1.1 deraadt 47: .Sh DESCRIPTION
48: The
49: .Nm paste
50: utility concatenates the corresponding lines of the given input files,
51: replacing all but the last file's newline characters with a single tab
52: character, and writes the resulting lines to standard output.
53: If end-of-file is reached on an input file while other input files
54: still contain data, the file is treated as if it were an endless source
55: of empty lines.
56: .Pp
57: The options are as follows:
1.6 aaron 58: .Bl -tag -width Ds
1.5 aaron 59: .It Fl d Ar list
1.1 deraadt 60: Use one or more of the provided characters to replace the newline
61: characters instead of the default tab.
62: The characters in
63: .Ar list
64: are used circularly, i.e., when
65: .Ar list
66: is exhausted the first character from
67: .Ar list
68: is reused.
69: This continues until a line from the last input file (in default operation)
1.3 aaron 70: or the last line in each file (using the
71: .Fl s
72: option) is displayed, at which
1.1 deraadt 73: time
74: .Nm paste
75: begins selecting characters from the beginning of
76: .Ar list
77: again.
78: .Pp
79: The following special characters can also be used in list:
80: .Pp
81: .Bl -tag -width flag -compact
82: .It Li \en
83: newline character
84: .It Li \et
85: tab character
86: .It Li \e\e
87: backslash character
88: .It Li \e0
1.3 aaron 89: empty string (not a null character)
1.1 deraadt 90: .El
91: .Pp
92: Any other character preceded by a backslash is equivalent to the
93: character itself.
94: .It Fl s
95: Concatenate all of the lines of each separate input file in command line
96: order.
97: The newline character of every line except the last line in each input
98: file is replaced with the tab character, unless otherwise specified by
1.3 aaron 99: the
100: .Fl d
101: option.
1.1 deraadt 102: .El
103: .Pp
104: If
1.5 aaron 105: .Dq -
1.1 deraadt 106: is specified for one or more of the input files, the standard
107: input is used; standard input is read one line at a time, circularly,
108: for each instance of
1.5 aaron 109: .Dq - .
1.1 deraadt 110: .Pp
111: The
112: .Nm paste
1.3 aaron 113: utility exits 0 on success or >0 if an error occurred.
1.8 jmc 114: .Sh EXAMPLES
115: List the files in the current directory in three columns:
116: .Pp
117: .Dl "$ ls | paste - - -"
118: .Pp
119: Combine pairs of lines from
120: .Ar file
121: into single lines:
122: .Pp
123: .Dl "$ paste -s -d '\et\en' file"
124: .Pp
125: Number the lines in
126: .Ar file ,
127: similar to
128: .Ql cat -n :
129: .Pp
130: .Dl "$ sed = file | paste -s -d '\et\en' - -"
131: .Pp
132: Create a colon-separated list of directories named
133: .Pa bin ,
134: suitable
135: for use in the
136: .Ev PATH
137: environment variable:
138: .Pp
139: .Dl "$ find / -name bin -type d | paste -s -d : -"
