===== Searching the Command History =====
==== Incremental searching ====
Incremental means the search begins **before** the searcher has finished typing the string to search for. Bash supports this feature with the //Incremental Backwards Search// (//C-r//), and the //Incremental Forward Search// (//C-s//).
==== Search on ====
Through repeatedly typing //C-r// or //C-s//, older (newer) matching entries are shown and so can be searched through.
==== Finishing the Search ====
There are several posibilities to finish searching:
  * if the found entry matches completely, it can be executed by hitting //Return//
  * if it matches only partially, //C-j// can be pressed to finish the search and allow editing the entry (try this one: //C-j C-x C-e//)
  * if the entry was not found, the search can be aborted using //C-g//. This also restores the original content of the commandline, which may contain parts of the string to search for.
**NB:** the amount of 1337'nes increases from top to bottom!

===== Problems =====
===== ''forward-search-history'' and ''stty'' =====
Normally, //C-s// should activate the Incremental Forward Search. But in nearly every case this leads to a hanging terminal. This comes from [[util:stty|stty]] interpreting //C-s// as stop-signal.

To recover the terminal from this state, a simple //C-q// should suffice.
