I am trying to write a script but I'm stuck here. See the code please!
aug@august:~/play$ for i in {1..100..4}
> do
> echo "august"
> touch august $i+$2
> mkdir dir
Is there any way to go previous line? I mean there was a mistype, I did in touch august $i+$2. Ipressed ENTER key, so I went for new line. How can I get back to previous line?
bash's command-line editor doesn't support this, either do as anwar suggests or keep everything on one line separated by semicolons or put it into a script file.
On a side note, zsh has features that help with this. The zsh line editor (zle) is a more fully featured editor and supports moving within a multi-line command. When the command becomes too long to handle in zle it has a builtin feature, edit-command-line, which opens up the command-line in your favorite editor. It's usually not bound, try with:
bindkey "^[e" edit-command-line
Alt-e should now activate it, save and quit to go back to the command-line.
