DESCRIPTION
newform
reads lines from the named
files,
or standard input if no input file is named,
and reproduces the lines on standard output.
Lines are reformatted in accordance with
command line options in effect.
Command line options can appear in any order,
can be repeated, and can be intermingled with the optional
files.
Command line options are processed in the order specified.
This means that option sequences such as
-e15 -l60
yield results different from
-l60 -e15.
Options are applied to all files on the command line.
Options
newform
recognizes the following options:
- -an
Same as
-pn
except characters are appended to the end of a line.
- -bn
Truncate
n
characters from the beginning of the line
when the line length is greater than the effective line length (see
-ln).
The default is to truncate the number of characters 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 file-name
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.
- -ck
Change the prefix/append character to
k.
The default character for
k
is a space.
- -en
Same as
-bn
except that characters are truncated from the end of the 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
contains the default specification of
-o8.
- -itabspec
Input tab specification:
expands tabs to spaces, according to the tab specifications given.
The
tabspec
recognizes all tab specification forms
described in
tabs(1).
In addition,
tabspec
can be
--,
in which
newform
assumes that the tab specification is to be found
in the first line read from the standard input (see
fspec(4)).
If no
tabspec
is given,
tabspec
defaults to
-o8.
A
tabspec
of
-o0
expects no tabs; if any are found, they are treated as
-o1.
- -ln
Set the effective line length to
n
characters.
If
n
is not entered,
-l
defaults to 72.
The default line length without the
-l
option is 80 characters.
Note that tabs and backspaces are treated as single characters (use
-i
to expand tabs to spaces).
- -otabspec
Output tab specification:
replaces spaces with tabs, according to the tab specifications given.
The tab specifications are the same as for
-itabspec.
If no
tabspec
is given,
tabspec
defaults to
-o8.
A
tabspec
of
-o0
means that no spaces will be converted to tabs on output.
- -pn
Prefix
n
characters (see
-ck)
to the beginning of a line
when the line length is less than the effective line length.
The default is to prefix the number of characters necessary
to obtain the effective line length.
- -s
Shear off leading characters on each line up to the first tab and
place up to 8 of the sheared characters at the end of the line.
If more than 8 characters (not counting the first tab) are sheared,
the eighth character is replaced by a
*
and any characters to the right of it are discarded.
The first tab is always discarded.
An error message and program exit 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 file-name
RETURN VALUE
newform
returns one of the following values:
- 0
No errors encountered.
- 1
An error occurred.
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 specified tab stops are not ascending.
- tabspec indirection illegal
A
tabspec
read from a file (or standard input) must not contain a
tabspec
referencing another file (or standard input).
WARNINGS
newform
normally only keeps track of physical characters;
however, for the
-i
and
-o
options,
newform
keeps track of backspaces in order to line up tabs
in the appropriate logical columns.
newform
does 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.
