awk - pattern-directed scanning and processing language
𝐒𝐘𝐍𝐎𝐏𝐒𝐈𝐒
𝗮𝘄𝗸 [ -𝐅 f̲s̲ ] [ -𝘃 v̲a̲r̲=̲v̲a̲l̲u̲e̲ ] [ '̲p̲r̲o̲g̲'̲ | -𝗳 p̲r̲o̲g̲f̲i̲l̲e̲ ] [ f̲i̲l̲e̲ .̲.̲.̲ ]
𝐃𝐄𝐒𝐂𝐑𝐈𝐏𝐓𝐈𝐎𝐍
A̲w̲k̲ scans each input f̲i̲l̲e̲ for lines that match any of a set of patterns
specified literally in p̲r̲o̲g̲ or in one or more files specified as -𝗳 p̲r̲o̲g̲‐̲
f̲i̲l̲e̲. With each pattern there can be an associated action that will be
performed when a line of a f̲i̲l̲e̲ matches the pattern. Each line is
matched against the pattern portion of every pattern-action statement;
the associated action is performed for each matched pattern. The file
name - means the standard input. Any f̲i̲l̲e̲ of the form v̲a̲r̲=̲v̲a̲l̲u̲e̲ is
treated as an assignment, not a filename, and is executed at the time it
would have been opened if it were a filename. The option -𝘃 followed by
v̲a̲r̲=̲v̲a̲l̲u̲e̲ is an assignment to be done before p̲r̲o̲g̲ is executed; any number
of -𝘃 options may be present. The -𝐅 f̲s̲ option defines the input field
separator to be the regular expression f̲s̲.
An input line is normally made up of fields separated by white space, or
by the regular expression 𝐅𝐒. The fields are denoted $𝟭, $𝟮, ..., while
$𝟬 refers to the entire line. If 𝐅𝐒 is null, the input line is split
into one field per character.
A pattern-action statement has the form:
p̲a̲t̲t̲e̲r̲n̲ { a̲c̲t̲i̲o̲n̲ }
A missing { a̲c̲t̲i̲o̲n̲ } means print the line; a missing pattern always
matches. Pattern-action statements are separated by newlines or semi‐
colons.
An action is a sequence of statements. A statement can be one of the
following:
if( e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲ ) s̲t̲a̲t̲e̲m̲e̲n̲t̲ [ else s̲t̲a̲t̲e̲m̲e̲n̲t̲ ]
while( e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲ ) s̲t̲a̲t̲e̲m̲e̲n̲t̲
for( e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲ ; e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲ ; e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲ ) s̲t̲a̲t̲e̲m̲e̲n̲t̲
for( v̲a̲r̲ in a̲r̲r̲a̲y̲ ) s̲t̲a̲t̲e̲m̲e̲n̲t̲
do s̲t̲a̲t̲e̲m̲e̲n̲t̲ while( e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲ )
break
continue
{ [ s̲t̲a̲t̲e̲m̲e̲n̲t̲ .̲.̲.̲ ] }
e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲ # commonly v̲a̲r̲ =̲ e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲
print [ e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲-̲l̲i̲s̲t̲ ] [ > e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲ ]
printf f̲o̲r̲m̲a̲t̲ [ , e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲-̲l̲i̲s̲t̲ ] [ > e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲ ]
return [ e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲ ]
next # skip remaining patterns on this input line
nextfile # skip rest of this file, open next, start at top
delete a̲r̲r̲a̲y̲[ e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲ ]# delete an array element
delete a̲r̲r̲a̲y̲ # delete all elements of array
exit [ e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲ ] # exit immediately; status is e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲
Statements are terminated by semicolons, newlines or right braces. An
empty e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲-̲l̲i̲s̲t̲ stands for $𝟬. String constants are quoted " ",
with the usual C escapes recognized within. Expressions take on string
or numeric values as appropriate, and are built using the operators + - *
/ % ^ (exponentiation), and concatenation (indicated by white space).
The operators ! ++ -- += -= *= /= %= ^= > >= < <= == != ?: are also
available in expressions. Variables may be scalars, array elements (de‐
noted x̲[i̲]) or fields. Variables are initialized to the null string.
Array subscripts may be any string, not necessarily numeric; this allows
for a form of associative memory. Multiple subscripts such as [𝗶,𝗷,𝗸]
are permitted; the constituents are concatenated, separated by the value
of 𝐒𝐔𝐁𝐒𝐄𝐏.
