47.Sh DESCRIPTION
48The
49.Nm
50utility copies the named files side by side onto the standard output.
51The
52.Em n-th
53input lines from the input
54.Ar files
55are considered fragments of the single long
56.Em n-th
57output line into which they are assembled.
58The name `\fB\-\fP' means the standard input, and may be repeated.
59.Pp
60.Bl -tag -width indent
61.It Fl f Ar min . Ns Ar max , Fl F Ar min . Ns Ar max
62Print line fragments according to the format string
63.Ar min . Ns Ar max ,
64where
65.Ar min
66is the minimum field width and
67.Ar max
68the maximum field width.
69If
70.Ar min
71begins with a zero, zeros will be added to make up the field width,
72and if it begins with a `\-', the fragment will be left-adjusted
73within the field.
74Using
75.Fl f
76applies only to the next file while
77.Fl F
78applies to all subsequent files until it appears again uncapitalized.
79.It Fl p Ar min . Ns Ar max , Fl P Ar min . Ns Ar max
80Like
81.Fl f ,
82but pad this file's field when end-of-file is reached
83and other files are still active.
84Using
85.Fl p
86applies only to the next file while
87.Fl P
88applies to all subsequent files until it appears again uncapitalized.
89.It Fl s Ar sepstring , Fl S Ar sepstring
90Print
91.Ar sepstring
92before printing line fragments from the next file.
93This option may appear after the last file.
94Using
95.Fl s
96applies only to the next file while
97.Fl S
98applies to all subsequent files until it appears again uncapitalized.
99.It Fl t Ar c , Fl T Ar c
100The input line terminator is
101.Ar c
102instead of a newline.
103The newline normally appended to each output line is omitted.
104Using
105.Fl t
106applies only to the next file while
107.Fl T
108applies to all subsequent files until it appears again uncapitalized.
109.El
110.Pp
111To print files simultaneously for easy viewing use
112.Xr pr 1 .
113.Sh EXAMPLES
114The command
115.Bd -literal
116lam file1 file2 file3 file4
117.Ed
118.Pp
119joins 4 files together along each line.
120To merge the lines from four different files use
121.Bd -literal
122lam file1 \-S "\\
123" file2 file3 file4
124.Ed
125.Pp
126Every 2 lines of a file may be joined on one line with
127.Bd -literal
128lam \- \- < file
129.Ed
130.Pp
131and a form letter with substitutions keyed by `@' can be done with
132.Bd -literal
133lam \-t @ letter changes

140.Sh STANDARDS
141Some of the functionality of
142.Nm
143is standardized as the
144.Xr paste 1
145utility by
146.St -p1003.2 .
