NAME
diffmk - Marks differences between files SYNOPSIS
diffmk [-b] [-ab'mark'] [-ae'mark'] [-cb'mark'] [-ce'mark'] [-db'mark'] [-de'mark'] file1 file2 The diffmk command compares two versions of a file and creates a new file that marks the differences. OPTIONS
Uses mark to mark where added lines begin. Uses mark to mark where added lines end. Ignores differences that are only changes in tabs or spaces on a line. Uses mark to mark where changed lines begin. Uses mark to mark where changed lines end. Uses mark to mark where deleted lines begin. Uses mark to mark where deleted lines end. DESCRIPTION
The file1 and file2 variables are the old and new versions of the file, respectively. The diffmk command compares them and writes a new version to standard output, which can be redirected to a file. This output contains the lines of file2 marked with nroff change mark requests (.mc), or with the marks you specify with the -ab, -ae, -cb, -ce, -db, and -de options. When output containing requests is formatted with nroff, changed or inserted lines are marked by a | (vertical bar) at the right margin of each line. An * (asterisk) indicates that a line was deleted. If the DIFFMARK environment variable is defined, it names a command string that diffmk uses to compare the files. (Normally, diffmk uses the diff command.) For example, you might set DIFFMARK to diff -h in order to better handle extremely large files. EXAMPLES
To mark the differences between two versions of a text file, enter: diffmk -ab'>I:' -ae'<I' -cb'>C' -ce'<C' -db'>D' -de'<D' chap1.old chap1 >chap1.diffs This causes diffmk to create a copy of chap1 called chap1.diffs, showing differences between chap1.old and chap1. Additions of one or more lines are marked with >I and <I, changed lines are marked with >C and <C, and deletions are marked with >D and <D. To mark differences with nroff requests, enter: diffmk chap1.old chap1 > chap1.nroff This produces a copy of chap1 called chap1.nroff containing nroff change mark requests to identify text that was added to, changed, or deleted from chap1.old. To use different nroff marking requests and ignore changes in white space, enter: diffmk -b -cb'.mc %' chap1.old chap1 > chap1.nroff This imbeds commands that mark changes with % (percent sign), additions with | (the default, because no -a option is specified), and deletions with * (the default). It does not mark changes that only involve a different number of spaces or tabs between words (-b). SEE ALSO

NAME
nl - Numbers lines in a file SYNOPSIS
nl [-b type] [-d delimiter1[delimiter2]] [-f type] [-h type] [-i number] [-l number] [-n format] [-p] [-s [separator]] [-vnumber] [-wnum- ber] [file] STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: nl: XCU5.0 Refer to the standards(5) reference page for more information about industry standards and associated tags. OPTIONS
Use the following options to change the default settings. Specifies which body section lines to number. The recognized types are as fol- lows: Numbers all lines. Number only non-empty lines. Does not number any lines. Numbers only those lines containing the specified pat- tern. The full range of regular expressions is supported for pattern. The default for type is t. Uses delimiter1 and delimiter2 as the delimiters for the start of a logical page section. The default characters are : (backslash followed by a colon). You can specify either one or two characters after the -d option. If you want to use a backslash as a delimiter, enter two back- slashes (\). If you specify only one character, it is used as start of a logical page, and the end delimiter remains the default. Specifies which logical page footer lines to number. The types recognized are the same as in -b type. The default for type is n. Specifies which logical page header lines to number. The types recognized are the same as in -b type. The default for type is n. Increments logical page line numbers by number. The default is 1. Counts number blank lines as 1. You must use one or more of the "-ba", "-fa", and "-ha" options with this option for it to be effective. For example, -l3 will only number the third adjacent blank. The default is 1. Specifies format as the line numbering format. Recognized formats are as fol- lows: Left justified, leading zeroes are suppressed. Right justified, leading zeroes are suppressed (default). Right justified, leading zeroes are kept. Ignores logical page delimiters (does not restart numbering). Separates text from line numbers with the separator string. The default value of separator is a tab character. [Tru64 UNIX] If you enter -s without an argument, there is no separation between the line number and its text. Sets the initial logical page line number to number. Specifies number as the number of digits in the line number. The default value of number is 6. OPERANDS
The path name of a file in which the lines are to be numbered. If file is not specified, standard input is used. DESCRIPTION
The nl command reads file (standard input by default), numbers the lines in the input, and writes the numbered lines to standard output. In the output, nl numbers the lines on the left, according to the options you specify on the command line. The input text must be written in logical pages. Each logical page has a header, a body, and a footer section (sections can be empty). Unless you use the -p option, nl resets the line numbers at the start of each logical page. You can set line numbering options indepen- dently for the header, body, and footer sections (for example, no numbering of header and footer lines while numbering text lines only in the body). Signal the start of logical page sections with lines in file that contain nothing but the following delimiter characters (assuming the default delimiters--see the description of the -d option): Line Contents Start of ::: Header :: Body : Footer You can name only one file on the command line. You can list the options and the file name in any order. EXIT STATUS
The following exit values are returned: Successful completion. An error occurred. EXAMPLES
To number only the nonblank lines, enter: nl chap1 This displays a numbered listing of chap1, numbering only the nonblank lines in the body sections. If chap1 contains no :: :, : :, or : delimiters, then the entire file is considered the body. To number all lines, enter: nl -ba chap1 This numbers all the lines in the body sections, including blank lines. This form of the nl command is adequate for most uses. To specify a different line number format, enter: nl -i10 -nrz -s:: -v10 -w4 chap1 This numbers the lines of chap1, starting with 10 (-v10) and counting by 10s (-i10). It displays four digits for each number (-w4), including leading zeroes (-nrz). The line numbers are separated from the text by two colons (-s::). For example, if chap1 contains the following text: A not-so-important note to remember: You can't kill time without injuring eternity. then the numbered listing is as follows: 0010::A not-so-important note to remember: 0020::You can't kill time without injuring eternity. Notice that the blank line was not numbered. To do this, use the -ba option as shown in Example 2. ENVIRONMENT VARIABLES
The following environment variables affect the execution of nl: Provides a default value for the internationalization variables that are unset or null. If LANG is unset or null, the corresponding value from the default locale is used. If any of the internationalization vari- ables contain an invalid setting, the utility behaves as if none of the variables had been defined. If set to a non-empty string value, overrides the values of all the other internationalization variables. Determines the locale for the interpretation of sequences of bytes of text data as characters (for example, single-byte as opposed to multibyte characters in arguments and input files), the behavior of classes within regular expressions, and for deciding which characters are in character class graph. Determines the locale for the format and contents of diagnostic messages written to standard error. Determines the location of message catalogues for the processing of LC_MES- SAGES. SEE ALSO
