Removing PATH on LINUX

path_delete

Create a script called remove_path_part with the contents

echo ":$PATH:" | sed "s@:$1:@:@g;s@^:\(.*\):\$@\1@"

and a script called prepend_path_part with the contents

if echo ":$PATH:" | grep -q ":$1:"; then echo "$PATH"; else echo "$1:$PATH"; fi

and a script called append_path_part with the contents

if echo ":$PATH:" | grep -q ":$1:"; then echo "$PATH"; else echo "$PATH:$1"; fi

make them all executable, and then call them like:

    PATH=$(remove_path_part /path/to/remove)
    PATH=$(prepend_path_part /path/to/remove)
    PATH=$(append_path_part /path/to/remove)
