\b0 scans each input file for lines that match any of a set of patterns specified in prog. With each pattern in prog there can be an associated action that will be performed when a line of a file matches the pattern. The set of patterns may appear literally as prog, or in a file specified as -f file.\
Files are read in order; if there are no files, the standard input is read. The file name `-' means the standard input. Each line is matched against the pattern portion of every pattern-action statement; the associated action is performed for each matched pattern.\
An input line is made up of fields separated by white space. (This default can be changed by using FS, vide infra.) The fields are denoted $1, $2, ... ; $0 refers to the entire line.\
A pattern-action statement has the form\
\b pattern \{ action \}
\b0 \
A missing
\b \{ action \}
\b0 means print the line; a missing pattern always matches.\
An action is a sequence of statements. A statement can be one of the following:\
\b if ( conditional ) statement [ else statement ]
\b0 \
\b while ( conditional ) statement
\b0 \
\b for ( expression ; conditional ; expression ) statement\
break\
continue\
\{ [ statement ] ... \}\
variable = expression\
print [ expression-list ] [ >expression ]\
printf format [ , expression-list ] [ >expression ]
\b0 \
\b next #
\b0 skip remaining patterns on this input line\
\b exit #
\b0 skip the rest of the input\
Statements are terminated by semicolons, newlines or right braces. An empty expression-list stands for the whole line. Expressions take on string or numeric values as appropriate, and are built using the operators +, -, *, /, %, and concatenation (indicated by a blank). The C operators ++, --, +=, -=, *=, /=, and %= are also available in expressions. Variables may be scalars, array elements (denoted x[i]) 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. String constants are quoted "...".\
The print statement prints its arguments on the standard output (or on a file if >file is present), separated by the current output field separator, and terminated by the output record separator. The printf statement formats its expression list according to the format (see printf(3S)).\
The built-in function length returns the length of its argument taken as a string, or of the whole line if no argument. There are also built-in functions exp, log, sqrt, and int. The last truncates its argument to an integer. substr(s, m, n) returns the n-character substring of s that begins at position m. The function sprintf(fmt, expr, expr, ...) formats the expressions according to the printf(3S) format given by fmt and returns the resulting string.\
Patterns are arbitrary Boolean combinations (!, ||, &&, and parentheses) of regular expressions and relational expressions. Regular expressions must be surrounded by slashes and are as in egrep. Isolated regular expressions in a pattern apply to the entire line. Regular expressions may also occur in relational expressions.\
A pattern may consist of two patterns separated by a comma; in this case, the action is performed for all lines between an occurrence of the first pattern and the next occurrence of the second.\
where a relop is any of the six relational operators in C, and a matchop is either ~ (for contains) or !~ (for does not contain). A conditional is an arithmetic 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 must be the first pattern, END the last.\
A single character c may be used to separate the fields by starting the program with\
BEGIN \{ FS = "c" \}\
or by using the -Fc option.\
Other variable names with special meanings include NF, the number of fields in the current record; NR, the ordinal number of the current record; FILENAME, the name of the current input file; OFS, the output field separator (default blank); ORS, the output record separator (default newline); and OFMT, the output format for numbers (default "%.6g").\
EXAMPLES\
Print lines longer than 72 characters:\
\b length > 72
\b0 \
Print first two fields in opposite order:\
\b \{ print $2, $1 \}
\b0 \
Add up first column, print sum and average:\
\b \{ s += $1 \} END \{ print "sum is", s, " average is", s/NR \}
\b0 \
Print fields in reverse order:\
\b \{ for (i = NF; i > 0; --i) print $i \}
\b0 \
Print all lines between start/stop pairs:\
\b /start/, /stop/
\b0 \
Print all lines whose first field is different from previous one:\
\b $1 != prev \{ print; prev = $1 \}

