[英]Access a file on remote/cluster directly
I am trying to compare two files one local and other one on remote.我正在尝试比较两个文件,一个是本地文件,另一个是远程文件。 I used
我用了
meld a.txt user@host:/home/user/john/b.txt
This was not possible because file could not be detected.这是不可能的,因为无法检测到文件。 However, I could copy the same file from the same location to local via
scp
and do the comparison afterwards.但是,我可以通过
scp
将同一个文件从同一个位置复制到本地,然后进行比较。 How to access the file directly on cluster for example like:如何直接在集群上访问文件,例如:
vim user@host:/home/user/john/b.txt
In bash, you can create a file from a process with <(...)
:在 bash 中,您可以使用
<(...)
从进程创建文件:
meld a.txt <(ssh user@host cat /path/to/file/b.txt)
If you want to modify the remote file, you'll have to use some mounting.如果要修改远程文件,则必须使用一些挂载。
One way to do it is to use sshfs一种方法是使用sshfs
# sshfs setup
mkdir ~/remote
sshfs user@host:/path/to/file ~/remote
# meld invocation
meld a.txt ~/remote/b.txt
Try save the remote file to your linux system and simply use diff -y file1 file2
command.尝试将远程文件保存到您的 linux 系统并简单地使用
diff -y file1 file2
命令。 You will see the diff between.你会看到两者之间的差异。
Check the path in your example, I think it's incorrect.检查您示例中的路径,我认为它不正确。 Try directly:
直接试试:
vim john@server:b.text
That should work.那应该行得通。
