print
StatementUse the print
statement to produce output with simple, standardized
formatting. You specify only the strings or numbers to print, in a
list separated by commas. They are output, separated by single spaces,
followed by a newline. The statement looks like this:
print item1, item2, …
The entire list of items may be optionally enclosed in parentheses. The parentheses are necessary if any of the item expressions uses the ‘>’ relational operator; otherwise it could be confused with an output redirection (see Redirection).
The items to print can be constant strings or numbers, fields of the
current record (such as $1
), variables, or any awk
expression. Numeric values are converted to strings and then printed.
The simple statement ‘print’ with no items is equivalent to
‘print $0’: it prints the entire current record. To print a blank
line, use ‘print ""’.
To print a fixed piece of text, use a string constant, such as
"Don't Panic"
, as one item. If you forget to use the
double-quote characters, your text is taken as an awk
expression, and you will probably get an error. Keep in mind that a
space is printed between any two items.
Note that the print
statement is a statement and not an
expression—you can’t use it in the pattern part of a
pattern–action statement, for example.
