+.. class:: infomark
+
+**Purpose**
+
+The **diff** utility is a data comparison tool that calculates and displays the differences between two files.
+
+Unlike edit distance notions used for other purposes, diff is line-oriented rather than character-oriented, but it is like Levenshtein distance in that it tries to determine the smallest set of deletions and insertions to create one file from the other.
+
+The diff command displays the changes made in a standard format, such that both humans and machines can understand the changes and apply them: given one file and the changes, the other file can be created.
+
+.. class:: infomark
+
+**Input**
+
+Two text files to be checked for differences line by line.
+
+.. class:: infomark
+
+**Output**
+
+A *single text file*, either:
+
+- containing the lines differences in **unified format** (*unidiff*),
+
+- or an **empty** file if the two input files are the same.