The 𝗽𝗿𝗶𝗻𝘁 statement prints its arguments on the standard output (or on a
file if > f̲i̲l̲e̲ or >> f̲i̲l̲e̲ is present or on a pipe if | c̲m̲d̲ is present),
separated by the current output field separator, and terminated by the
output record separator. f̲i̲l̲e̲ and c̲m̲d̲ may be literal names or parenthe‐
sized expressions; identical string values in different statements denote
the same open file. The 𝗽𝗿𝗶𝗻𝘁𝗳 statement formats its expression list ac‐
cording to the f̲o̲r̲m̲a̲t̲ (see p̲r̲i̲n̲t̲f̲(3)). The built-in function 𝗰𝗹𝗼𝘀𝗲(e̲x̲p̲r̲)
closes the file or pipe e̲x̲p̲r̲. The built-in function 𝗳𝗳𝗹𝘂𝘀𝗵(e̲x̲p̲r̲) flushes
any buffered output for the file or pipe e̲x̲p̲r̲.
The mathematical functions 𝗮𝘁𝗮𝗻𝟮, 𝗰𝗼𝘀, 𝗲𝘅𝗽, 𝗹𝗼𝗴, 𝘀𝗶𝗻, and 𝘀𝗾𝗿𝘁 are built
in. Other built-in functions:
𝗹𝗲𝗻𝗴𝘁𝗵 the length of its argument taken as a string, number of elements
in an array for an array argument, or length of $𝟬 if no argu‐
ment.
𝗿𝗮𝗻𝗱 random number on [0,1).
𝘀𝗿𝗮𝗻𝗱 sets seed for 𝗿𝗮𝗻𝗱 and returns the previous seed.
𝗶𝗻𝘁 truncates to an integer value.
𝘀𝘂𝗯𝘀𝘁𝗿(s̲, m̲ [, n̲])
the n̲-character substring of s̲ that begins at position m̲ counted
from 1. If no n̲, use the rest of the string.
𝗶𝗻𝗱𝗲𝘅(s̲, t̲)
the position in s̲ where the string t̲ occurs, or 0 if it does not.
𝗺𝗮𝘁𝗰𝗵(s̲, r̲)
the position in s̲ where the regular expression r̲ occurs, or 0 if
it does not. The variables 𝐑𝐒𝐓𝐀𝐑𝐓 and 𝐑𝐋𝐄𝐍𝐆𝐓𝐇 are set to the po‐
sition and length of the matched string.
𝘀𝗽𝗹𝗶𝘁(s̲, a̲ [, f̲s̲])
splits the string s̲ into array elements a̲[𝟭], a̲[𝟮], ..., a̲[n̲],
and returns n̲. The separation is done with the regular expres‐
sion f̲s̲ or with the field separator 𝐅𝐒 if f̲s̲ is not given. An
empty string as field separator splits the string into one array
element per character.
𝘀𝘂𝗯(r̲, t̲ [, s̲])
substitutes t̲ for the first occurrence of the regular expression
r̲ in the string s̲. If s̲ is not given, $𝟬 is used.
𝗴𝘀𝘂𝗯(r̲, t̲ [, s̲])
same as 𝘀𝘂𝗯 except that all occurrences of the regular expression
are replaced; 𝘀𝘂𝗯 and 𝗴𝘀𝘂𝗯 return the number of replacements.
𝘀𝗽𝗿𝗶𝗻𝘁𝗳(f̲m̲t̲, e̲x̲p̲r̲, .̲.̲.̲)
the string resulting from formatting e̲x̲p̲r̲ .̲.̲.̲ according to the
p̲r̲i̲n̲t̲f̲(3) format f̲m̲t̲.
𝘀𝘆𝘀𝘁𝗲𝗺(c̲m̲d̲)
executes c̲m̲d̲ and returns its exit status. This will be -1 upon
error, c̲m̲d̲'s exit status upon a normal exit, 256 + s̲i̲g̲ upon
death-by-signal, where s̲i̲g̲ is the number of the murdering signal,
or 512 + s̲i̲g̲ if there was a core dump.
𝘁𝗼𝗹𝗼𝘄𝗲𝗿(s̲t̲r̲)
returns a copy of s̲t̲r̲ with all upper-case characters translated
to their corresponding lower-case equivalents.
