NEWFORM(1)                           SysV                           NEWFORM(1)



NAME
     newform - change the format of a text file

SYNOPSIS
     newform [-s] [-i tabspec] [-o tabspec] [-b n] [-e n] [ -p n] [-a n] [-f]
     [-c char] [-l n] [files]

DESCRIPTION
     newform reads lines from the named files, 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 files.  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 files on the command line.

OPTIONS
     -s        Shears off leading characters on each line up to the first tab
               and places up to eight of the sheared characters at the end of
               the line.  If more than eight 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, if you
               specify a simple dash (-) for the value of tabspec, 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 -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 that tabs and backspaces
               are considered to be one character (use -i to expand tabs to
               spaces).   The -l1 option must be used to set the effective
               line length shorter than any existing line in the file so that
               the -b option is activated.

BUGS
     The newform command 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.

     The newform command 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.

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) may not contain a tabspec referencing
                                  another file (or standard input).

     0 - normal execution
     1 - for any error
