Including Hash / in sed command filter
Hello All,

I want to print data in between two lines in a file sample.txt through more or cat command on the screen. For that I am using below sed command to give the BEGIN and END text.

Content of sample.txt

Code:
server01:~ # cat /proc/mdstat

Hello this is a text message 1
Hello this is a text message 2
Hello this is a text message 3
Hello this is a text message 4
Hello this is a text message 5

Code:
server01:~ # df -k

TESTING 1
TESTING 2
TESTING 3
TESTING 4
TESTING 5

Code:
server02:~ # df -k

Command and its output:

Code:
server01:~ # more sample.txt | sed -n -e '/server01:~ # cat/,$p' | sed -e '/server01:~ # df -k/,$d'

Hello this is a text message 1
Hello this is a text message 2
Hello this is a text message 3
Hello this is a text message 4
Hello this is a text message 5

The above method is working fine but since I may have more cat text for server01 in sample.txt so I want to include complete text 'server01:~ # cat /proc/mdstat' in the BEGIN or END in between the sed / / for exact matching. But it gives error when I put like below because the matching string itself contains Hash (/) :

Code:
server01:~ # more sample.txt | sed -n -e '/server01:~ # cat/proc/mdstat/,$p' | sed -e '/server01:~ # df -k/,$d'


Please suggest the way forward

NAME

       irsend - basic LIRC program to send infra-red commands

SYNOPSIS

       irsend [options] DIRECTIVE REMOTE CODE [CODE...]

DESCRIPTION

       Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such
       as TV boxes, HiFi sets, etc.

       DIRECTIVE can be:
	  SEND_ONCE	    - send CODE [CODE ...] once
	  SEND_START	    - start repeating CODE
	  SEND_STOP	    - stop repeating CODE
	  LIST		    - list configured remote items
	  SET_TRANSMITTERS  - set transmitters NUM [NUM ...]
	  SIMULATE	    - simulate IR event

       REMOTE is the name of a remote, as described in the lircd configuration file.

       CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file.

       NUM is the transmitter number of the hardware device.

       For the LIST DIRECTIVE, REMOTE and/or CODE can be empty:

	  LIST	 ""    ""   - list all configured remote names
	  LIST REMOTE  ""   - list all codes of REMOTE
	  LIST REMOTE CODE  - list only CODE of REMOTE

       The SIMULATE command only works if it has been explicitly enabled in lircd.

       -h --help
	      display usage summary

       -v --version
	      display version

       -d --device
	      use given lircd socket [/var/run/lirc/lircd]

       -a --address=host[:port]
	      connect to lircd at this address

       -# --count=n
	      send command n times

EXAMPLES

	  irsend LIST DenonTuner ""
	  irsend SEND_ONCE  DenonTuner PROG-SCAN
	  irsend SEND_ONCE  OnkyoAmpli VOL-UP VOL-UP VOL-UP VOL-UP
	  irsend SEND_START OnkyoAmpli VOL-DOWN ; sleep 3
	  irsend SEND_STOP  OnkyoAmpli VOL-DOWN
	  irsend SET_TRANSMITTERS 1
	  irsend SET_TRANSMITTERS 1 3 4
	  irsend SIMULATE "0000000000000476 00 OK TECHNISAT_ST3004S"

FILES

       /etc/lirc/lircd.conf
	      Default lircd configuration file.  It should contain all the remotes, their infra-red codes and the corresponding timing	and  wave-
	      form details.

DIAGNOSTICS

       If lircd is not running (or /var/run/lirc/lircd lacks write permissions) irsend aborts with the following diagnostics:
       "irsend: could not connect to socket"
       "irsend: Connection refused" (or "Permission denied").

SEE ALSO

       The documentation for lirc is maintained as html pages. They are located under html/ in the documentation directory.
