There is a big directory which contains 100k files on the remote server, and I typed command: ls in my putty.
It starts to display a very long file list, and seems never end.
How to stop it, without closing the putty program?
If you are over SSH, you can use escape sequences.
For example to send break, press:
enter, ~ and B
"enter" is of course not typed, just press the enter key (I suppose to "reset" the current command buffer)
Other interesting ones
Terminate time-outing session
enter, ~ and .
Send escape character
enter, ~ and ~
You can list these commands with
enter, ~ and ?
On my system the above prints:
# ~?
Supported escape sequences:
~. - terminate connection (and any multiplexed sessions)
~B - send a BREAK to the remote system
~C - open a command line
~R - Request rekey (SSH protocol 2 only)
~^Z - suspend ssh
~# - list forwarded connections
~& - background ssh (when waiting for connections to terminate)
~? - this message
~~ - send the escape character by typing it twice
(Note that escapes are only recognized immediately after newline.)
