Command History
FTOS maintains a history of previously-entered commands for each mode. For example:
• When you are in EXEC mode, the UP and DOWN arrow keys display the previously-entered EXEC
mode commands.
• When you are in CONFIGURATION mode, the UP or DOWN arrows keys recall the
previously-entered CONFIGURATION mode commands.
Filtering show Command Outputs
Filter the output of a show command to display specific information by adding | [except | find | grep | no-more
| save
] specified_text after the command. The variable specified_text is the text for which you are filtering and
it IS case sensitive unless the
ignore-case sub-option is implemented.
Starting with FTOS 7.8.1.0, the
grep command accepts an ignore-case sub-option that forces the search to
case-insensitive. For example, the commands:
•
show run | grep Ethernet returns a search result with instances containing a capitalized “Ethernet,” such
as interface GigabitEthernet 0/0.
•
show run | grep ethernet would not return that search result because it only searches for instances
containing a non-capitalized “ethernet.”
Executing the command
show run | grep Ethernet ignore-case would return instances containing both
“Ethernet” and “ethernet.”
•
grep displays only the lines containing specified text. The following example shows this command
used in combination with the command
show linecard all.
CNTL-N Return to more recent commands in the history buffer after recalling commands with CTRL-P or the
UP arrow key.
CNTL-P Recalls commands, beginning with the last command
CNTL-R Re-enters the previous command.
CNTL-U Deletes the line.
CNTL-W Deletes the previous word.
CNTL-X Deletes the line.
CNTL-Z Ends continuous scrolling of command outputs.
Esc B Moves the cursor back one word.
Esc F Moves the cursor forward one word.
Esc D Deletes all characters from the cursor to the end of the word.
