Thanks to ALL for your reply.
For reply:1 -> I'm getting the output as:
Code:
awk '/^ /' infile
 _1bbb  yes
 c-ccc  yes
 eeeee  yes
 ff  yes

But when I tried something as below, inorder to do conditional manipulation based on the value of $1, I didn't get any output.
Code:
>awk '{ if($1 ~ /^  /) {print $0}}' infile

For reply:2 -> I'm not getting the desired output which I think may be because [:blank:] searches for tab space.

Code:
>awk '/^[[:blank:]]/' infile ---> no output
>awk '!/^[[:blank:]]/' infile
aa  no
 _1bbb  yes
 c-ccc  yes
ddd  no
 eeeee  yes
 ff  yes

FYI, my infile have below contents:
Code:
>cat infile
aa  no
 _1bbb  yes
 c-ccc  yes
ddd  no
 eeeee  yes
 ff  yes

Regards,

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
