FC Command
FC Command
Use the FC command to retrieve, edit, and reexecute lines in the history buffer.
num
is a positive integer that refers to the specific command-line number you want to
retrieve from the history buffer.
- num
is a negative number that refers to a command line in the history buffer relative to
the current command line.
text
is the most recent command line in the history buffer that begins with the text you
specify. This text need only be as many characters as necessary to identify the
command line.
Consideration
When you enter the FC command, the specified command line is redisplayed (if you do
not specify a line, the most recent command line is redisplayed). A double period
prompt (..) appears below it.
Examples
Suppose that you are renaming the file JUNK to TESTFILE, and make a typing error in
the RENAME command on line 9. Rather than retype the whole line, type FC 9 to fix
the invalid command:
12> FC 9
12> RENMAE JUNK, TESTFILE
12..
You now see your invalid command redisplayed on the screen. The blank line at the
double period prompt is an editing template. In this template, you enter subcommands
that make corrections or additions to the command displayed above the template. The
rules for entering subcommands and for making corrections and additions are
described for the Editing Template on page 8-64.
After you enter the subcommands you want, press the RETURN key. Your edited
command and a new editing template then appear. If you want to make more
corrections to the edited command, you can enter more subcommands in the editing
template and then press RETURN. If the edited command is correct, you can
reexecute it by pressing RETURN without entering any subcommands.
