c -- Command Print multi-column output c [ -lN ] [ -wN ] [ -012 ] c reads lines from the standard input and writes them in columns on the standard output. The longest input line and the width of the page determine how many columns will fit across the page. c recognizes the following options: -lN Set the length of the page to N lines. c columnizes its output by pages when this option is used with mode 1 or mode 2. -wN Set the width of the page to N characters. The default is 80. -0 Multi-column mode 0. Order the fields horizontally across the page. -1 Multi-column mode 1 (default mode). Order the fields vertically down each column; the last column may be short. -2 Multi-column mode 2. Order the fields similarly to mode 1, but place blank fields in the last output line rather than the last column. Options may also be given in the environmental variable C, separated by white space. Command line options override options in the environment. For example, export C="-l56 -w72 -2" c -w80 <file1 has the same effect as c -l56 -w72 -2 -w80 <file1 This command sets the page width to 80 rather than to 72. See Also commands, export, pr Diagnostics c prints ``out of memory'' and returns an exit status of one if it cannot allocate enough memory to process its input.
