I first install docker through following command from docker site:
我首先通过docker site的以下命令安装docker:
curl -s -O https://get.docker.com/builds/Linux/x86_64/docker-1.6.1 && chmod +x docker-1.6.1 && sudo mv docker-1.6.1 /usr/local/bin/docker
Then I remove the docker
in /usr/local/bin
directory.
然后我删除/ usr / local / bin目录中的docker。
I install docker
through yum
again, this time docker
is installed in /usr/bin
directory:
我再次通过yum安装docker,这次docker安装在/ usr / bin目录中:
[root@dl380gen8snbjbb ~]# ls -lt /usr/bin/docker
-rwxr-xr-x 1 root root 13451927 Apr 20 13:44 /usr/bin/docker
When I execute docker
in command:
当我在命令中执行docker时:
[root@dl380gen8snbjbb ~]# docker
-bash: /usr/local/bin/docker: No such file or directory
but the /usr/bin
is actually in PATH
:
但是/ usr / bin实际上是在PATH中:
[root@dl380gen8snbjbb ~]# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin
Why does the system doesn't seek docker
command in /usr/bin
directory?
为什么系统不在/ usr / bin目录中寻找docker命令?

bash does cache the full path to a command. You can verify that the command you are trying to execute is hashed with the type command:
bash会缓存命令的完整路径。您可以使用type命令验证您尝试执行的命令是否已经过哈希处理:
$ type svnsync svnsync is hashed (/usr/local/bin/svnsync)
$ type svnsync svnsync被哈希(/ usr / local / bin / svnsync)
To clear the entire cache:
要清除整个缓存:
$ hash -r
$ hash -r
Or just one entry:
或者只是一个条目:
$ hash -d svnsync
$ hash -d svnsync
For additional information, consult help hash and man bash.
