newform - change the format of a text file
newform [-s] [-itabspec]
[-otabspec] [-bn] [-en]
[-pn] [-an] [-f] [-cchar]
[-ln] [filename]...
newform reads lines from the named filenames, or the
standard 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.
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 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 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
- -itabspec
- Input tab specification: expands tabs to spaces, according to the tab
specifications given. Tabspec recognizes all tab specification
forms described in tabs(1). In addition, tabspec may be
-, in which newform assumes that the tab specification is to
be found in the first line read from the standard input (see
fspec(5)). 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 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
filename
- -en
- Same as -bn except that characters are truncated 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 necessary to obtain the
effective line length.
- -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 specification 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 characters. 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 character (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.
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.
- "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) may not contain a
tabspec referencing another file (or standard input).
csplit(1), tabs(1), fspec(5)
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.
