meld:tldr:08a1e
The command "meld" is a file and directory comparison tool in Linux. It allows users to compare and merge two different files or directories.
In the given command, the syntax is: "meld ${filename_1} ${filename_2}". Here, "${filename_1}" and "${filename_2}" are placeholder variables representing the names of two files that you want to compare and merge using the meld tool.
To use this command, you need to replace "${filename_1}" and "${filename_2}" with the actual names of the files you want to compare. For example, if you have two files named "file1.txt" and "file2.txt" in the current directory, you can use the command as follows:
meld file1.txt file2.txt
This will open the meld tool and display a graphical comparison of the two files, showing the differences between them and allowing you to merge the changes if desired.
