+=== File
73 
+
74 
+Prints a file's contents at the specified line, and/or its modification time.
75 
+
76 
++format+ specifies how the file should be displayed. It has the following variables:
77 
+
78 
++%contents+ displays the file's contents according to +line+, +skip+, and +limit+.
79 
+
80 
++%mtime+ shows the file's modification time according to +mtime_format+. By default,
81 
+"%H:%M:%S" is used.
82 
+
83 
++%mtime_diff+ expands to the file's age in a coarse, concise, human-readable format.
84 
+For example, "1y" or "28m". Only the largest unit of time is displayed.
85 
+
86 
++mtime_format+ defines which units of time should be displayed as specified by
87 
+strftime(3).
88 
+
89 
++line+ specifies which line (delimited by "\r", "\n", or "\r\n") should be displayed.
90 
+Negative values for +line+ will be counted from the bottom. For example, +line = -1+
91 
+behaves similarly to tail(1). If the line does not exist, +%contents+ will be blank.
92 
+Note that many plain text files contain a trailing newline, in which case you should
93 
+subtract one from the desired +line+ when using a negative value.
94 
+
95 
+i3status removes +skip+ bytes from the beginning of the specified line before
96 
+displaying it. Similarly, i3status will not display more than +limit+ bytes
97 
+after +skip+.

 After installing dzen2, you can directly use it with i3status. Just ensure that
