Command: edlin

EDLIN is a small line editor.


edlin [[drive][path]file] drive The drive letter, e.g. C: path The directory, e.g. \example\ file The file, e.g. test.txt.


A dollar sign in the following lists represents a string of characters. They may be enclosed in either single or double quotes and may contain the following escape sequences: \a alert \b backspace \e escape \f formfeed \t horizontal tab \v vertical tab \" double quote \' single quote \. period \\ backslash \xXX where X is a hex digit (0-9, a-f, A-F) - hexadecimal constant \dddd where d is a decimal digit (0-9) - decimal constant \OOO where O is an octal digit (0-7) - octal constant \^C control character In the following command lists, brackets [ ] represent optional constructs. The # symbol represents a line number, which is either a string of digits, a period (.) representing the current line, a dollar sign ($) representing the last line in the file, or a line number added or subtracted from another line number, so that .,.+1p prints the current line and the succeeding line. Edlin has the following internal commands (used while running edlin): # edit a single line a append [#],[#],#,[#]c copy a range of lines [#][,#]d delete a block of lines efilename exit (save and quit) [#]i insert mode [#][,#]l list lines [#],[#],#m move block [#][,#]p page q quit [#][,#][?]r$,$ replace string [#][,#][?]s$ search for substring [#]tfilename transfer file [#]wfilename write file # - EDIT A SINGLE LINE The edline program outputs the single line indicated by the number, and the next inputted line replaces the outputted line in the file. a - APPEND This command is equivalent to $+1i . [#],[#],#,[#]c - COPY A RANGE OF LINES This command copies a block of consecutive lines to another location in the buffer. The parameters are: * The first line you want to copy (default = current line) * The last line you want to copy (default = current line) * The line before which you want to insert the block of lines * The number of times you want to copy the block (default = 1) After edlin copies lines, you may use the l (list) command to see the correctly renumbered lines. [#][,#]d - DELETE A BLOCK OF LINES This command deletes a block of consecutive lines. The parameters are the first and last line of the block to be deleted. If you omit the second parameter, it deletes only the line specified in the first parameter. If you omit the first parameter, it deletes the block from the current line to the line specified in the second parameter (be sure to include the comma). Omitting both parameters causes the current line to be deleted. eFilename - SAVE AND QUIT This command is equivalent to: w filename followed by: q [#]i - INSERT MODE This command enters insert mode. Its parameter is the line number before which you want to insert lines. While inserting, escape sequences such as those above are legal to type in. To exit insert mode, type a period (.) on an otherwise blank line (if you need a line with just a period, escape it). After exiting insert mode, the line after the inserted text becomes the current line unless the insertion was appended to the end of the text, in which case the last line of the text becomes the new current line. [#][,#]l - LIST LINES This command lists lines of text on the screen. If you omit the first parameter, the command starts showing text beginning with 11 lines of text before the current line. Omitting the second parameter shows a page of text beginning with the line specified in the first parameter. Omitting both shows one page of text starting at 11 lines before the current line. In all cases, if the number of lines is larger than the number of lines in a page, the program will prompt after each page of lines. [#],[#],#m - MOVE BLOCK This command moves a block of text to the line before the number specified in the third parameter. It is similar to copying, then deleting the original block. [#][,#]p - PAGE This is similar to l except that the default page starts with the current line instead of 11 lines before. q - QUIT Close file being edited losing all changes and exit EDLIN. [#][,#][?]r$,$ - REPLACE STRING This command replaces all occurrences of the first string with the second between the two lines specified. An omitted first parameter starts the replacing at the line after the current line; an omitted second parameter stops the replacing at the last line of the file. The question mark sends a confirmation message before replacement. [#][,#][?]s$ - SEARCH FOR SUBSTRING This command searches for the first line containing the substring specified. Omitting the first parameter causes the search to start on the current line; omitting the second causes the search to stop at the end of the file. The question mark causes the search to send a confirmation message. Saying no to the confirmation message continues the search; saying yes ends it. The current line will be reset to the line where the search ended if it was successful. [#]tFilename - TRANSFER FILE This command causes the contents of the file to be inserted before the line number specified. If the line number is omitted, the default is the current line. [#]wFilename - WRITE FILE This command causes the first number of lines specified by the parameter to be written to the file specified. If the parameter is omitted, it will write all the lines in the buffer to the file.


EDLIN is a small line editor, written for FreeDOS as a functional clone of the old MS-DOS program EDLIN. It's main purpose is to create batch files and small programs. It differs from MS EDLIN in that first, it's free software, and second, the user interface is slightly different in a few places. The reason for the difference is so that the user does not have to type in control characters mandated by EDLIN's syntax. EDLIN supports NLS (national language support).


edlin c:\config.sys Opens the file config.sys for editing. edlin If no file is specified, edline begins with a blank document. I want to enter and save four sentences, one below the other. This is sentence four. This is sentence three. This is sentence three. This is sentence one. (from edlin's * prompt, with an empty buffer...) i This is sentence four. This is sentence three. This is sentence three. This is sentence one. . Now I want to save these four sentences in a .txt file at C:\test.txt wc:\test.txt Then I find out that the third sentence is wrong (correct: This is sentence two). How to correct and to save it? 3rthree,two wc:\test1.txt Then I want to add a fifth sentence at the beginning (This is sentence five). How to add it? 1i This is sentence five. . wc:\test2.txt I want to see if everything is correct. l I want to exit. q
