bash,vi,readline – Why ci” (Change Inside Quotes) Doesn’t Work in Bash with Vi Mode Enabled

bashreadlinevi

My favourite way to use bash is with readline's vi mode, enabled with set -o vi. It works perfectly for me, except that ci" does nothing. The change inside X feature does not work.

What can I do to fix this? Why is it not working?

Best Answer

readline's vi-mode is a subset of vi (essentially features that affect a single line, with some allowances for usability). The ci command is not part of vi; it is a vim feature.

Bash – Why Grep Doesn’t Work with Redirection

I get the same behavior that you describe. On Ubuntu 11.10

top | grep "my_program" > top.log

does not produce any output.

I believe the reason for this is that grep is buffering its output. To tell GNU grep to spit out output line-by-line, use the --line-buffered option:

top | grep --line-buffered "my_program" > top.log
