我刚刚在〜/ local / bin /中在本地安装了sed的检测版本-但是，我很惊讶地看到以下内容：
sed --version sed (GNU sed) 4.7 Packaged by Debian `which sed` --version /home/xxx/local/bin/sed (GNU sed) 4.8 Copyright (C) 2020 Free Software Foundation, Inc.
What is causing
which to return a path which is not the path actually used by bash when issuing the command ? Or am I making a giant mistake somewhere ?
