How to quickly add some space in the terminal?

There are a few options that spring to mind

1. Spacer lines:

   sl() { yes '' | head -"${1:-5}"; } # Use as "sl 10" or "sl" 

2. Pipe the output of your make through a pager:

   make {whatever} 2>&1 | less 

3. Run the entire session under screen. You can then Ctrl AEsc and scroll up through the buffer a page at a time using Ctrl B. Use ReturnReturn to exit scrollback mode

I wrote a little C program to print three lines of bricks across the terminal for this purpose. Not empty space, but it helps give visual separation in the same way, and stands out in verbose output that might have a bunch of vertical space. Swap out your favorite character to taste:

#include <termios.h> #include <sys/ioctl.h> #include <stdio.h> int main(int argc, char *argv[]) { struct winsize ws; ioctl(0, TIOCGWINSZ, &ws); int i=0; // square: \u25A0 // large square: \u2B1B // block: \u2588 for(;i<3*ws.ws_col;++i) printf("\u2588"); printf("\n"); return 0; } 

I have

alias five='echo -e "\n\n\n\n"' 

for that, you can further shorten the alias to your liking of course.

I trust you already have enough ways to abbreviate echo -e "\n\n\n\n\n\n", so I won't add to that. But you have another option: Many terminal emulators support searching, so you can go to the start of the last command by searching backwards for some part of your prompt. (Or for some known string in the output, but the prompt is always there.)

TBH I usually just do the same thing you've been doing-- my Return key repeats fast enough that it never bothered me much to just hold it down.

You can use clear multiple times (clear;clear) or just hold down Ctrl+L until you satisfy!

With zsh, you can try (fun with repeat):-

• repeat 5 clear
• repeat 20 echo
• repeat 50 printf '\n'

And of-course you may want to alias goaway='repeat 7 clear'.

Another approach could be to have some unique text in your prompt (I use $ followed by a non-breaking space (PS1=$'$\ua0')).

And configure your terminal emulator to scroll-back to it upon some key press.

For instance, with GNU screen, in ~/.screenrc:

defscrollback 5000 bindkey \033` eval copy "stuff k?$\240\r" 

Would map that to Alt+Backtick

bash script to print a custom number of newlines:

#!/bin/bash if [[ "$1" =~ ^[0-9]+$ ]] then for ((i=0; i<$1; i++)) do echo done exit 0 fi exit 1 

Name it (say script.bash) and put it in your $PATH (say in /usr/bin), run chmod +x /usr/bin/script.bash and call it with script.bash <number_of_lines>, or put it wherever you want, mark it as executable and add an alias to ~/.bashrc or ~/.bash_aliases:

alias script.bash='bash /path/to/script' 

You can change / shorten the name and the alias to your needs. It can also be modified to print a default number of lines if no argument is passed:

#!/bin/bash if ! [[ "$1" =~ ^[0-9]+$ ]] $1=5 fi for ((i=0; i<$1; i++)) do echo done 

This is sort of a sideways answer to your question, but I prefer using an inverted prompt (which stands out and is easy to spot) for just the purpose of quickly being able to determine where in the scrollback the last command was run.

You can invert your prompt's color (i.e. black text on white background) by adding the ANSI sequences <esc>[7m (invert) to the beginning of the prompt, and <esc>[0m (reset) to the end of it.

Most, more fancy shells (like bash and zsh) also keep track of the length of the prompt on screen, so you'll need to add some sugar to tell the shell that these sequences do not move the cursor forward. In zsh this is done using %{...%} while bash uses \[...\].

Thus, to invert your prompt in zsh use:

PROMPT=$'%{\e[7m%}'"${PROMPT% }"$'%{\e[0m%} ' 

and in bash, use:

PS1=$'\[\e[7m%\]'"${PS1% }"$'\[\e[0m\] ' 

$'...' is a special way of quoting a string, which will translate \e into <esc>

${VARNAME%SUFFIX} removes outputs VARNAME, but strips off any ending string SUFFIX (in the above cases the final space, since we don't want to invert that in order to see the cursor properly).

Occasionally I find that the above trick is impractical (typically when the need arise to look at some logfile or something on a server which isn't really mine to customize to death), but on those occasions I usually find that all of the above suggested solutions are also too much of an effort, and I just press <enter> for a bit.

Just clear twice! Example:

clear; clear; echo "Hello World" 

In bash I find CTRL+l moves the cursor to the top of the screen, but CTRL+L (i.e. CTRL+SHIFT+l) moves the cursor to the top of the screen, and inserts around a screen of space beforehand. Ideal! Thanks @Anthon.
