Can’t remove /usr/local/bin path in PATH

BudiKusasi · 10-19-2021, 05:26 PM

How to remove /usr/local/bin path in PATH as :

Code:

$ cat /etc/profile 
# /etc/profile

# Set our umask
umask 022

# Append "$1" to $PATH when not already in.
# This function API is accessible to scripts in /etc/profile.d
append_path () {
    case ":$PATH:" in
        *:"$1":*)
            ;;
        *)
            PATH="${PATH:+$PATH:}$1"
    esac
}

# Append our default paths
#append_path '/usr/local/sbin'
#append_path '/usr/local/bin'
append_path '/usr/bin'

# Force PATH to be environment
export PATH

# Load profiles from /etc/profile.d
if test -d /etc/profile.d/; then
	for profile in /etc/profile.d/*.sh; do
		test -r "$profile" && . "$profile"
	done
	unset profile
fi

# Unload our profile API functions
unset -f append_path

# Source global bash config, when interactive but not posix or sh mode
if test "$BASH" &&\
   test "$PS1" &&\
   test -z "$POSIXLY_CORRECT" &&\
   test "${0#-}" != sh &&\
   test -r /etc/bash.bashrc
then
	. /etc/bash.bashrc
fi

# Termcap is outdated, old, and crusty, kill it.
unset TERMCAP

# Man is much better than us at figuring this out
unset MANPATH

$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/bin/site_perl:/usr/bin/vendor_perl

Can’t work
Please help out, thanks before

Code:

$ echo $PATH
/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin
$ echo ${PATH///usr\/local\/bin:}
/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin

Please note that this substitution construct is Bash-specific, while Debian-based systems use DASH as their /bin/sh. So this won't work in a /bin/sh script there.

C-Shell and Zsh use an array $path automatically synchronized with $PATH. For DASH, we can build something similar:

Code:

set -- $(IFS=:;echo $PATH|sed 's|/usr/local/bin||')
PATH=$(IFS=:;echo "$*")

Update. Ah sorry, I misunderstood the question. So your problem is that $PATH still includes /usr/local/bin even after commenting it out in /etc/profile, right? Well, it could be also set somewhere else. Check all shell startup files on your system as well as other relevant system locations. E.g. on some systems, PATH may be set in /etc/login.defs, /etc/environment, or /etc/security/pam_env.conf. And don't forget that according to the login(1) manual page

Quote:

$PATH defaults to /usr/local/bin:/bin:/usr/bin for normal users, and to /usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin for root, if not otherwise configured.

Or, rather than chasing after it in system files, just redefine it in your ~/.bashrc. It's much easier to remove it locally for the user who doesn't need it than disabling it globally for all users in some obscure system location and then trying to remember where that place were when you'll need it again later.

Did you log out then back in?

I personally like to global my path in the /etc/environment file as I'm the only console user around here. Maybe MX does that by default? That would override I'd think. I've never used MX so I can't be sure of course.

When you tell us why we will teach you the variable export
