If you want to copy the output from a command, you can use
pbcopy. To get specific output, use
For example, to copy the entire output of
netstat -an | pbcopy
To only copy the output of open ports (listening):
netstat -an | grep LISTEN | pbcopy
Terminal.app itself does not have a way to use the keyboard to select text, but using a terminal multiplexer like screen or tmux, you can do so in "copy mode". Screen is installed on OS X by default, and tmux can be installed through a third party tool such as Homebrew or Macports. The man page for both programs describes copy mode and how to select text to copy to the clipboard. In the screen man page, more information about navigating copy mode can be found in the
CUSTOMIZATION section under
copy. An excerpt below:
Enter copy/scrollback mode. This allows you to copy text from the cur-
rent window and its history into the paste buffer. In this mode a vi-
like `full screen editor' is active:
h, j, k, l move the cursor line by line or column by column.
0, ^ and $ move to the leftmost column, to the first or last non-
whitespace character on the line.
H, M and L move the cursor to the leftmost column of the top, center
or bottom line of the window.
+ and - positions one line up and down.
G moves to the specified absolute line (default: end of buffer).
| moves to the specified absolute column.
w, b, e move the cursor word by word.
B, E move the cursor WORD by WORD (as in vi).
C-u and C-d scroll the display up/down by the specified amount of
lines while preserving the cursor position. (Default: half screen-
C-b and C-f scroll the display up/down a full screen.
g moves to the beginning of the buffer.
% jumps to the specified percentage of the buffer.
This still doesn't interact with the system's clipboard, so you would have to copy the output in some way, perhaps by echoing the paste buffer contents to pbcopy. Example workflow:
(C-a [ is "hold control press A and then hit [", same for ]. see screen man page.)
- Start screen and do work there.
- Enter copy mode: C-a [
- Navigate using vi keybindings (or set to use emacs bindings per the man page).
- Start text selection with spacebar.
- Hit enter to copy selection to paste buffer. This exits copy mode.
- Paste the buffer with C-a ]
echo 'C-a ]' | pbcopy
(don't literally type C-a ], use the keybinding as described above, use quotes where necessary)
The text you selected should be in the system clipboard and you can paste it into another window. For example the following:
paste [registers [dest_reg]]
Write the (concatenated) contents of the specified registers to the
stdin queue of the current window. The register . is treated as the
paste buffer. If no parameter is given the user is prompted for a sin-
gle register to paste. The paste buffer can be filled with the copy,
history and readbuf commands. Other registers can be filled with the
register, readreg and paste commands. If paste is called with a second
argument, the contents of the specified registers is pasted into the
named destination register rather than the window. If . is used as
the second argument, the displays paste buffer is the destination.
Note, that "paste" uses a wide variety of resources: Whenever a second
argument is specified no current window is needed. When the source
specification only contains registers (not the paste buffer) then there
need not be a current display (terminal attached), as the registers are
a global resource. The paste buffer exists once for every user.
Was from the screen man page from doing the above :).
Now all that said, and you do mention Terminal.app specifically, a new feature of iTerm2 version 0.20.20101102 which is in alpha testing shows:
- Mouseless Selection: Do you often copy-paste text within the same window? Now you can do it without using the mouse. Open the findbar with cmd-f and search for the text you wish to copy. When part of the text is matched, use the tab key to expand the selection to the right by a full word and shift-tab to expand it left to the previous word boundary. It's automatically copied to the clipboard, or you can use opt-Enter to paste the selection immediately.
While is it alpha, I've been using it for all of my Terminal work for about a month and a half and it is quite stable.
