Question How to sort lines by strings between ()?
Hello,everyone. I am learning some Info commands.I put all commands and their explanations in a file.

This is a part of it:

Code:
ESC PgUp (scroll-other-window-backward)Scroll the other window backward
ESC Right (forward-word)  Move forward a word
ESC r (move-to-window-line)
ESC TAB (move-to-prev-xref)
ESC Up (prev-line)   Move up to the previous line
ESC v (scroll-backward-page-only)

Now I want to sort these lines by the alphabetical order of the commands' names. The commands' names are between the parentheses and not in the same colomn of lines.

Thanks.

Hi,

What about this?
Code:
$ cat infile
ESC PgUp (scroll-other-window-backward)Scroll the other window backward
ESC Right (forward-word)  Move forward a word
ESC r (move-to-window-line)
ESC TAB (move-to-prev-xref)
ESC Up (prev-line)   Move up to the previous line
ESC v (scroll-backward-page-only)
$ sort -k3,3 infile
ESC Right (forward-word)  Move forward a word
ESC TAB (move-to-prev-xref)
ESC r (move-to-window-line)
ESC Up (prev-line)   Move up to the previous line
ESC v (scroll-backward-page-only)
ESC PgUp (scroll-other-window-backward)Scroll the other window backward
