hi everyone, how do you get the terminal to predict commands as you type (like t9)? i've seen in various videos that use tabs and arrows, but nothing happens here
thank you

hi everyone, how do you get the terminal to predict commands as you type (like t9)? i've seen in various videos that use tabs and arrows, but nothing happens here
thank you

With bash, which you're probably using, hit TAB twice, sometimes, like

Code: Select all

$ li TAB TAB
libnetcfg                    lintian                      linux-version
libwacom-list-local-devices  lintian-info      ...

to see those commands; then add, say, an n, like lin TAB TAB.

If two tabs doesn't do it, check your ~/.bashrc file to make sure it has something like this:

Code: Select all

# enable programmable completion features (you don't need to enable
# this, if it's already enabled in /etc/bash.bashrc and /etc/profile
# sources /etc/bash.bashrc).
if ! shopt -oq posix; then
  if [ -f /usr/share/bash-completion/bash_completion ]; then
    . /usr/share/bash-completion/bash_completion
  elif [ -f /etc/bash_completion ]; then
    . /etc/bash_completion
  fi
fi

hello, thanks, inside the file, it actually says the same thing you sent, maybe I was wrong, I pressed TAB only once, instead of TAB TAB. 
# sources /etc/bash.bashrc).

  if [ -f /usr/share/bash-completion/bash_completion ]; then
