fc Command in Linux with Examples

Last Updated : 22 Mar, 2024

As we all know that LINUX is command friendly and while working on LINUX, you may deal with very long commands that may include long paths or really difficult syntax, and imagine what if working with such commands you do a minor mistake which will require re-writing of the entire command synopsis and its arguments in order to execute it again successfully. Now, there are two solutions to this - either re-write the entire syntax or simply use

fc

command that allows you to

edit

and

re-execute

the commands previously entered to a shell without re-writing them again. This command line utility really comes to help while editing long commands. So, the

fc

command is used to list, edit or re-execute the commands previously entered into an interactive shell. Here's the syntax of fc command :

 
//syntax of fc command
fc [-e ename] [-lnr] [first] [last]

           or
fc -s [pat=rep] [command]

where the

-lnr

refers to the options available for

fc

and

-e ename

refers to the editor you want to use for editing.

first

and

last

here is for specifying the range .

To easily understand the use of fc command and how does it work let's take a simple example where you want to change your working directory to

kt/kartik/thakral

and by mistake while changing your directory you write

karik

instead of

kartik

, in this case you can simply use

fc command

to edit the previously entered path. After you enter the incorrect directory path you'll see something like this :

then you can just simply type

fc

command and after writing fc command your editor will open up so that you can now edit the previously entered command like shown below :

after editing your path you can exit your editor and after exiting

fc

command will

re-execute

the

cd kt/kartik/thakral

like shown below :

• fc command is the best way to edit the previously entered commands in the case of a minor mistake without re-writing the entire command syntax and argument again.
• It can also be used to list the previously entered commands in the terminal which can be helpful in case you are working with some new commands.
• fc command in a way lets you know the command history.
