Easy methods to Evaluate Native and Distant Information in Linux

April 15, 2019

On this article, we are going to present the right way to evaluate or discover the distinction between native and distant information in Linux. In a current put up, we reviewed 9 greatest file comparability and distinction (Diff) instruments for Linux. One of many instruments we lined was diff.

diff (quick for distinction) is a straightforward and straightforward to make use of software which analyzes two information and shows the variations within the information by evaluating the information line by line. It prints the strains which can be completely different. Importantly, if you’d like the 2 information to be an identical to one another, diff additionally outputs a set of helpful directions on the right way to change one file to make it an identical to the second file.

To match or discover the distinction between two information on completely different servers, run the next command. Bear in mind to interchange the consumer and distant host along with your precise parameters.

$ ssh [email protected] “cat /house/root/file_remote” | diff – file_local

Evaluate Two Information on Totally different Servers

Be aware which you can additionally save the distinction between the 2 information to a file, utilizing the output redirection characteristic. For instance:

$ ssh [email protected] “cat /house/root/file_remote” | diff – file_local > diff_output.txt

Then use a cat command to view the contents of the diff_output.txt file.

$ cat diff_output.txt
OR
$ bcat diff_output.txt

As well as, you can too evaluate or discover the distinction between two information on two distant servers, as proven:

$ diff <(ssh [email protected] 'cat /path/to/file1') <(ssh [email protected] 'cat /path/to/file2')

For extra data, seek the advice of the diff man web page as proven.

$ man diff
