45.Sh DESCRIPTION
46The
47.Nm
48utility copies the named files side by side onto the standard output.
49The
50.Em n-th
51input lines from the input
52.Ar files
53are considered fragments of the single long
54.Em n-th
55output line into which they are assembled.
56The name `\fB\-\fP' means the standard input, and may be repeated.
57.Pp
58.Bl -tag -width indent
59.It Fl f Ar min . Ns Ar max , Fl F Ar min . Ns Ar max
60Print line fragments according to the format string
61.Ar min . Ns Ar max ,
62where
63.Ar min
64is the minimum field width and
65.Ar max
66the maximum field width.
67If
68.Ar min
69begins with a zero, zeros will be added to make up the field width,
70and if it begins with a `\-', the fragment will be left-adjusted
71within the field.
72Using
73.Fl f
74applies only to the next file while
75.Fl F
76applies to all subsequent files until it appears again uncapitalized.
77.It Fl p Ar min . Ns Ar max , Fl P Ar min . Ns Ar max
78Like
79.Fl f ,
80but pad this file's field when end-of-file is reached
81and other files are still active.
82Using
83.Fl p
84applies only to the next file while
85.Fl P
86applies to all subsequent files until it appears again uncapitalized.
87.It Fl s Ar sepstring , Fl S Ar sepstring
88Print
89.Ar sepstring
90before printing line fragments from the next file.
91This option may appear after the last file.
92Using
93.Fl s
94applies only to the next file while
95.Fl S
96applies to all subsequent files until it appears again uncapitalized.
97.It Fl t Ar c , Fl T Ar c
98The input line terminator is
99.Ar c
100instead of a newline.
101The newline normally appended to each output line is omitted.
102Using
103.Fl t
104applies only to the next file while
105.Fl T
106applies to all subsequent files until it appears again uncapitalized.
107.El
108.Pp
109To print files simultaneously for easy viewing use
110.Xr pr 1 .
111.Sh EXAMPLES
112The command
113.Bd -literal
114lam file1 file2 file3 file4
115.Ed
116.Pp
117joins 4 files together along each line.
118To merge the lines from four different files use
119.Bd -literal
120lam file1 \-S "\\
121" file2 file3 file4
122.Ed
123.Pp
124Every 2 lines of a file may be joined on one line with
125.Bd -literal
126lam \- \- < file
127.Ed
128.Pp
129and a form letter with substitutions keyed by `@' can be done with
130.Bd -literal
131lam \-t @ letter changes

138.Sh STANDARDS
139Some of the functionality of
140.Nm
141is standardized as the
142.Xr paste 1
143utility by
144.St -p1003.2 .
