Thanks Yoda i will try to apply this but wat i needed is
i am having a file with | seperated in which i need to search char in 3rd column and replace with null. i need to replace only the coulmn where character occurs in 3rd field
for eg:


Code:
file1.txt
Code:
xx|yy|xx|12

output file:
Code:
xx|yy||12

the above one i achieved with this below code using https://www.unix.com/shell-programmin...#post302841467
Code:
awk 'BEGIN {FS=OFS="|" } $3 ~ /[[:alnum:]]/ { $3="" }1' file

but wat i faced is if there is any column having pipe that should consider as single column
Code:
xx|yy|"xyz|xx"|AAA|12...

not i should achieve my requirement like this
Code:
xx|yy|"xyz|xx"||12

now AAA should replace with null considering as AAA as 4th column if use
Code:
awk 'BEGIN {FS=OFS="|" } $4 ~ /[[:alnum:]]/ { $4="" }1' file

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