𝘁𝗼𝘂𝗽𝗽𝗲𝗿(s̲t̲r̲)
returns a copy of s̲t̲r̲ with all lower-case characters translated
to their corresponding upper-case equivalents.
The ``function'' 𝗴𝗲𝘁𝗹𝗶𝗻𝗲 sets $𝟬 to the next input record from the cur‐
rent input file; 𝗴𝗲𝘁𝗹𝗶𝗻𝗲 < f̲i̲l̲e̲ sets $𝟬 to the next record from f̲i̲l̲e̲.
𝗴𝗲𝘁𝗹𝗶𝗻𝗲 x̲ sets variable x̲ instead. Finally, c̲m̲d̲ | 𝗴𝗲𝘁𝗹𝗶𝗻𝗲 pipes the out‐
put of c̲m̲d̲ into 𝗴𝗲𝘁𝗹𝗶𝗻𝗲; each call of 𝗴𝗲𝘁𝗹𝗶𝗻𝗲 returns the next line of
output from c̲m̲d̲. In all cases, 𝗴𝗲𝘁𝗹𝗶𝗻𝗲 returns 1 for a successful input,
0 for end of file, and -1 for an error.
Patterns are arbitrary Boolean combinations (with ! || &&) of regular ex‐
pressions and relational expressions. Regular expressions are as in
e̲g̲r̲e̲p̲; see g̲r̲e̲p̲(1). Isolated regular expressions in a pattern apply to
the entire line. Regular expressions may also occur in relational ex‐
pressions, using the operators ~ and !~. /r̲e̲/ is a constant regular ex‐
pression; any string (constant or variable) may be used as a regular ex‐
pression, except in the position of an isolated regular expression in a
pattern.
A pattern may consist of two patterns separated by a comma; in this case,
the action is performed for all lines from an occurrence of the first
pattern though an occurrence of the second.
A relational expression is one of the following:
e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲ m̲a̲t̲c̲h̲o̲p̲ r̲e̲g̲u̲l̲a̲r̲-̲e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲
e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲ r̲e̲l̲o̲p̲ e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲
e̲x̲p̲r̲e̲s̲s̲i̲o̲n̲ 𝗶𝗻 a̲r̲r̲a̲y̲-̲n̲a̲m̲e̲
(e̲x̲p̲r̲,e̲x̲p̲r̲,̲.̲.̲.̲) 𝗶𝗻 a̲r̲r̲a̲y̲-̲n̲a̲m̲e̲
where a r̲e̲l̲o̲p̲ is any of the six relational operators in C, and a m̲a̲t̲c̲h̲o̲p̲
is either ~ (matches) or !~ (does not match). A conditional is an arith‐
metic expression, a relational expression, or a Boolean combination of
these.
The special patterns 𝐁𝐄𝐆𝐈𝐍 and 𝐄𝐍𝐃 may be used to capture control before
the first input line is read and after the last. 𝐁𝐄𝐆𝐈𝐍 and 𝐄𝐍𝐃 do not
combine with other patterns. They may appear multiple times in a program
and execute in the order they are read by a̲w̲k̲.
Variable names with special meanings:
𝐀𝐑𝐆𝐂 argument count, assignable.
𝐀𝐑𝐆𝐕 argument array, assignable; non-null members are taken as file‐
names.
𝐂𝐎𝐍𝐕𝐅𝐌𝐓 conversion format used when converting numbers (default %.𝟲𝗴).
𝐄𝐍𝐕𝐈𝐑𝐎𝐍 array of environment variables; subscripts are names.
𝐅𝐈𝐋𝐄𝐍𝐀𝐌𝐄 the name of the current input file.
𝐅𝐍𝐑 ordinal number of the current record in the current file.
𝐅𝐒 regular expression used to separate fields; also settable by
option -𝐅f̲s̲.
𝐍𝐅 number of fields in the current record.
𝐍𝐑 ordinal number of the current record.
𝐎𝐅𝐌𝐓 output format for numbers (default %.𝟲𝗴).
𝐎𝐅𝐒 output field separator (default space).
𝐎𝐑𝐒 output record separator (default newline).
𝐑𝐋𝐄𝐍𝐆𝐓𝐇 the length of a string matched by 𝗺𝗮𝘁𝗰𝗵.
