+.PC "Return the length of its argument or input file"
+\fBlength [\fIstring\fB] [< \fIfile\fB]\fR
+.PP
+.II "length of string"
+.II "string^length"
+The command
+.B length
+outputs the number of characters in its first argument.
+If there
+is no argument, it reads the standard input.
+.PP
+Because
+.B length
+counts only its first argument, you must put quotation marks
+around all of the words on the command line to make them one argument.
+.PP
+.II wc
+.B length
+uses
+.B "wc -c"
+to do the counting.
+.SH Example
+Here we find the length of a string and a file.
+.DM
+	length aA1
+.DE
+.PP
+This returns \fB3\fR.
+.PP
+The next command
+.DM
+	length 'word1 word2'
+.DE
+.PP
+returns \fB11\fR \(em that is, the length of
+.B word1
+plus
+.B word2
+plus the space between them.
+.PP
+The final example measures the number of characters in file
+.BR length.1 :
+.DM
+	length < length.1
+.DE
+.PP
+Note that you need must quote strings if they have spaces or tabs in them.