\b0 reads the standard input and writes the standard output. It performs the line overlays implied by reverse line feeds (ESC-7 in ASCII) and by forward and reverse half line feeds (ESC-9 and ESC-8). Col is particularly useful for filtering multicolumn output made with the `.rt' command of nroff and output resulting from use of the tbl(1) preprocessor.\
Although col accepts half line motions in its input, it normally does not emit them on output. Instead, text that would appear between lines is moved to the next lower full line boundary. This treatment can be suppressed by the -f (fine) option; in this case the output from col may contain forward half line feeds (ESC-9), but will still never contain either kind of reverse line motion.\
If the -b option is given, col assumes that the output device in use is not capable of backspacing. In this case, if several characters are to appear in the same place, only the last one read will be taken.\
The control characters SO (ASCII code 017), and SI (016) are assumed to start and end text in an alternate character set. The character set (primary or alternate) associated with each printing character read is remembered; on output, SO and SI characters are generated where necessary to maintain the correct treatment of each character.\
If the -h option is given, col converts white space to tabs to shorten printing time.\
All control characters are removed from the input except space, backspace, tab, return, newline, ESC (033) followed by one of 7, 8, 9, SI, SO, and VT (013). This last character is an alternate form of full reverse line feed, for compatibility with some other hardware conventions. All other non-printing characters are ignored.

\b0 provides virtual half-line and reverse line feed sequences for terminals without such capability, and on which overstriking is destructive. Half-line characters and underlining (changed to dashing `-') are placed on new lines in between the normal output lines.\
\b0 removes selected columns from a file. Input is taken from standard input. Output is sent to standard output. If called with one parameter the columns of each line will be removed starting with the specified column. If called with two parameters the columns from the first column to the last column will be removed. Column numbering starts with column 1.

\b emacs
\b0 was written by the author of the original (PDP-10) Emacs, Richard Stallman. Its functionality encompasses everything other Emacs editors do, and it's easily extensible since its editing commands are written in Lisp. Emacs has an extensive interactive help facility, but the facility assumes that you know how to manipulate Emacs windows and buffers. Control-h (backspace or Control-h) enters the Help facility. Help Tutorial (Control-h t) requests an interactive tutorial that can teach beginners the fundamentals of Emacs in a few minutes. Help Apropos (Control-h a) helps you find a command given its functionality; Help Character (Control-h c) yes describes a given character's effect; and Help Function (Control-h f) describes a given Lisp function specified by name. The Emacs Undo command can undo several steps of modification to your buffers, so it's easy to recover from editing mistakes. Special packages in GNU Emacs handle mail reading (RMail) and sending (Mail), outline editing (Outline), compiling (Compile), running subshells within Emacs windows (Shell), running a Lisp read-eval-print loop (Lisp-Interaction-Mode), and automated psychotherapy (Doctor). There is an extensive reference manual, but users of other versions of Emacs should have little trouble adapting even without a copy. Users new to Emacs will be able to use basic features fairly rapidly by studying the tutorial and using the self-documentation features.

\b0 is the root of a family of editors: edit, ex and vi. Ex is a superset of ed, with the most notable extension being a display editing facility. Display based editing is the focus of vi. If you have not used ed, or are a casual user, you will find that the editor edit is convenient for you. It avoids some of the complexities of ex used mostly by systems programmers and persons very familiar with ed. If you have a CRT terminal, you may wish to use a display based editor; in this case see vi(1), which is a command which focuses on the display editing portion of ex.

\b0 processes the named files or the standard input writing the standard output with tabs changed into blanks. Backspace characters are preserved into the output and decrement the column count for tab calculations. Expand is useful for pre-processing character files (before sorting, looking at specific columns, etc.) that contain tabs. If a single tabstop argument is given, then tabs are set tabstop spaces apart instead of the default 8. If multiple tabstops are given then the tabs are set at those specific columns.
\b0 is a filter which will fold the contents of the specified files, or the standard input if no files are specified, breaking the lines to have maximum width width. The default for width is 80. Width should be a multiple of 8 if tabs are present, or the tabs should be expanded using expand(1) before coming to fold.
