42.Op Fl f Ar min.max
43.Op Fl s Ar sepstring
44.Op Fl t Ar c

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