Top Forums Shell Programming and Scripting How to insert a word into a text file? Post 302874579 by Yoda on Friday 15th of November 2013 03:30:16 PM

I guess using '1' makes the program more cryptic rather than making it simple. To conserve space, programmers normally use '1' instead of print.

In awk the default action if a condition is true is to print record.

So you can use any number other than 0 to print record, this is because 0 represents false and non-zero represents true.
Code:
awk 1 filename # will print records in file
awk 5 filename # will print records in file
awk 0 filename # will not print records in file

Text::FormatTable(3pm)					User Contributed Perl Documentation				    Text::FormatTable(3pm)

NAME
Text::FormatTable - Format text tables SYNOPSIS
my $table = Text::FormatTable->new('r|l'); $table->head('a', 'b'); $table->rule('='); $table->row('c', 'd'); print $table->render(20); DESCRIPTION
Text::FormatTable renders simple tables as text. You pass to the constructor (new) a table format specification similar to LaTeX (e.g. "r|l|5l|R|20L") and you call methods to fill the table data and insert rules. After the data is filled, you call the render method and the table gets formatted as text. Methods: new($format) Create a Text::FormatTable object, the format of each column is specified as a character of the $format string. The following formats are defined: l Left-justified top aligned word-wrapped text. L Left-justified bottom aligned word-wrapped text. r Right-justified top aligned word-wrapped text. R Right-justified bottom aligned word-wrapped text. 10R, 20r, 15L, 12l, Number is fixed width of the column. Justified and aligned word-wrapped text (see above). ' ' A space. | Column separator. head($col1, $col2, ...) Add a header row using $col1, $col2, etc. as cell contents. Note that, at the moment, header rows are treated like normal rows. row($col1, $col2, ...) Add a row with $col1, $col2, etc. as cell contents. rule([$char]) Add an horizontal rule. If $char is specified it will be used as character to draw the rule, otherwise '-' will be used. render([$screen_width]) Return the rendered table formatted with $screen_width or 79 if it is not specified.
