48.Sh DESCRIPTION
49The
50.Nm
51utility copies the named files side by side onto the standard output.
52The
53.Em n-th
54input lines from the input
55.Ar files
56are considered fragments of the single long
57.Em n-th
58output line into which they are assembled.
59The name `\fB\-\fP' means the standard input, and may be repeated.
60.Pp
61.Bl -tag -width indent
62.It Fl f Ar min . Ns Ar max , Fl F Ar min . Ns Ar max
63Print line fragments according to the format string
64.Ar min . Ns Ar max ,
65where
66.Ar min
67is the minimum field width and
68.Ar max
69the maximum field width.
70If
71.Ar min
72begins with a zero, zeros will be added to make up the field width,
73and if it begins with a `\-', the fragment will be left-adjusted
74within the field.
75Using
76.Fl f
77applies only to the next file while
78.Fl F
79applies to all subsequent files until it appears again uncapitalized.
80.It Fl p Ar min . Ns Ar max , Fl P Ar min . Ns Ar max
81Like
82.Fl f ,
83but pad this file's field when end-of-file is reached
84and other files are still active.
85Using
86.Fl p
87applies only to the next file while
88.Fl P
89applies to all subsequent files until it appears again uncapitalized.
90.It Fl s Ar sepstring , Fl S Ar sepstring
91Print
92.Ar sepstring
93before printing line fragments from the next file.
94This option may appear after the last file.
95Using
96.Fl s
97applies only to the next file while
98.Fl S
99applies to all subsequent files until it appears again uncapitalized.
100.It Fl t Ar c , Fl T Ar c
101The input line terminator is
102.Ar c
103instead of a newline.
104The newline normally appended to each output line is omitted.
105Using
106.Fl t
107applies only to the next file while
108.Fl T
109applies to all subsequent files until it appears again uncapitalized.
110.El
111.Pp
112To print files simultaneously for easy viewing use
113.Xr pr 1 .
114.Sh EXAMPLES
115The command
116.Bd -literal
117lam file1 file2 file3 file4
118.Ed
119.Pp
120joins 4 files together along each line.
121To merge the lines from four different files use
122.Bd -literal
123lam file1 \-S "\\
124" file2 file3 file4
125.Ed
126.Pp
127Every 2 lines of a file may be joined on one line with
128.Bd -literal
129lam \- \- < file
130.Ed
131.Pp
132and a form letter with substitutions keyed by `@' can be done with
133.Bd -literal
134lam \-t @ letter changes
135.Ed

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

149The
150.Nm
151utility first appeared in
