diff: Compare files, showing the differences side by side.
$ diff --side-by-side ${old_file} ${new_file}
try on your machine
This command diff --side-by-side ${old_file} ${new_file}
is used to compare two files side by side and display the differences between them.
Here's a breakdown of the command:
diff
: is the command itself, used to compare two files and highlight the differences between them.--side-by-side
: is an option or flag that specifies the output format will be displayed side by side. This means that the differences between the files will be shown in parallel columns, making it easier to compare them.${old_file}
: is a placeholder for the path or name of the old (or original) file you want to compare. You need to replace${old_file}
with the actual value, for example,file1.txt
.${new_file}
: another placeholder for the path or name of the new (or modified) file you want to compare. Similarly, you need to replace${new_file}
with the actual value, for example,file2.txt
.
To use this command, you would typically open a terminal or command prompt, navigate to the directory where the files are located, and execute the command with the actual file names provided. The output will then be displayed, showing the differences between the two files side by side.
