Keyboard shortcut for last entered param in command line ?

I watched a linux tut video and noticed some cool trick. Can you explain how he managed to insert string "/sbin/mkfs.ext2" at 0:30 ? He hadn't selected it before. Is it some sort of keyboard shortcut for last entered param ?

I don't speak that language. Maybe Ctrl+P for last entered.

You can print last argument of previously run command using ALT + . (ALT key plus dot) keyboard combination.

Code:

bash$ ls -ld /home/jack/test

bash$ cd (ALT + .)

And it will print:

Code:

bash$ cd /home/jack/test

Note: CTRL+P will print previously run command, not last argument of previous cmd.

Ctrl+Alt+y would also do it. Reference here.

Simply you can use up arrow key to get last command.
And using exclamatory(!) symbol also you can excecute the commands of previous command(s).
For example I have ran 3 commands

Code:

vi /etc/samba/smb.conf  -->1st

ping -c5 google.com    -->2nd

tail -f /var/log/syslog -->3rd

Now if I again want to open /etc/samba/smb.conf file, just type & hit enter

Code:

!v

Using history numbers also you can run any previosly excecuted commands

Code:

#history

2023  cal

2024  man dig

2025  nslookup localhost

2026  echo $?

2027  whoami

2028  w

2029  who

2030  tree -d /etc

2031  vi /etc/samba/smb.conf 

2032  ping -c5 google.com

2033  tail -f /var/log/syslog

If you want to run command of history number 2030 just type

Code:

!2030

Yes -- about re-running complete commands. The OP was about pasting the last argument of the last command.
