Dear Guru's
I'm using Putty and want to edit a file. I know we generally use vi editor to do it. As I'm not good in using vi editor, I want to convert the vi into something like text pad. Is there any option in Putty to do the same ? Thanks for your response.

rwbytype.d
rwbytype.d(1m) USER COMMANDS rwbytype.d(1m)
NAME
rwbytype.d - read/write bytes by vnode type. Uses DTrace.
SYNOPSIS
rwbytype.d
DESCRIPTION
This program identifies the vnode type of read/write activity - whether that is for regular files, sockets, character special devices, etc.
This is measuring at the application level, so file activity may well be cached by the system.
Since this uses DTrace, only users with root privileges can run this command.
EXAMPLES
This samples until Ctrl-C is hit.
# rwbytype.d
FIELDS
PID process ID
CMD process name
VNODE vnode type (describes I/O type)
DIR direction, Read or Write
BYTES total bytes
DOCUMENTATION
See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
bose descriptions explaining the output.
EXIT
rwbytype.d will sample until Ctrl-C is hit.
