Displaying and Editing Previous Commands

Correcting Mistakes Using the FC Command

The FC command allows you to display and edit a command you entered previously in

the current session. This feature is handy for correcting typographical errors or for

executing several similar commands.

FC supports the same search options as the ? and ! commands. Y

ou can request a

command line by line number, relative line number, or text string. If you enter FC by

itself, the last command line you entered is displayed.

When you execute FC, the specified command line is displayed, and the cursor is

positioned below that command on a command-editing line. Y

ou can then use the

displayed command line as a guide for creating a new command.

FC has four subcommands that you can use in the command-editing line. Enter these

subcommands on the editing line to modify the characters directly above them in the

redisplayed command line. FC supports these subcommands:

deletes the character directly above d.

istring

inserts string before the character directly above i.

rstring

replaces the characters in the command line with string. The first character

replaced is the character directly above r.

string

replaces the characters in the command line directly above the string characters

with string. This is an implicit replace subcommand. It works the same as the r

subcommand.

// (2 backslashes)

ends the current string and allows you to enter another subcommand in the editing

mplate.

The following example illustrates use of the FC command. In this example, the FC

command retrieves the command at line number 18 and then displays the editing

template on the next line. The d subcommand is then used to delete the characters

PROG, and the i subcommand is used to insert the characters 03 so that the file name

Note. On the command-editing line, use only the spacebar and backspace key to move the

cursor. Do not use the arrow keys.

Note. FC recognizes any string in the editing template line

that does not begin with d, i, or r as

an implicit replacement string.
