Bash – How to insert the output of previous command into current command line

bash

$ pidof qqq
12345
$ cd /proc/
           ^ cursor here

And now I want to auto-insert the previous line here. Of course I can manually type 12345 or `pidof qqq`, but how to do it conveniently?

The question is not solely about pidof and /proc, but about any such situation of reusing previous command output.

You can use the following:

cd /proc/$(!!)

Bash – Using text from previous commands’ output

You could use script (use -f to make sure it flushes every time) and you can have all the output in a file.

Use a terminal multiplexer (screen, tmux etc). For instance, for screen http://web.mit.edu/gnu/doc/html/screen_11.html#

Command: copy Enter copy/scrollback mode. This allows you to copy text from the current window and its history into the paste buffer. In this mode a vi-like full screen editor is active, with controls as outlined below.

Other terminal multiplexers surely have more advanced capabilities.

Bash – ignore case but disallow autocomplete if ambiguous

There is a workaround for your problem.

Try:

bind 'set completion-ignore-case on'
bind 'TAB:menu-complete'
bind 'set menu-complete-display-prefix on'
bind 'set show-all-if-ambiguous on'

Type cd h,Tab. Line expands to cd hello.

Then type _, Tab. Line expands to cd Hello_StackOverflow

Press Tab,Tab. Line expands to cd Hello_STACKOVERFLOW/

Explanation:

menu-complete Similar to complete, but replaces the word to be completed with a single match from the list of possible completions. Repeated execution of menu-complete steps through the list of possible completions, inserting each match in turn. At the end of the list of completions, the bell is rung (subject to the setting of bell-style) and the original text is restored. Thiscommand is intended to be bound to TAB, but is unbound by default.

Available since bash-2.02-alpha1

menu-complete-display-prefix If set to On, menu completion displays the common prefix of the list of possible completions (which may be empty) before cycling through the list.

Available since bash-4.2-alpha

show-all-if-ambiguous This alters the default behavior of the completion functions. If set to On, words which have more than one possible completion cause the matches to be listed immediately instead of ringing the bell.

Work together with menu-complete-display-prefix since bash-4.3-alpha