𝐑𝐒 input record separator (default newline). If empty, blank
lines separate records. If more than one character long, 𝐑𝐒 is
treated as a regular expression, and records are separated by
text matching the expression.
𝐑𝐒𝐓𝐀𝐑𝐓 the start position of a string matched by 𝗺𝗮𝘁𝗰𝗵.
𝐒𝐔𝐁𝐒𝐄𝐏 separates multiple subscripts (default 034).
Functions may be defined (at the position of a pattern-action statement)
thus:
𝗳𝘂𝗻𝗰𝘁𝗶𝗼𝗻 𝗳𝗼𝗼(𝗮, 𝗯, 𝗰) { ...; 𝗿𝗲𝘁𝘂𝗿𝗻 𝘅 }
Parameters are passed by value if scalar and by reference if array name;
functions may be called recursively. Parameters are local to the func‐
tion; all other variables are global. Thus local variables may be cre‐
ated by providing excess parameters in the function definition.
𝐄𝐍𝐕𝐈𝐑𝐎𝐍𝐌𝐄𝐍𝐓 𝐕𝐀𝐑𝐈𝐀𝐁𝐋𝐄𝐒
If 𝐏𝐎𝐒𝐈𝐗𝐋𝐘_𝐂𝐎𝐑𝐑𝐄𝐂𝐓 is set in the environment, then a̲w̲k̲ follows the POSIX
rules for 𝘀𝘂𝗯 and 𝗴𝘀𝘂𝗯 with respect to consecutive backslashes and amper‐
sands.
𝐄𝐗𝐀𝐌𝐏𝐋𝐄𝐒
length($0) > 72
Print lines longer than 72 characters.
{ print $2, $1 }
Print first two fields in opposite order.
BEGIN { FS = ",[ \t]*|[ \t]+" }
{ print $2, $1 }
Same, with input fields separated by comma and/or spaces and tabs.
{ s += $1 }
END { print "sum is", s, " average is", s/NR }
Add up first column, print sum and average.
/start/, /stop/
Print all lines between start/stop pairs.
BEGIN { # Simulate echo(1)
for (i = 1; i < ARGC; i++) printf "%s ", ARGV[i]
printf "\n"
exit }

𝐁𝐔𝐆𝐒
There are no explicit conversions between numbers and strings. To force
an expression to be treated as a number add 0 to it; to force it to be
treated as a string concatenate "" to it.
The scope rules for variables in functions are a botch; the syntax is
worse.
Only eight-bit characters sets are handled correctly.
𝐔𝐍𝐔𝐒𝐔𝐀𝐋 𝐅𝐋𝐎𝐀𝐓𝐈𝐍𝐆-𝐏𝐎𝐈𝐍𝐓 𝐕𝐀𝐋𝐔𝐄𝐒
A̲w̲k̲ was designed before IEEE 754 arithmetic defined Not-A-Number (NaN)
and Infinity values, which are supported by all modern floating-point
hardware.
Because a̲w̲k̲ uses s̲t̲r̲t̲o̲d̲(3) and a̲t̲o̲f̲(3) to convert string values to dou‐
ble-precision floating-point values, modern C libraries also convert
strings starting with 𝗶𝗻𝗳 and 𝗻𝗮𝗻 into infinity and NaN values respec‐
tively. This led to strange results, with something like this:
echo nancy | awk '{ print $1 + 0 }'
printing 𝗻𝗮𝗻 instead of zero.
A̲w̲k̲ now follows GNU AWK, and prefilters string values before attempting
to convert them to numbers, as follows:
H̲e̲x̲a̲d̲e̲c̲i̲m̲a̲l̲ v̲a̲l̲u̲e̲s̲
Hexadecimal values (allowed since C99) convert to zero, as they
did prior to C99.
N̲a̲N̲ v̲a̲l̲u̲e̲s̲
The two strings +𝗻𝗮𝗻 and -𝗻𝗮𝗻 (case independent) convert to NaN.
No others do. (NaNs can have signs.)
I̲n̲f̲i̲n̲i̲t̲y̲ v̲a̲l̲u̲e̲s̲
The two strings +𝗶𝗻𝗳 and -𝗶𝗻𝗳 (case independent) convert to posi‐
tive and negative infinity, respectively. No others do.
