User Commands newform(1)
NAME
newform - change the format of a text file
SYNOPSIS
newform [-s] [-itabspec] [-otabspec] [-bn] [-en] [-pn] [-an]
[-f] [-cchar] [-ln] [filename...]
DESCRIPTION
newform reads lines from the named filenames, or the stan-
dard input if no input file is named, and reproduces the
lines on the standard output. Lines are reformatted in
accordance with command line options in effect.
Except for -s, command line options may appear in any order,
may be repeated, and may be intermingled with the optional
filenames. Command line options are processed in the order
specified. This means that option sequences like ``-e15
-l60'' will yield results different from ``-l60 -e15''.
Options are applied to all filenames on the command line.
OPTIONS
The following options are supported:
-s Shears off leading characters on each line
up to the first tab and places up to 8 of
the sheared characters at the end of the
line. If more than 8 characters (not count-
ing the first tab) are sheared, the eighth
character is replaced by a * and any charac-
ters to the right of it are discarded. The
first tab is always discarded.
An error message and program exit will occur
if this option is used on a file without a
tab on each line. The characters sheared off
are saved internally until all other options
specified are applied to that line. The
characters are then added at the end of the
processed line.
For example, to convert a file with leading
digits, one or more tabs, and text on each
line, to a file beginning with the text, all
tabs after the first expanded to spaces,
padded with spaces out to column 72 (or
truncated to column 72), and the leading
digits placed starting at column 73, the
command would be:
newform -s -i -l -a -e filename

User Commands newform(1)
-itabspec Input tab specification: expands tabs to
spaces, according to the tab specifications
given. Tabspec recognizes all tab specifica-
tion forms described in tabs(1). In addi-
tion, tabspec may be -, in which newform
assumes that the tab specification is to be
found in the first line read from the stan-
dard input (see fspec(4)). If no tabspec is
given, tabspec defaults to -8. A tabspec of
-0 expects no tabs; if any are found, they
are treated as -1.
-otabspec Output tab specification: replaces spaces by
tabs, according to the tab specifications
given. The tab specifications are the same
as for -itabspec. If no tabspec is given,
tabspec defaults to -8. A tabspec of -0
means that no spaces will be converted to
tabs on output.
-bn Truncate n characters from the beginning of
the line when the line length is greater
than the effective line length (see -ln).
Default is to truncate the number of charac-
ters necessary to obtain the effective line
length. The default value is used when -b
with no n is used. This option can be used
to delete the sequence numbers from a COBOL
program as follows:
newform -l1 -b7 filename
-en Same as -bn except that characters are trun-
cated from the end of the line.
-pn Prefix n characters (see -cchar) to the
beginning of a line when the line length is
less than the effective line length. Default
is to prefix the number of characters neces-
sary to obtain the effective line length.

User Commands newform(1)
-an Same as -pn except characters are appended
to the end of a line.
-f Write the tab specification format line on
the standard output before any other lines
are output. The tab specification format
line which is printed will correspond to the
format specified in the last -o option. If
no -o option is specified, the line which is
printed will contain the default specifica-
tion of -8.
-cchar Change the prefix/append character to char.
Default character for char is a space.
-ln Set the effective line length to n charac-
ters. If n is not entered, -l defaults to
72. The default line length without the -l
option is 80 characters. Note: Tabs and
backspaces are considered to be one charac-
ter (use -i to expand tabs to spaces).
The -l1 must be used to set the effective
line length shorter than any existing line
in the file so that the -b option is
activated.
OPERANDS
The following operand is supported:
filename Input file
EXIT STATUS
The following exit values are returned:
0 Successful operation.
1 Operation failed.

DIAGNOSTICS
All diagnostics are fatal.
usage: ...
newform was called with a bad option.
"not -s format"
There was no tab on one line.
"can't open file"
Self-explanatory.
"internal line too long"
A line exceeds 512 characters after being expanded in
the internal work buffer.
"tabspec in error"
A tab specification is incorrectly formatted, or speci-
fied tab stops are not ascending.
"tabspec indirection illegal"
A tabspec read from a file (or standard input) may not
contain a tabspec referencing another file (or standard

input).
NOTES
newform normally only keeps track of physical characters;
however, for the -i and -o options, newform will keep track
of backspaces in order to line up tabs in the appropriate
logical columns.
newform will not prompt the user if a tabspec is to be read
from the standard input (by use of -i- or -o-).
If the -f option is used, and the last -o option specified
was -o-, and was preceded by either a -o- or a -i-, the tab
specification format line will be incorrect.
