering

Code: Select all

PS1="$HC[${debian_chroot:+($debian_chroot)}$FWHT\u$FCYN@$FWHT\h:$FCYN\@:$FCYN\w$RS$HC]\\$ $RS"

in a/the terminal window.

a clock in the prompt?
I get this using your PS1 variable:

Code: Select all

[jj@MyKung-Fu:04:19 PM:~]$

in terminal first, once it works without issue, THEN replace the PS1 line in .bashrc as you have previously.

I have C:\jj > as my prompt, I used to have a clock in there also, but I had unexpected results. It was a painful couple of hours getting it to (mostly) work.

Edit:

I see

Code: Select all

PS2="> $RS"

but no further definition of $RS - where did that come from?
